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: Ball Bearing Motors Do Not Require Lubrication.
Routine Cleaning and Lubrication of Flexible Shaft
The shaft should be checked, wiped clean, and relubricated 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 10006) or high quality white lubricating grease.
Exposing the Inner Shaft
1.Remove handpiece
(see page 5).
4.Apply a very light coating of lubrication to shaft starting at the top and working downward to
about one inch from the 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
″ from sheath. Retighten the set
screw in motor connector.
6.Clean exterior of sheath by wiping with a cloth.
7.Hang and run the motor for about 4 to 5 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.
