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.
