Replacing Carbon Brushes; Optional Accessories - Makita GA7010C Bedienungsanleitung

Operation with abrasive cut-off /
diamond wheel (optional accessory)
WARNING:
• When using an abrasive cut-off / diamond
wheel, be sure to use only the special wheel
guard designed for use with cut-off wheels.(In
some European countries, when using a dia-
mond wheel, the ordinary guard can be used.
Follow the regulations in your country.)
• NEVER use cut-off wheel for side grinding.
• Do not "jam" the wheel or apply excessive pressure.
Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in
the cut and the possibility of kickback, wheel break-
age and overheating of the motor may occur.
• Do not start the cutting operation in the workpiece.
Let the wheel reach full speed and carefully enter
into the cut moving the tool forward over the work-
piece surface. The wheel may bind, walk up or kick-
back if the power tool is started in the workpiece.
• During cutting operations, never change the angle
of the wheel. Placing side pressure on the cut-off
wheel (as in grinding) will cause the wheel to crack
and break, causing serious personal injury.
• A diamond wheel shall be operated perpendicu-
lar to the material being cut.
Mount the inner flange onto the spindle. Fit the wheel/
disc on the inner flange and screw the lock nut onto the
spindle.

MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.

Replacing carbon brushes

► Fig.15: 1. Commutator 2. Insulating tip 3. Carbon
brush
When the resin insulating tip inside the carbon brush
is exposed to contact the commutator, it will automati-
cally 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 per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
