Optional Accessories - Makita GA7020R Bedienungsanleitung

► Fig.15: 1. Wire cup brush
Unplug tool and place it upside down allowing easy access to
spindle. Remove any accessories on spindle. Mount wire cup
brush onto spindle and tighten with supplied wrench. When
using brush, avoid applying too much pressure which causes
over bending of wires, leading to premature breakage.
Operation with wire wheel brush
(optional accessory)
CAUTION:
• Check operation of wire wheel brush by running
tool with no load, insuring that no one is in front
of or in line with the wire wheel brush.
• Do not use wire wheel brush that is damaged,
or which is out of balance. Use of damaged wire
wheel brush could increase potential for injury
from contact with broken wires.
• ALWAYS use guard with wire wheel brushes,
assuring diameter of wheel fits inside guard.
Wheel can shatter during use and guard helps
to reduce chances of personal injury.
► Fig.16: 1. Wire wheel brush
Unplug tool and place it upside down allowing easy access
to spindle. Remove any accessories on spindle. Thread wire
wheel brush onto spindle and tighten with the wrenches.
When using wire wheel brush, avoid applying too much
pressure which causes over bending of wires, leading
to premature breakage.
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 European countries, when using
a diamond wheel, the ordinary guard can be used.)
• 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.
► Fig.19: 1. Exhaust vent 2. Inhalation vent
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.20: 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.
► Fig.21: 1. Brush holder cap 2. Screwdriver
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.
