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
Fig.11
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)
Fig.12
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.
Unplug tool and place it upside down allowing easy
access to spindle. Remove any accessories on spindle.
Thread wire cup brush / wire bevel brush onto spindle
and tighten with supplied wrench. When using brush,
avoid applying too much pressure which causes over
bending of wires, leading to premature breakage.
