MAINTENANCE

Preventative maintenance

performed by unautho-

rized personnel may result in misplacing

of internal wires and components which

could cause serious hazard. We recom-

mend that all tool service be performed by

a Dremel™ Service Facility.

To avoid injury from unex-

pected starting or electri-

cal shock, always remove plug from wall

outlet before performing service or

cleaning.

Carbon Brushes

The brushes in your tool have been engi-

neered for many hours of dependable serv-

ice.
To prepare the brushes for use, run the tool

at full speed for 5 minutes under no load.

This will properly “seat” the brushes, and

extend the life of the tool.
To maintain peak efficiency of the motor,

examine the brushes for wear every 40-50

hours.

Using the tool with worn

brushes will permanently

damage the motor.
Use only original Dremel™ replacement

brushes.’
Inspect the rotary tool brushes after 40-50

hours of use. If the rotary tool runs erratical-

ly, loses power, or makes unusual noises

check the brushes for wear and possible

replacement. Remember: brushes in the

rotary tool are similar to oil in a car; the more

you check/service, the better the perform-

ance.
Follow these steps to check/change the rotary

tool brushes:
1 With the power cord unplugged, place

the tool on a clean surface. Use the tool

wrench as a screwdriver to remove the

brush caps in a counter-clockwise

direction (Figure A).

2. Remove the brushes from the tool by

pulling on the spring that is attached to

the carbon brush. If the brush is less

than 1/8” long and the surface of the

brush that touches the commutator is

rough or pitted, the carbon brushes

should be replaced. Be sure to check

both brushes (Figure B).

3. If one brush is worn, you should replace

both brushes for better performance of

your rotary tool. Remove the spring

from the brush, throw away the old

brush and place the spring on a new

brush.
