Maintenance - Makita GA7030 Instruction Manual

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
breakage 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
workpiece surface. The wheel may bind, walk up
or kickback 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 perpendicular
•
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 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.
