, (30H) 35, 43T,
44T, (44HT) and 52
: These handpieces have been
permanently lubricated. Their greased-shielded
ball bearings
should absolutely not be lubricated.
(Handpieces listed in brackets are for use
with Series SRH models only.)
10 and 10D: Lubrication should not be required
for the first 2–3 months of continuous use.
Then, approximately every two weeks of use,
lubrication of the front and back ends of the
handpiece is required. Follow the detailed
instructions that come with your handpiece.
8D, 10D, 15D, 18D, 20D, 52D, 55D
and 56D Handpieces with Duplex Spring
Connections:
Approximately every 20 hours of
operation apply 1 or 2 drops of Foredom oil
(MS10005) into the hole in the duplex spring
collar next to the sheath connector. This will
provide sufficient lubrication for both the duplex
spring connection and the handpiece spindle.
15: Clean off any dirt to prevent foreign
matter from falling inside the handpiece. Put
two drops of Foredom oil into the oil hole in the
side of the housing. Run the handpiece slowly
to distribute the oil. Lubricate every 100 hours
of use.
55A, 55D, 56A, and 56D: It is important to
regularly lubricate the gears and spindle of these
handpieces. Apply one drop of Foredom handpiece
oil in oil holes every hour of continuous use.
Follow the instructions above for duplex spring
lubrication.
50: After every 200 hours of use you should
clean and lubricate this handpiece. The old
grease must be cleaned off of the interior cam
chamber and replaced with new lubricant.
Follow the detailed instructions that come with
your chisel handpiece.
