Makita 90471 Grinder User Manual


 
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 15O 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.

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
115
mm
(4-1/2") in diameter.
Use
of the wheel after this point is unsafe and
it
should
be removed from service and rendered unusable by intentional destruction.
