COMBINE FUNCTION
The threshing operation is accomplished by a hydraulically driven, 15-1/4” diameter, variable speed
raspbar cylinder and one adjustable, under-slung, grated style concave (optional spike-tooth
threshing cylinder and matching concave are available for rice and related crops). A strawpuller
positioned directly behind the threshing cylinder prevents cylinder wrapping and assists the
movement of plant material through the machine. Adjustable / removable curtains are also utilized
to prevent seed rebounding and to control threshed material flow.
FIGURE C-1 Threshing Function Diagram
Cleaning is achieved in two stages:
1. Threshed material falls upon the first mechanically driven sieve where seed and smaller material
fall through the sieve on to an upper internal conveyor. The conveyor carries separated material on
to a finer mesh lower sieve. The second sieve removes smaller material and allows the seed to fall
through onto a lower internal conveyor. This conveyor drops the seed into the winnowing blower air
stream.

2. The large winnowing blower, located at the lower portion of the machine, directs an adjustable air
stream across the discharge area of the lower sieve and conveyor. In this secondary cleaning
stage, the remaining debris in the seed sample is discharged out the rear of the machine.
Seed falls through the winnowing blower air stream and into the venturi tube (or optional air lock)
and cyclone blower air stream. The cyclone blower air stream lifts seed through the venturi tube to
the cyclone seed hopper. Several different options direct the seed to a number of different locations.
To harvest weight and moisture test samples, the cyclone seed hopper dumps the sample into the
weigh hopper. Automatic weight and moisture tests are preformed in the weigh hopper, while the
next plot is being harvested. Tests are completed in the weigh hopper as the next plot is delivered
into the cyclone seed hopper. This two-stage sample data gathering technology allows harvesting
plots at a high rate of speed, and still allows automatic weight, moisture and data storage equipment
to function within its recommended time requirements.

OPERATION
SPC 40
OPERATOR’S MANUAL
HEADER FUNCTION
(See Diagrams in the Parts Manual)
CORN HEAD:
A corn head functions by a pair of tapered snapping rollers which pinch the stalk and pull it down
and through the head past an adjustable stripper plate, this plate strips the ears from the stalk. The
ears are carried up the head by a set of steel flight gathering chains to the throat. In the throat the
ears are augered to the center of the throat where they are picked up by a second set of drag
chains which deliver the ears to the threshing chamber.
It is important to note that the drag chains should match the ground speed. This means the
gathering chains in the head should run slightly faster than the stalks entering the head. If the
chains run too slowly the stalks can be pushed forward, increasing the chances of plugging. If the
chains run too fast, stalks are jerked into the snapping rolls, possibly knocking off ears or shearing
off stalks. See Corn Head manual for detailed operation information.
STANDARD PLATFORM HEAD:
A Standard Platform Head functions by cutting the material off with a horizontal moving sickle. A
reel then pushes the plant up onto a chevron style conveyor. This conveyor carries the material up
the head where the plant material is fed into the threshing chamber with the use of an upper pinch
belt. Adjust the reel speed so that bars of the reel match or are slightly faster than the ground
speed so that the plants are gently placed on to the conveyor. If the reel is set too fast seed is
knocked off the plant and lost. If the reel is set too slow the plant is pushed forward increasing the
chances of plugging and sample loss.
ROW CROP HEAD:
A Row Crop Head functions by first, grasping the plant between two opposing convoluted gathering
belts, while the plant is cut off by a rotating knife. The gathering belts transfer plant material onto a
chevron style belt in the throat. This belt carries the material up the throat to an upper pinch belt.
The upper pinch belt helps feed the material into the threshing chamber. It is important to note that
the speed of the gathering belts should match or just exceed the ground speed. If the belts run too
slowly the plant can be pushed over forward increasing the chances of feeding problems. If the belt
runs too fast the plant is pulled out of the ground, possibly knocking off seed and drag dirt debris
into the head.

OPERATION
SPC 40
OPERATOR’S MANUAL
OPERATOR CONTROL FUNCTIONS
A combine has four distinct operations: feeding, threshing, separating, and cleaning. These
operations are interrelated to produce a good overall harvesting result. Because of these
relationships, the proper adjustment to fix a problem may not be obvious. What appears to be a
cleaning problem could actually be caused by feeding the machine too fast (a feeding problem).
Making adjustments quickly and correctly will allow efficient harvesting. Use this section to become
familiar with the controls and the effects it will have on the machine. Use SECTION D
TROUBLESHOOTING to determine possible causes for harvesting difficulties and probable
solutions. All intended operators must be familiar with the functions of the machine for operator
safety and proper harvesting results.

ROLLER MILL (GRINDER) FUNCTION
The roller mill devitalizer (or grinder) functions by forcing harvested seed between two fast moving
drums with hardened teeth on their surfaces (see FIGURE C-8). Due to the high speed and rough
surfaces of the roller drums the individual seeds are crushed and separated into many small pieces,
thus devitalizing the seed.
The grinder is automatically fed material from the grain tank that collects harvested seed from either
the weigh system or the bulk harvesting cyclone. The grain tank contains a six inch auger that is
removable from the left side of the machine (SEE MACHINE CLEANOUT SECTION) for
instructions.
WARNING: ALL grinder guards must be in place for grinder to operate properly.
Failure to install ALL guards may result in personal injury and/or machine damage.

AIR COMPRESSOR FUNCTION (OPTIONAL)
This machine is equipped with a hydraulically driven air compressor. Use of compressed air is
recommended to clean out the internals of the machine. The compressor is equipped with a
blowgun and recoiling air hose for ease of use and mobility. A thirty gallon air tank allows for even
flow and extended cleaning time.
CAUTION: Do not point air wand at anyone. Blown objects and/or
pressurized air can cause serious injury.
WARNING: Turn off machine and remove key before servicing
equipment. Never operate with out belt guard. Rotating parts can
cause serious injury or death.
CAUTION: Compressor parts may be hot even if stopped, hot parts can cause
burns
OPERATION
With the combine running, turn the air compressor switch to on, the compressor will build pressure
in the storage tank to 90 psi before a pressure switch automatically stops the hydraulic motor. As
the blowgun is used the compressor will restart to maintain 90 psi. A backup unload valve on the
tank is set to relieve pressure at 100 psi (if the pressure switch fails) to keep from damaging the
compressor. Move the air compressor switch to off when not in use.

MACHINE SETTINGS AND ADJUSTMENTS
Before making any adjustment:
1. Identify the problem.
2. Find the possible causes in SECTION D TROUBLE SHOOTING.
3. Understand the possible causes and associated adjustments that can be made.
4. Choose an adjustment and follow the adjustment procedure.
WARNING: Adjusting machine while moving parts are engaged, can cause
serious injury to operator and/or damage to the machine. Stop machine,
disengage clutch, head and threshing cylinder, then shut off engine before
making any adjustments.
Ground Speed
Ground speed is a critical aspect for proper harvesting. Ground speed determines how fast the
crop is harvested and delivered to the threshing chamber. If ground speed is too high the
threshing chamber will do a poor job of threshing too much material. It can cause the threshing
cylinder to become slugged or plug up the sieves. Use the ground speed control lever and/or foot
control (optional) to adjust ground speed. Speed adjustments are required as field conditions
change, from field to field, or from one section of the field to another. In wet conditions reduce
ground speed and reduce header speed accordingly.
Winnowing Blower
The Winnowing Blower creates air flow for the cleaning system. Both the speed and volume of air
are adjustable. Air speed is adjustable by a variable pitch sheave located on the blower shaft. To
adjust sheave:
1. Loosen set screw holding key between hub and sheave half. Do not loosen set screw holding
key between hub and shaft.
2. Remove key
3. Rotate sheave clockwise (decrease distance between sheave halves) to decrease speed,
counter-clockwise (increase distance between halves) to increase speed.
4. Rotate sheave in half rotation increments, replace key, and tighten set screw.
Adjust air volume with shutter located just behind winnowing blower on left side of the machine. If
seed is being blown out the rear of the machine close the shutter until only seed falls through air
stream, but trash is blown out the rear of the machine. If the sample is ‘dirty’ the shutter should be
opened. If the shutter is opened completely it may be necessary to increase the speed of the blower
shaft. In this case the problem is not normally due to the winnowing blower, but a problem with the
threshing cylinder and concave clearance. Try decreasing threshing cylinder speed, or increasing
concave/cylinder clearance before adjusting sheave.
Threshing Cylinder Speed
This setting is possibly the most important adjustment to produce a clean sample, because of its
ease of adjustment. Use the TABLE C-1 Initial Cylinder / Concave Settings Chart below to
determine initial settings. When the crop is wet speed up the threshing cylinder and increase the
clearance. In dry conditions it is possible to slow down and reduce the cylinder / concave clearance.
Notice the speed of the threshing cylinder as the crop enters the threshing cylinder. If the speed
slows significantly it is necessary to reduce the ground speed and header speed accordingly and/or
C-20
OPERATION
SPC 40
OPERATOR’S MANUAL
increase the cylinder / concave clearance. Examine the cleanliness of the sample. When the
threshing cylinder is set too fast plant material can make its way into the sample, too slow and
material may be lost out the rear of the machine.
Cyclone Blower
The cyclone blower creates air flow for the pneumatic seed delivery. The cyclone blower speed
should be fast enough to blow seed into the cyclone without plugging, but not fast enough to blow
seed out the top of the cyclone. Adjust speed using adjustable pitch sheave. NOTE: This machine
may be equipped with an optional 6" air delivery system with a hydraulically driven blower. If
equipped with this option the cyclone blower speed is not user adjustable, please contact ALMACO
with questions.
Threshing Cylinder / Concave Clearance
Cylinder / Concave clearance is another critical aspect to produce proper threshing action without
suffering seed damage. Examine the discharge at the rear of the machine. Reduce clearance if
there is still seed on the plant, which may require the ground speed and header speed to be
reduced. Increase clearance and/or slow the threshing cylinder if the discharge or samples are
severely damaged. This machine is equipped with an electric concave clearance adjustment
system. NOTE: The electric motor that drives the concave adjuster is protected by a six amp
automatic reset circuit breaker.
To adjust concave setting, proceed as follows:
1. Locate desired crop or similar crop on TABLE C-1 Initial Cylinder / Concave Setting Chart below.
This chart contains the recommended starting speeds and clearances. This setting may need to
go up or down depending on crop and field conditions. When checking concave clearance
measure clearance between second concave bar and cylinder raspbar. NOTE: Cab indicator
readings are approximate, measure concave clearance to verify setting.

2. Ground speed
3. Header height
4. Threshing cylinder speed
5. Cylinder / concave clearance
6. Discharge at rear of machine

CORN HEAD
(Review John Deere Corn Head Operator’s Manual sections: 05, 25, 30, 35 and 40 for additional
information.)
Stripper Plate Adjustment
ALMACO corn heads are equipped with an adjustable stripper plate. Standard setting of stripper
plates is 1-1/2’” apart at the front and 1-3/8” apart at the rear. The size of the ears, stalks, and
amount of trash taken in will determine spacing. Set taper by moving adjustable plate until the
clearance between two plates is 1-7/16” at the middle of the plate.
1. Loosen jam nut on left side of head.
2. Turn nut clockwise to tighten clearance; counter-clockwise to open spacing.
3. Tighten jam nut down.
4. Loosen 2 bolts on top of chain wear plate (fixed plate side).
5. Adjust fixed plate until 1/8” taper is achieved.
6. Be sure wear plate is just touching gathering chains.
7. Tighten bolts.
Optional Stripper Plate Adjustment (from cab)
Optional electric/hydraulic stripper plate adjustment from the cab is available. If equipped, the
stripper plates can be adjusted via a switch on the main dash panel (located in switch bank "C").
Press the switch to increase or decrease stripper plate clearance. NOTE: Although the adjustable
plate can be moved from the cab, initial taper of the stripper plates must be manually set (see basic
stripper plate adjustment above).
Header Height
There are no gauge wheels on a corn head. Header height is a matter of preference and is
dependent on the condition of the crop. In standing corn the header only needs to be run slightly
below the ears. When harvesting fallen stalks lower the head so that the snout lifts the stalks before
they enter the rollers. When header is too low rocks can be picked up in the head, causing serious
damage to the machine. Use header lift switch located on the FWD/REV lever to make height
adjustments.
OPERATION
C-23
SPC 40
OPERATOR’S MANUAL
Snout Adjustment
Snout should be set so that it gently lifts fallen crop, but does not ride on the ground and push dirt
into the snapping rolls. In standing crops, adjust the height of the snout points several inches above
the ground. In down crop conditions, adjust points to lift the stalks before they enter gathering belts.
Adjustment is most easily done when head is raised.
WARNING: Crushing hazard. To prevent injury or death put safety stops in header lift
hydraulic cylinders.
1. Remove access panels on outside tin.
2. Pull chain through slot and remove hairpin.
3. Replace hairpin through chain with snout in desired position.
4. Replace side panels.
5. Unlock Cam-Loc at the top of the center snout and pivot snout up.
6. Pull chain through slot and remove hairpin.
7. Replace hairpin through chain when snout is in desired position.
8. Lock snout back down with Cam-Loc.
9. For fine adjustment: Loosen jam nut on under side of snout. Turn eye bolt to desired position.
Tighten jam nut.
Header Speed Adjustment
Header speed is very critical to reduce plants from hanging up in the head, as well as promoting
good feeding into the threshing cylinder. Header should be set equal or slightly faster than the
ground speed. When the header speed is properly set, plants will stand straight up in the gathering
belts. Adjustment to the header speed will modify threshing cylinder speed. Use border rows to
practice and set initial speed.
1. Determine ground speed, slower in wet conditions; faster in dry conditions.
2. Engage clutch.
3. Be sure hydraulic system is warm and running smoothly. Allow hydraulics to warm up on cold
days.
4. Adjust threshing cylinder speed using knob in cab. (See Table C-1 Initial Cylinder / Concave
Settings Chart).
5. Set header speed to a mid-range speed, using dial in cab.
6. Begin harvesting. Adjust the header speed and/or ground speed so that they are equal. If
header speed is too slow, the plants will be pushed forward before they are cut and will bunch up
in the head causing feeding problems. If header speed is too fast, plants will be jerked into the
belts possibly knocking off seed and drawing dirt and debris into the head.
7. Continue to adjust threshing cylinder speed to compensate for header speed adjustment.

ROLLER MILL SETTINGS AND ADJUSTMENTS
Roller Spacing Adjustment
The spacing or “gap” between the grinder drums is critical to achieve proper devitalization of the
harvested seed. The drums must be adjusted close enough to completely crush the seed, but not so
close that interference between the drums occurs or excess work is performed.
WARNING: DO NOT make any adjustments or perform any maintenance to the roller
mill until the machine is shut down and properly locked-out. Serious injury or death can
occur unless proper procedures are followed.
Roller drum spacing adjustment is accomplished by changing the location of the spring loaded
drum.
1. Loosen the eight roller gap adjusting nuts (see Item 1 in FIGURE C-10). Turn adjusting nuts
clockwise to increase drum spacing and counter-clockwise to decrease spacing.
2. Be sure to adjust all four adjusting studs equally to maintain proper alignment of drums.
CAUTION: Alignment between the roller drums is critical. Improper alignment may
cause serious machine damage.
3. Remove the drum guard panel and magnet mounting plate (located under drum guard panel)
to aid in checking drum alignment. Using a long feeler gauge, check alignment between
drums all along their length.
4. After drums are properly adjusted and aligned make sure all adjusting nuts are firmly
tightened and all guards are in place (SEE TABLE C-2 for gap settings).
5. Start the machine, turn PTO switch "ON" and listen for excess noise from grinder. Increase
engine speed and continue to monitor the grinder. Once the grinder function is verified
resume harvesting.

the drum when material is fed into the grinder inlet.
Adjusting nut
Jam nut
Drum tension
springs
(2 per side)
FIGURE C-11 Roller Mill Front View
Adjustment of the tension springs will cause more or less pressure to be maintained against the
adjustable roller drum. As material flow is increased (by increasing the grain tank auger speed) to
the grinder more pressure will be required against the roller drum to maintain proper seed
devitalization results. If a more uniform grinding sample is desired the roller drum pressure may
need to be increased or the flow of material to the grinder may need decreased.
CAUTION: Increasing the roller tension springs beyond recommended levels may
cause excessive wear on grinder components. DO NOT fully compress springs for
any reason, this will result in grinder and/or drive component damage.
Adjustment procedure:
1. Loosen jam nut above springs (SEE FIGURE C-11).
2. Tighten adjusting nut toward spring to increase spring pressure, loosen to decrease
spring pressure (SEE FIGURE C-11).
3. After adjustment is achieved, tighten jam nut against adjusting nut. Make sure all springs
are adjusted to the same tension to ensure proper grinder operation. The compressed
spring length should be between 4.625” and 4.375”, DO NOT compress springs
beyond than 4.25”.

CAUTION: Read and follow all safety decals and instructions when cleaning the
machine. Failure to follow safety instructions may result in machine damage
and/or personal injury.
Grain Tank Cleaning
The grain tank is designed to perform two functions: (1) serve as a holding area for harvested grain
and (2) control grain flow to the grinder. The grain tank control material flow to the grinder via the six
inch auger located in the floor of the tank. This auger runs anytime the grinder is engaged and its
speed is controlled by the operator from the cab.
The grain tank auger can be removed without the use of tools by following the procedure outlined
below.
WARNING: The machine must be shutdown and properly locked-out before
removing the auger. Failure to do so may cause serious personal injury.
Grain Tank Auger Removal:
1. Open the grain tank access panel located on the left side of the machine, directly below
the weigh system (see FIGURE C-12).
2. Firmly grasp the end of the exposed auger and pull in line with the auger bed until about
12” of the auger is slid out beyond the grain tank wall. This will disengage the drive shaft
from the auger center tube.
3. Continue sliding the auger out of the grain tank until it is completely removed from the
tank.
NOTE: It may be helpful to have a second operator hold a container below the auger
as it is slid out to catch any excess seed left in the tank.
4. With the auger removed the grain tank can be cleaned of seed and inspected.
Grain Tank Auger Installation:
1. Follow the above instructions in reverse.
2. When the auger end reaches the auger drive shaft some rotation of the auger may be
necessary to properly align the hex shaft to the auger center tube.
3. IMPORTANT: Make sure the auger is fully engaged on the auger drive shaft and none of
the auger is hanging out beyond the grain tank access door.
4. With the auger fully installed close and latch the grain tank access door, check for proper
installation by starting the machine and engaging the PTO, visually check for auger
rotation through the rear cab window.

Overall Machine Cleaning
This machine has been constructed to allow for the easiest possible cleaning and inspection. Most
large components, including the cab, grain tank and engine mounts, have all been attached to the
main chassis with one inch spacers to allow access underneath them. Also most hydraulic hoses
have been bundled and wrapped to ensure no seed becomes trapped between hoses.
After the machine has been completely cleaned excess seed may be gathered into a container for
devitalization using the grinder. The grinder has a manual feeding door located between the grain
tank outlet and grinder inlet (see previous ROLLER MILL FUNCTION section).
Compressed air quick-couplers have been installed all around the machine’s exterior and interior to
aid in cleaning. A flexible hose and wand are also included with the machine to utilize the air
couplers (see AIR COMPRESSOR FUNCTION section).
WARNING: Never use compressed air to clean off clothing or other body parts.
Compressed air can cause serious bodily injury.

ELECTRICAL SYSTEM
WARNING: Shut off the engine and use the battery disconnect switch
to Lockout / Tagout the machine before servicing electrical system
(See FIGURE B-1). Electric shock will cause serious injury or death.
FUSES:
There is one 15 Amp in-line fuse between the ignition switch and the lights switch. Additional fuses
may be installed with individual options. If required to change fuse replace with fuse of same
amperage and of the same style.
CIRCUIT BREAKERS AND HEAVY DUTY RELAYS:
There are a number of circuit breakers on the standard combine. A 20 Amp breaker (#18650), (2)
30 Amp breakers (#18517), and a 40 Amp breaker (#18986) are located under the gage panel. The
20 Amp breaker supplies power to hazard lights. A 30 Amp breaker supplies power to oil cooler fan,
the other powers the ignition switch. The 40 Amp breaker powers the starter relay, and optional
glow plugs.
P&B (CUBE) RELAYS:
The relays used for combine functions are located under the gage panel on the right side of the
driver. To replace a P&B relay (#18916), pull the relay cube straight up to remove. Do not remove
the white plastic retainer from the front of the socket (#18915).
LIGHT SERVICE:
If several lights go out at once, check the appropriate fuse(s). If only one light is out, it may be the
bulb or a loose connection. The lights, bulbs, and part numbers used on the combine are in the
following list:
1. Running Lights
The headlights, rear lights, grain tank lights, etc. are a sealed beam off-road light. They draw 2.5
amps and can only be replaced as an assembly (# 18041). Optional halogen lights (#18570)
draw 4 amps.
2. Interior / Auxiliary Lights
These 2 bulb accessory lights are used in many locations on the combine. These lights draw
approximately 0.6 amps and are purchased as replacement bulbs (ANSI 1895 or # 18283), amber
and clear lenses (#18056,18060), or entire assemblies (# 18061).
3. Switch / Gage Lights
The lights used in the switches and gages are unique to the manufacturer and replacements may
be hard to find. The light for the SWF rocker switches can be purchased as an assembly
(#18874) or replacement bulb (#18888). The replacement bulb for the Datcon gauge lights is part
number (#16049).
For questions concerning a specific component or for assistance on servicing your
equipment call ALMACO for assistance.

SPC 40
OPERATOR’S MANUAL
HYDRAULIC SYSTEM
The ALMACO SPC-40 Combine utilizes hydraulic systems to provide power to the components
used for threshing, ground drive, steering, header lift, and various functions.
Power is supplied directly by a 138 hp water-cooled diesel engine, which drives two variable
displacement pumps and two fixed displacement auxiliary gear pumps. The first (closest to the
engine) pump supplies hydraulic fluid, through an adjustable valve, to the threshing cylinder motor,
and head motor. The second (middle) pump supplies power to the ground drive and is controlled by
the forward reverse control lever. The third pump contains two fixed displacement sections. The
front section (closer to the engine) supplies oil to the roller mill drive motor and hydraulic cyclone
blower (if equipped), the second section supplies oil for: hydraulic power steering, header lift
cylinders, grain tank auger motor and air lock drive motor (if equipped).
HYDRAULIC RELIEF VALVES
NOTE: All hydraulic relief valves are pre-set at the factory. Contact ALMACO before
making any adjustments.
RECOMMENDED HYDRAULIC RELIEF OIL PRESSURE SETTINGS:
a. Threshing cylinder: 4500 psi port GA - 4500 psi port GB
b. Ground drive: 5000 psi
c. Auxiliary pump (front section): 3000 psi – Operates grinder
d. Auxiliary pump (rear section): 2000 psi – Operates auxiliary functions
e. Header: 4500 psi

Ensure the battery disconnect switch is “ON”.
Set the engine speed control level (throttle) to idle position.
Put threshing cylinder lever to neutral.
Make sure the ground drive control is in neutral.
Make sure the clutch switch is in the off position.
Turn off all accessory augers.
Insert key, rotate key clockwise to the start position and hold, until engine starts.
When the engine starts, release the key and adjust engine speed for warm up (see engine
manual).
CONVEYOR AND ROLLER ADJUSTMENT
When installing replacement belts position the V-guide on the inside of the belt so that it rides in the
center of the V-groove in the roller. All conveyors should run straight and evenly across roller
surfaces without binding or scuffing the side frame. Procedure for proper adjustment is listed below:
1. Determine the cause of malfunction.
NOTE: Belts may stretch somewhat during the break-in period and may require tension
adjustment.
2. Locate the adjustment assembly on either side of roller.
3. Loosen the stop nuts along the threaded rod and draw or extend the rod to obtain the desired
adjustment.
4. Should the conveyor run to one side, extend the threaded rod on that side to correct.
5. Proper Tension - Adjust tension so that all slack is removed and the belt runs evenly. Avoid
over-tightening.
6. Retighten all jam nuts securely.
NOTE: Over tightening the belt can cause laces to pull apart or break rollers.
MAINTENANCE
E-9
SPC 40
OPERATOR’S MANUAL
HIGH PRESSURE WASHING
(Water and Mild Solvent)
High pressure cleaning with water and mild solvent is advisable provided the following points are
observed.
1. Lightly wash entire machine with solution to float abrasive particles off the machine, which might
otherwise be blown into bearings and other critical surfaces as the cleaning procedure continues. A
recommended safe distance is at least 2 to 3 feet between nozzle and machine.
2. Avoid close contact of nozzle to machine (less than 12" to 15"), as high pressure jet stream at
this distance imparts a cutting action which will lift and remove paint. In addition, close nozzle
contact may also blow grease from bearings and other lubricated surfaces, leaving exposed parts
susceptible to rust and wear.
NOTE: Lubricate all bearings and other lubricated surfaces, after washing and run
machine for a short period to aid in moisture removal.
3. Engine may be washed totally, but avoid trapping moisture in electrical components, and do not
wash a "hot" engine with cold water, as the differential in temperature could cause cracking of
exhaust manifold and other cast components.
4. Mild solvents of a non-flammable nature may be suitable for cleaning, provided manufacturer's
specs are compatible with alkyd enamels, rubber and plastics as used on the self-propelled
combine units.
5. Using steam as a cleaning agent is not recommended by ALMACO, as steam is viewed as a
potentially destructive agent to plastics, paint and rubber and promotes rust and corrosion of
components, which are not immediately protected after cleaning.
