Operation
(Fig.
7)
CAUTION:
After operation, always switch off the machine and
wait until the wheel has come to a complete stop
before putting the machine down.
Hold the machine firmly. Turn the machine 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 machine 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 machine.
The weight of the machine applies adequate pres-
sure. 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 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 machine is switched off and
unplugged before carrying
out
any work on the
machine.
Replacement of carbon brushes (Fig. 6 & 9)
When the resin insulating tip inside the carbon brush
is exposed to contact the commutator, it will automati-
cally shut
off
the motor. When this occurs, both
carbon brushes should be replaced at the same time.
Use only identical carbon brushes.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
