Operation
Hold the tool firmly, 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°-30° 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
directions. (

)
WARNING:
It should never be necessary to force the tool. The weight of the tool applies
adequate pressure. Forcing and excessive pressure could cause dangerous
wheel breakage.
Continued use of a worn-out wheel may result in wheel explosion and serious
personal injury. Depressed center wheel should not be used after it has been
worn down to 75 mm (3
”) in diameter. Use of the wheel after this point is unsafe
and it should be removed from service and rendered unusable by intentional
destruction.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and unplugged before attempting to
perform inspection or maintenance.
After use

Replacing carbon brushes
Remove and check the carbon brushes
regularly. Replace when they wear down to
the limit mark. 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. (
