Adjust Shaft & Sheath

It is important to check the sheath and shaft
tip and properly adjust them before attaching
this handpiece to your Foredom flex shaft
tool. The tip of the flexible shaft should
extend 3/4

″ beyond the end of 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/
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.

Attach Handpiece to Flexible Shaft

Before attaching the handpiece, connect
the motor to the speed control and plug
into power source.

To Attach Handpiece: while holding the black

colored metal outer sheath tip facing upward,
turn on the control so that the 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 to a low
speed and observe that the accessory
rotates smoothly.

To Remove Handpiece from
Flexible Shaft:
