Exposing the Inner Shaft
1. Remove
handpiece
(see page 5).
2. Loosen set
screw on motor
connector.
3. Slide outer
sheath out of
motor connector
and wipe
shaft clean.
4. Apply a very
light coating of
lubrication to shaft
starting at the top
and working
downward to about three inches from the hand-
piece end. Apply grease with your finger tip or
small brush. Don’t overdo, apply a light film of
grease. Once the machine is running, the shaft
itself will spread the grease. If too much grease is
applied, the excess will work its way into the
handpiece and eventually seep out between the
handpiece and sheath. For this reason, apply a bit
less near the handpiece end of the shaft.
Never operate the motor with the outer
sheath removed from the flexible shaft.
5. Replace and adjust sheath so that shaft key tip
extends 3/4
″
(19mm) from sheath. Retighten the
set screw in motor connector. See page 5, No. 2.
6. Clean outside of sheath by wiping with
a cloth.
7. Hang and run the motor for about 10 minutes
before attaching the handpiece to allow enough
time for the grease to warm up, spread and
drain off. Wipe off any excess grease at tip end
of sheath.
8. Re-attach
handpiece. See
page 5.
IMPORTANT!
Maintenance Procedures
Always make sure your power tool
is unplugged during maintenance
procedures!
It is very important to routinely clean your
Foredom
®
Power Tool and lubricate the shaft
(NOT the motor), especially in areas that
generate a lot of dust.
Dirt and improper lubrication are the most
common causes of poor operation and
excessive wear.
Note: The motor has permanently
lubricated ball bearings and does not
require additional lubrication.
Routine Cleaning of Motors
Foredom motors
need air circulation
through the motor
housing to remove
waste heat and cool
the windings. Inlet
and outlet slots pro-
vide the means for
air flow. However, saw dust and conductive debris
(like metal filings or gold dust) can enter in
through these slots. If not cleaned regularly, dust
can collect, making a bridge between parts, caus-
ing an electrical short.
In high dust environments, Foredom
recommends cleaning the motor every
40 hours of use.
To remove dirt and dust buildup, motor brushes
should be removed, cleaned and replaced, and air
should be blown through the motor.
Routine Cleaning and
Lubrication of Flexible Inner Shaft
The shaft should be checked, wiped clean, and
re-lubricated with grease every 50 hours of use.
With every 200 hours of use, the shaft should be
thoroughly cleaned with solvent and lubricated.
Use Foredom flex shaft grease (p/n MS10006) or
high quality white lubricating grease.
