disc at an angle of about
15O tothe work-
piece surface.
Duringthe break-inperiodwitha new wheel,
do notwork thegrinder
in the Bdirection or
it will cut intothe workpiece. Oncethe 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
1 15 mm (4-1 12") 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.
Replacingcarbon 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 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 securethe
