Maintenance
The MH-011 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.
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.
Checking/Changing Carbon Brushes:
A spare set of carbon brushes (Part No. 813514) 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 4) by turning in counter-
clockwise 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.
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.

5. Handpiece Overload Protection:
If the Handpiece is used in an overload condition caused by excessive workload, it will trigger the
overload circuit protector. The red overload light will come on with an audible alarm, and the hand-
piece will stop. Immediately turn off control by putting the Power ON/OFF switch in OFF position.
Put power switch in ON position again when overload condition is corrected. There may be a time
delay of several seconds before the overload trip resets.
6. Fuse Protection:
The internal circuit is protected by a 3.15 Amp,
5mm x 20mm, Bussman Type GDC-3.15A or equiv-
alent fuse. A blown fuse usually indicates a short
circuit condition on the circuit board. The blown
fuse should require that the board be checked by
a qualified technician. Disconnect the power cord,
unscrew the four feet and remove the baseplate.
The fuse is located in the top left corner of the cir-
cuit board. Replace fuse and re-assemble the
baseplate with four feet.
Re-connect the Power cord and test unit operation.
