Handpiece Lubrication
(See page 8 for handpiece photos.)
8, 18, 20, 25, (25H), 28, (28H),
30
®
, (30H), 35, 43T, 44T, (44HT) and 52:
These handpieces have been permanently lubri-
cated. Their greased-shielded ball bearings should
absolutely not be lubricated. (Handpieces listed
in brackets are for use with Series TXH and LXH
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, lubrica-
tion of the front and back ends of the handpiece
is required. Follow the detailed instructions that
come with your handpiece.
8D, 10D, 15D, 18D and 20D Handpieces with
Duplex Spring Connections: Approximately every
20 hours of operation apply 1 or 2 drops of Fore-
dom oil (Part No. 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 and 15D: 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 distrib-
ute the oil. Lubricate every 100 hours of use.
50 and 50C: 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 (Part
No. MS10008). Follow the detailed instructions
that come with your chisel handpiece.
