Head Maintenance
• Only use the contra angle head provided with the cordless handpiece or one that is
sold by LightSpeed Technology Inc. specifically for the LightSpeed EndoPAL
handpiece. Failure to do so will void the warranty.
• Please follow the contra angle maintenance and sterilization instructions between
each patient use.
• Steam autoclaving is the only acceptable sterilizing method. Remove from
handpiece and autoclave between patient uses. Sterilize between 121°C and
132°C for 15 to 20 minutes at 15-PSI minimum pressure. Follow manufactures
directions of the unit you are using for autoclaving. Never autoclave with an
instrument in head. Allow head to cool to room temperature before use.
• You may use rubbing alcohol to wipe off the head but this is not a sufficient
sterilization process.
• Lubricate the head with handpiece oil between each use and prior to autoclaving.
Clean off any excess oil that could seep into handpiece body, damage its
components or get into the patient’s mouth.
Attaching and Removing Heads
• Turn collar portion only: clockwise to tighten, counterclockwise to loosen. Use
caution not to strip threads or attempt to turn any portion of the head other than the
contra angle collar.
• Open the latch before removing or attaching the head as the latch gets in the way
of turning the collar.
• Ensure head is properly connected before attempting to use handpiece.
Charging and Batteries

Figure 4. Charging Position
• Place handpiece in cradle on its side as shown in Figure 4
then insert charger plug into back of handpiece body. Plug
charging unit into AC outlet according to Fig 6a or 6b. Normal
charging cycle is 60 - 120 minutes (1 - 2 hours). The charger
may take slightly longer to charge the handpiece due to the
actual room temperature and other charging variables. You may
leave the handpiece connected to the charger for longer than the
specified time, such as leaving it charging over the weekend.
