Assembly Instructions

Always make sure your power tool is
unplugged during assembly!

After identifying all the components of your

power tool, assemble it in the following manner:

Assembly and Adjustment of Flexible
Inner Shaft, Outer Sheath, & Handpiece

Proper assembly and adjustment of the

flexible shaft and sheath are critical for the

correct operation of your Foredom power tool.

The exposed tip

(handpiece end)

of the flexible

shaft (with hand-

piece removed)

must extend 3/4

″

(19mm) beyond the sheath.

Important Note: The shaft and sheath

should be checked and adjusted (if neces-

sary) even if you received them assembled

and attached to the motor!

IMPORTANT!

Please follow these directions to assemble
and adjust the shaft and sheath.

To check the shaft and sheath you must first

remove the handpiece.

The handpiece is easy to remove

from the flexible shaft.

To remove:

First make sure your power tool

is unplugged. Simply pull the

handpiece off the shaft and sheath

with a firm grip. To Re-attach Handpiece: while

holding the black colored metal outer sheath tip fac-

ing upward, turn on the motor so that it 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 below). This

procedure will align the key tip into the keyway slot

(as shown below at left). To verify

this, insert and tighten an accessory

into collet or chuck, turn on control

to low speed and observe that the

accessory rotates smoothly.

With the handpiece removed, place the entire

unit on a flat surface with the shaft and sheath

extended straight. Loosen the set screw on the

motor connector. Adjust the exposed tip (hand-

piece end) of the flexible shaft so that it extends

3/4

″ (19mm) beyond the sheath, as shown at

left. This is done by moving the sheath in or out

of the motor connector (motor end) as shown

at left.

3. When the correct adjustment is made,

re-tighten the set screw in the motor connector

and re-attach handpiece onto the flexible shaft.
