Maintenance and Lubrication
Handpieces H.18 and H.18SJ never need
lubrication. Putting oil or grease into the
front or back of these handpieces will
damage their pre-lubricated ball bearings.
Flex Shafts:
Cleaning and lubrication
should be performed every 50 hours of use:
First be sure to unplug your power tool.
Remove handpiece and then loosen set
screw in motor connector (see previous
page) and remove sheath. The exposed
shaft should be wiped clean with a cloth
and solvent. Apply a
light film
of Foredom
grease (part no. MS10006) to entire length
of inner shaft. Reconnect shaft and sheath,
following adjustment procedure on previous
page and run motor for ten minutes before
reconnecting handpiece. Turn off motor,
wipe off excess grease from tip of drive
shaft and reconnect to the handpiece.
