MAINTENANCE
HANDPIECE
Keep the handpiece clean for proper operation.
Cleaning is necessary if operation becomes sluggish,
erratic, or fails. Refer to FIG. 10 and the instructions
below for the proper way to clean a handpiece.
• Remove the piston and spring from the
handpiece.
• Wrap each separately in a sheet of writing or
printing paper.
DO NOT USE paper towel, tissue, or newsprint.
• Hold the wrapped piece. Buff and polish each
piece with the paper to remove any dirt or
residue.
• Remove piece from paper. For grooved pistons,
fold paper to create a thick edge. Insert the paper
edge in each piston groove. Use the same folded
paper to clean open space in spring.
• Twist the paper to a point that will fi t into the
handpiece barrel. Insert and rotate the paper to
buff and polish the inside until clean.
• Reassemble handpiece.
IMPORTANT NOTE: DO NOT LUBRICATE
PISTON, SPRING, OR BORE.
FOOT THROTTLE
The throttle requires little maintenance with proper use.
Remove any dust, debris, and metal chips from foot
throttle to clean periodically. Place a drop of oil on the
throttle hinges to prolong spring life and prevent rust.
When sweeping or vacuuming, place foot throttle on
bench or chair.
