OPERATION
WARNING:
It should never be necessary to
force the tool. The weight of the tool applies ade -
quate pressure. Forcing and excessive pressure
could cause dangerous wheel breakage.
WARNING:
ALWAYS replace wheel if tool is
dropped while grinding.
WARNING:
NEVER bang or hit grinding disc
or wheel onto work.
WARNING:
Avoid bouncing and snagging
the wheel, especially when working corners,
sharp edges etc. This can cause loss of control and
kickback.
WARNING:
NEVER use tool with wood cutting
blades and other saw blades.
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.
CAUTION:
Always wear safety goggles or a
face shield during operation.
CAUTION:
After operation, always switch off
the tool and wait until the wheel has come to a
complete stop before putting the tool down.
CAUTION:
ALWAYS hold the tool firmly with
one hand on housing and the other on the side
grip (handle).
Grinding and sanding operation
► Fig.17
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° to the workpiece surface.
During the break-in period with a new wheel, do not
work the grinder in forward direction or it may cut into
the workpiece. Once the edge of the wheel has been
rounded off by use, the wheel may be worked in both
forward and backward direction.
Operation with abrasive cut-off /
diamond wheel
Optional accessory
WARNING:
When using an abrasive cut-off
/ diamond wheel, be sure to use only the special
wheel guard designed for use with cut-off wheels.
(In some European countries, when using a diamond
wheel, the ordinary guard can be used. Follow the
regulations in your country.)
WARNING:
NEVER use cut-off wheel for side grinding.
WARNING:
Do not "jam" the wheel or apply
excessive pressure. Do not attempt to make an exces -
sive depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or binding of the
wheel in the cut and the possibility of kickback, wheel
breakage and overheating of the motor may occur.
WARNING:
Do not start the cutting operation in
the workpiece. Let the wheel reach full speed and care -
fully enter into the cut moving the tool forward over
the workpiece surface. The wheel may bind, walk up or
kickback if the power tool is started in the workpiece.
WARNING:
During cutting operations, never
change the angle of the wheel. Placing side pressure
on the cut-off wheel (as in grinding) will cause the wheel
to crack and break, causing serious personal injury.
WARNING:
A diamond wheel shall be oper -
ated perpendicular to the material being cut.
Mount the inner flange onto the spindle.
Fit the wheel / disc on the inner flange and screw the
lock nut onto the spindle.

Operation with wire cup brush
Optional accessory
CAUTION:
Check operation of brush by run -
ning tool with no load, insuring that no one is in
front of or in line with brush.
CAUTION:
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.20: 1. Wire cup brush
Remove the battery cartridge and place the tool upside
down allowing easy access to spindle.
Remove any accessories on spindle. Thread wire cup
brush onto spindle and tighten with supplied wrench.
NOTICE:
Avoid applying too much pressure
which causes over bending of wires when using
brush. It may lead to premature breakage.
