Shaft and Sheath Adjustment for Handpiece H.20 and H.20D
It is important to check the sheath and shaft tip and properly adjust
them before you attach this handpiece to your Foredom flexible
shaft tool. The tip of the flexible shaft should extend 3/4
″
beyond
the end of the sheath and no more than 7/8
″
or less than 5/8
″
(see above).
On Foredom machines with standard shaft and 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 assembly are fully extended and straight while hanging
or on a flat surface. When the adjustment is correct, tighten the set
screw in the motor connector.
Attaching the Handpiece to the Flexible Shaft
Attach the handpiece by pushing it on the grooved QD (quick
disconnect) fitting on the sheath. Be sure that the keyed tip of the
flexible shaft is properly lined up with the slot in the handpiece
shaft connector by looking into the rear of the handpiece before
pushing it on. If it is not in line, turn the handpiece to the
correct position.
