Repair Service

Factory repairs are done promptly and at reasonable cost.
If you wish, you can send your equipment directly to the
factory marked: “Attention: Service Department”. Include
your street address, daytime phone number and/or email
address, and a brief note describing the problem with the
equipment. Estimates will be made upon request.

Adjust the Shaft and Sheath

Note: This illustration does not apply to slip joint connections.

It is important to check the sheath and shaft tip and properly
adjust them before attaching this handpiece to your Foredom
flexible shaft tool.

The tip of the flexible shaft should extend 3/4
the sheath. This adjustment is made by loosening the set screw
in the motor connector and moving the sheath in or out while the
motor and shaft and sheath are hanging fully extended or laying
on a flat surface. When the shaft is adjusted correctly, tighten the
set screw in the motor connector.

Always make sure your power tool is unplugged
during any maintenance procedure.

speed control and plug into power source.

To Attach Handpiece:

motor is running at about half speed and then
turn it off. While the inner key tip is still rotat­ing, grip the handpiece and push it onto the
sheath tip with one firm motion until it snaps
into place (shown at right). This procedure will
align the key tip into the keyway slot (shown
above). To verify this, insert and tighten an
accessory into collet or chuck, turn on control

Handpiece Locking
Screw on H.25,

The locking screw on the
bottom of your handpiece
prevents unintended release from the shaft and sheath and
keeps the handpiece from rotating on the sheath. Some
users who make frequent handpiece changes, prefer to use
this handpiece with locking screw removed since it is easi­er to switch out handpieces.

maximum speed for the H.35 hand­piece.
The bearings in the H.35 will overheat and may
cause damage if you operate your motor at full
speed (generally

Maintenance and Lubrication

Handpieces: no lubrication is required. Putting oil or grease

into the front or back of these handpieces will damage their
pre-lubricated ball bearings. The collet seat and threads of
the handpiece should be kept free of dirt, chips, dust
or debris.

online maintenance videos at www.foredom.net
