Maintenance Procedures
Always make sure your power
tool is unplugged when conducting
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.
Always disconnect power tool before
cleaning or servicing.
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 provide the
means for air flow. However, saw dust and con-
ductive 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, causing 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
relubricated with grease every 40 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.
Be sure to watch shaft and sheath
maintenance videos on www.foredom.net
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 inner
shaft clean.
4.
Apply a
very
light coating of
lubrication to
shaft starting
at the top and
working down-
ward to about
one inch from
the handpiece
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 motor
over a trash
can and run it
for about 10
minutes before
attaching the
handpiece. This provides 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.
