Installing or removing dust cover attachment
(Optional accessory)
WARNING:
•
Always be sure that the tool is switched off and
unplugged before installing or removing the dust
cover attachment. Failure to do so causes damage
to the tool or a personal injury.
There are three types of dust cover attachment and
each is used in one of different positions.

Fig.13
Fig.14
Place the dust cover attachment so that the side of the
dust cover attachment with the marking (A,B or C) faces
towards the tool head. Snap the pins of the dust cover
attachment in the vent.
Fig.15
Dust cover attachment can be removed by hand.
NOTE:
•
Clean out the dust cover attachment when it is
clogged with dust or foreign matters. Continuing
operation with a clogged dust cover attachment
will damage the tool.
OPERATION
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.
•
ALWAYS replace wheel if tool is dropped while
grinding.
•
NEVER bang or hit grinding disc or wheel onto work.
•
Avoid bouncing and snagging the wheel,
especially when working corners, sharp edges etc.
This can cause loss of control and kickback.
•
NEVER use tool with wood cutting blades and
other sawblades. Such blades when used on a
grinder frequently kick and cause loss of control
leading to personal injury.
CAUTION:
•
After operation, always switch off the tool and wait
until the wheel has come to a complete stop
before putting the tool down.
Grinding and sanding operation
ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. 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 degrees 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 direction.

Operation with wire cup brush /
wire bevel brush (optional accessory)
CAUTION:
•
Check operation of brush by running tool with no load,
insuring that no one is in front of or in line with brush.
•
Do not use brush that is damaged, or which is out of
balance. Use of damaged brush could increase
potential for injury from contact with broken brush wires.
