Makita N900 Grinder User Manual


 
Operation
Hold the tool firmly. Turn the tool on and wait
until the wheel or disc attains full speed.
Then apply the wheel or disc to the work-
piece. In general, keep the edge of the wheel
or disc at an angle of about
15'
to the work-
piece 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.
Abrasive disc (optional accessory)
