MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
The tool and its air vents have to be kept clean. Regularly
clean the tool’s air vents or whenever the vents start to
become obstructed.

Replacing carbon brushes (Fig. 16)
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.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.

To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
