Replacing Carbon Brushes; Accessories - Makita GA7020 Betriebsanleitung

Grinding and sanding operation (Fig. 8)
ALWAYS hold the tool firmly with one hand on rear handle
and the other on the side handle. Turn the tool on and
then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an angle
of about 15 degrees to the workpiece surface.
During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the
workpiece. Once the edge of the wheel has been rounded
off by use, the wheel may be worked in both A and B
direction.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
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. (Fig. 9)

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. (Fig. 10)
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. (Fig. 11)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
