Hold the tool firmly with both hands. Turn the tool on
and apply slight pressure on the tool so that the tool will
not bounce around, uncontrolled. Pressing very hard on
the tool will not increase the efficiency.

•
unplugged before attempting to perform inspection
or maintenance.

•
the like. Discoloration, deformation or cracks may
result.

Replacing carbon brushes

When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced. Keep the carbon brushes
clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
