CARBON BRUSH MAINTENANCE
The carbon brushes may require maintenance when the motor performance of
the tool decreases or stops working completely.
1. Remove the brush cap from the brush holder on each side of the motor
housing.
2. Remove the carbon brushes from the housing. Keep track of how the
carbon brushes are orientated during removal. The concave surface must
be oriented in the same way if the brushes are reused. This will prevent
unnecessary wear after reinstalling them.
3. Clean old carbon brushes before reinstalling them. Rub the contact areas
with a pencil eraser.
4. Reinsert the old carbon brushes in the same orientation to reduce wear.
5. Replace both carbon brushes if either is worn down more than 50 percent.
6. When installing the carbon brushes make sure the carbon portions of the
carbon brushes contact the motor armature and that the springs face
away from the motor. Also, make sure the springs operate freely.
7. Replace the brush caps. Do not overtighten.
IMPORTANT! New carbon brushes tend to spark when first used until
they wear and conform to the motor's armature.
CLEANING
• Wipe down exterior surfaces with a damp cloth to remove accumulated
dust.
DISPOSAL
Recycle a tool damaged beyond repair at the appropriate facility.
Contact your local municipality for a list of disposal facilities or by-laws for
electronic devices, batteries, oil or other toxic liquids.
