CHECKOUT PROCEDURES
•
All of the following checkout procedures can be done in any order as long
as they are all accomplished.
Batteries
• Make sure battery clamps are secure, not missing any nuts, corrosion
free and the battery is securely fastened.
• An unsecured battery becomes a 75-pound missile in a vehicle accident.
• Insure the battery terminals are free from any corrosion. If corrosion is
present, clean the terminals with a baking soda and water, to form a
paste. Use a old toothbrush or small scrub-brush, then rinse with water.
• Be careful not to get any of this solution on you or your clothing, it is acid
and will burn you. If there is an excessive amount of corrosion build-up on
the terminals, it needs to be written up and reported to the mechanics.
• This is a primary indicator of voltage regulator malfunction.
Coolant Level
• The P-23 has an open type system. If the truck overheats the excess
overflow will discharge on the ground.
• If you can see coolant in the sight glass then there is no need to remove
the radiator cap.
• If the coolant color in the sight glass has a red or brown tint to it, report it
to maintenance, this means that the rust inhibitors are ineffective.
• If there is no coolant in the sight glass, fill the radiator with the proper
50/50 mixture of coolant/water.
• Only fill it until the sight glass if full, anymore will cause the radiator to
over pressurize.
• There must be a minimum level of 2 inches free space in the top, this is
why the glass is two inches below the opening to allow for normal expansion.
Winterization System
• The winterization system has its own coolant tank.
• The check and the fill is on the top of the truck.
•
To check and fill the tank, remove the lid and check the fluid, if the fluid
is low add the proper 50/50 mixture or water/antifreeze.
Engine Oil Level
• Unscrew the T-handle on the oil dipstick and pull the stick out of the
check tube all the way.
• With a clean towel, wipe off all the oil on the stick.
• Insert the stick completely back into the check tube and remove it all the
way.
• Read the level of the oil on the stick, remembering not to turn the dipstick upside down, keep the stick at least horizontal so you do not get a
false reading.
• Make sure the level is at the full mark, if it is not make sure the engine
has not been run recently.
• If the engine is cool, add more until the level reaches the full mark.
Transmission Oil Check
• The oil check for the transmission is similar to the engine oil check.
• When pulling out the check stick, make sure you keep the end of the
stick pointed down so you do not get a inaccurate reading.
• Contact the mechanics for low levels.
Power Steering Fluid Check
• The oil check for the power steering fluid is like all other stick checks.
• Make sure you keep the stick pointed down so you do not get a false
reading.
• If fluid is needed, fill though the same opening where the check is located.
Water Tank
• Open the lid on the top of the truck and visually check that the tank is
full.
• DO NOT RELY ON THE LIGHTS IN THE CAB!
VEHICLE OPERATIONS
CHECKOUT PROCEDURES
•
•
If the water is not in the top screen you need to fill the tank.
You can fill the tank 2 ways—You can use a hose and take it to the top
and put the nozzle in the tank opening or you can fill the truck from a
hydrant.
Foam Tank
• Make sure the foam tank is full and that the float moves freely up and
down.
• If the P-23 needs foam, fill the tank from the top until you can see it in
the screen.
• If the foam needs to be drained for some reason, the foam drain is located on the left side behind the Foam Transfer Compartment.
Wheel and Lug Nut Check
• Insure that the tires are inflated to the proper pressure.
• Inspect the tires for uneven wear, punctures, or cuts.
• Check that the rims are not bent.
• Check that each lug nut is physically tight.
• Most trucks have a line on the lug nut as well as on the stud, you can
visually check for tightness by checking if the line match up.

CHECKOUT PROCEDURES
•
SPECIFICATIONS
Dry Chemical System
• 500-pound capacity steel storage tank.
• The operating pressure has a range of 220 to 240 PSI
• The relief pressure on the tank is 250 PSI
• The agent used is PKP/Powdered Potassium Bicarbonate.
• The propellant is oil free nitrogen and the capacity of the tank is 300
cubic feet.
• The hand-line is 150’ long has a working pressure of 250 PSI and a
bursting pressure of 800 PSI
• Its nozzle has a conical discharge pattern that can not be changed,
with a discharge rate of 5.5 to 7 pounds of agent a second. So that
means the tank can last anywhere from 70-90 seconds.
All of the following checkout procedures can be done in any order as
long as they are all accomplished.
Batteries
• Make sure battery clamps are secure, not missing any nuts, corrosion
free and the battery is securely fastened.
• An unsecured battery becomes a 75-pound missile in a vehicle accident.
• Insure the battery terminals are free from any corrosion. If corrosion is
present, clean the terminals with baking soda and water, to form a paste.
Use an old toothbrush or small scrub-brush, then rinse with water.
• Be careful not to get any of this solution on you or your clothing, it is acid
and will burn you. If there is an excessive amount of corrosion build-up
on the terminals, it needs to be written up and reported to the mechanics.
• This is a primary indicator of voltage regulator malfunction.
Engine Oil Level
• Unscrew the T-handle on the oil dipstick and pull the stick out of the
check tube all the way.
• With a clean towel, wipe off all the oil on the stick. Insert the stick completely back into the check tube and remove it all the way.
• Read the level of the oil on the stick, remembering not to turn the dipstick upside down, keep the stick at least horizontal so you do not get a
false reading.
• Make sure the level is at the full mark, if it is not make sure the engine
has not been run recently.
• If the engine is cool, add more until the level reaches the full mark.
Coolant Level
• The P-19 has an open type system.
• Coolant is cooled in the radiator by air from the fan and returned to the
engine.
CHECKOUT PROCEDURES
•
The expansion tank on the radiator top section contains a pressure control
and fill cap which prevents loss of coolant.
Fill line connects the expansion tank to the suction side of the engine water
pump. When filling the cooling system, a vent line releases trapped air in the
engine to the expansion tank.
The engine water pump is centrifugal tank, belt driven and mounted on the
front of the engine.
Wheel and Lug Nut Check
• Insure that the tires are inflated to the proper pressure.
• Inspect the tires for uneven wear, punctures, or cuts.
• Check that the rims are not bent.
• Check that each lug nut is physically tight.
• Most trucks have a line on the lug nut as well as on the stud, you can
visually check for tightness by checking if the line match up.
Foam Tank
• The foam tank filler box has knives for draining cans of foam.
• Make sure the foam tank is full. If the truck needs foam, fill the tank from the
top of the tank until you can see it in the screen.
Transmission Oil Check
• The oil check for the transmission is similar to the engine oil check.
• When pulling out the check stick, make sure you keep the end of the
stick pointed down so you do not get a inaccurate reading.
• If the level is low you need to contact the mechanics.
•
•
Winterization System
• The winterization system has its own coolant tank.
• The check and the fill is on the top of the truck.
• To check and fill the tank, remove the lid and check the fluid, if the fluid is
low add the proper 50/50 mixture or water/antifreeze.
• Temperatures below 0º F, re-service with 60/40 ethylene glycol/water.
Water Tank
• Open the lid on the top of the truck and visually check that the tank is full.
• DO NOT RELY ON THE LIGHTS IN THE CAB!
• If the water is not in the top screen you need to fill the tank.
• Make sure you open the lid while filling.
• You can fill the tank 2 ways. You can use a hose and take it to the top and
put the nozzle in the tank opening or you can fill the truck from a hydrant.
Power Steering Fluid Check
• The oil check for the power steering fluid is like all other stick checks.
• Make sure you keep the stick pointed down so you do not get a false reading. If fluid is needed, fill though the same opening where the check is located.
