Attaching Accessories to Handpieces
Quick Change Type
— continued
20, 20D, 20SJ Handpiece:
This handpiece has a lever
action collet release mech-
anism. Wait for the motor,
flexible shaft, and accesso-
ry to come to a complete
stop before turning the lever to open the collet
and remove or insert accessory (2.35mm or
3/32 ″ only). Turn lever 90˚ to left or right to open
collet and change an accessory. To close the col-
let turn the lever back to the position parallel to
the handpiece.
52, 52D, and 52SJ
Handpieces:
These quick change hand-
pieces have a unique
push/pull collet release
mechanism for rapid
accessory changing
(2.35mm or 3/32 ″ only).
Wait for the motor, flexible shaft, and accessory
to come to a full stop before opening the collet.
After accessory has stopped rotating, pull the
top grip forward with one hand while holding the
bottom of the handpiece with the other. Remove
the accessory and insert the shank of the new
one fully into the collet. Push the top and bottom
portions together.
Chisel Type —
50 and 50C Handpieces
(50C includes set of
six chisels):
Inserting a chisel into this reciprocating handpiece
should be done while the motor is in the “off”
position, or with the handpiece disconnected.
Loosen the locking nut with the 12mm spanner
wrench provided by unscrewing it counterclock-
wise. Insert the tang fully into the plunger shaft.
Tighten the locking nut clockwise until tool is
held securely. Do not over tighten.
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
lubricated. 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, 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, and 52D
Handpieces with Duplex Spring Connections:
Approximately every 20 hours of operation
apply 1 or 2 drops of Foredom 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 for-
eign 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.
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.
