Installing offset diamond wheel
Optional accessory
With optional accessories, you can use this tool for
planing concrete surface.
WARNING:
For offset diamond wheels that
are 7 mm or thinner, place the convex section of
the lock nut upwards and attach to the spindle.
CAUTION:
Dust collecting wheel guard for the offset
diamond wheel is only for use in planing concrete surface
with a offset diamond wheel. Do not use this guard with
any other cutting accessory or for any other purpose.
CAUTION:
Before operation, make sure that a
vacuum cleaner is connected to the tool and turned on.
Remove the battery cartridge and install the dust col-
lecting wheel guard for the offset diamond wheel.
Mount the inner flange onto the spindle. Fit the offset diamond
wheel on the inner flange and tighten the lock nut onto the spindle.

Connecting a vacuum cleaner
Optional accessory
WARNING:
Never vacuum metal particles cre-
ated by grinding/cutting/sanding operation. Metal
particles created by such operation are so hot that they
ignite dust and the filter inside the vacuum cleaner.
To avoid dusty environment caused by masonry cutting,
use a dust collecting wheel guard and a vacuum cleaner.
Refer to the instruction manual attached to the dust
collecting wheel guard for assembling and using it.

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.25
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:
excessive pressure. Do not attempt to make an
excessive 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:
in the workpiece. Let the wheel reach full speed
and carefully 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:
change the angle of the wheel. Placing side pres-
sure on the cut-off wheel (as in grinding) will cause
the wheel to crack and break, causing serious per-
sonal injury.
WARNING:
ated perpendicular to the material being cut.
