Maintenance
The MH-145A has permanently lubricated ball bearings that do not
require lubrication. Putting even a small amount of oil into the
handpiece can damage it.
Cleaning Handpiece:
Use the Handpiece in as clean and dust free an environment as possible.
If the Micro Motor Handpiece is used for woodcarving, it should be
cleaned after every use. Open handpiece and wipe dirt, chips or dust out
with a clean cloth. A cloth with a small amount of alcohol solution can be
used to clean outside of handpiece if necessary. Do not use any other
cleaning fluids or immerse handpiece in any liquid. The MH-145A
Handpiece is not autoclaveable.
Checking/Changing Carbon Brushes:
A spare set of carbon brushes is supplied with each handpiece. Depending
on how long the handpiece is used each day, the brushes should be
checked for wear periodically (about every 200 hours of use) and replaced
when the brush is less the 2mm (5/64") long.
To Check/Replace Motor Brushes:
1. Unscrew protective cap from rear of motor (see Figure 5) by turning in
counterclockwise direction while griping handpiece body. (It has a
standard right hand thread.)
2. With small crosspoint screwdriver remove screws and brush assemblies
one at a time. Check length of carbon brush from spring to curved side of
brush. Brushes should be removed, examined, and replaced (if
necessary) one at a time. Pay careful attention to the orientation of
the brush curve in relation to the curve of the motor armature.
This same orientation must be maintained when replacing brushes.
3. Re-insert brush assembly or new brush assembly into brush tube.
Replace and tighten screws.
4. Screw protective cap back onto rear of motor housing so that top of
brush assembly is completely covered.
