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
and 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 (hand-
piece end) of
the flexible
shaft (with
handpiece
removed) must extend 3/4
″
(19mm)
beyond the sheath.
Important Note: The shaft and sheath
should be checked and adjusted (if
necessary) even if you received them
assembled and attached to the motor!
To check the shaft and sheath you
must first remove the handpiece which
is easy to do.

Please follow these directions to
assemble and adjust the shaft
and sheath.
To remove:
1. 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 facing upward, turn on the
motor so that it is running at
about half speed and allow
it to slow down. 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. This procedure will align the
key tip into the keyway slot (shown in
drawing at right). 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.
Assembly Instructions
A complete Series SR flexible
shaft power tool
has a motor,
flexible shaft and outer sheath, speed
control (foot or dial) and a hand-
piece. If you purchased a motor and
control, a handpiece is needed to use
the machine. Locate and identify all
components, parts and accessories
you purchased before discarding any
packing list and packing materials
that came with your power tool.

2. With the handpiece removed, place
the entire unit on a flat surface with the
shaft and sheath extended straight as
shown below. Loosen the set screw on
the motor connector. Adjust the exposed
tip (handpiece end) of the flexible shaft
so that it extends 3/4
″
(19mm) beyond
the sheath. This is done by moving the
sheath in or out of the motor connector
(motor end).
3. When the correct adjustment is
made, re-tighten the set screw in the
motor connector and re-attach hand-
piece onto the flexible shaft.
