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:
•
Never switch on the tool when it is in contact with
the workpiece, it may cause an injury to operator.
•
Always wear safety goggles or a face shield during
operation.
•
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.16
ALWAYS hold the tool firmly with one hand on rear
handle 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
(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.
Fig.17
Unplug tool and place it upside down allowing easy
access to spindle. Remove any accessories on spindle.
Mount wire cup 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.
Operation with wire wheel brush
(optional accessory)
CAUTION:
•
Check operation of wire wheel brush by running
tool with no load, insuring that no one is in front of
or in line with the wire wheel brush.
•
Do not use wire wheel brush that is damaged, or
which is out of balance. Use of damaged wire
wheel brush could increase potential for injury
from contact with broken wires.
•
ALWAYS use guard with wire wheel brushes,
assuring diameter of wheel fits inside guard.
Wheel can shatter during use and guard helps to
reduce chances of personal injury.
