position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control
over kickback or torque reaction during start-
up. The operator can control torque reactions or

d) Use special care when working corners, sharp
edges, etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory

ADDITIONAL SAFETY INSTRUCTIONS FOR GRINDING
AND CUTTING-OFF OPERATIONS
6DIHW\ ZDUQLQJV VSHFL¿F IRU JULQGLQJ DQG DEUDVLYH
cutting-off operations:
a) Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
b) The grinding surface of centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that

be adequately protected.
c) The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed
towards the operator. The guard helps to protect

could ignite clothing.
d) Wheels must be used only for recommended
applications. For example: Do not grind with
the side of cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
e) Always use undamaged wheel flanges that are
of correct size and shape for your selected
wheel. Proper wheel flanges support the wheel,

Flanges for cut-off wheels may be different from
grinding wheel flanges.
f) Do not use worn down wheels from larger
power tools. Wheel intended for larger power tool
is not suitable for the higher speed of a smaller tool
and may burst.
ADDITIONAL SAFETY WARNINGS SPECIFIC FOR
ABRASIVE CUTTING-OFF OPERATIONS
a) Do not “jam” the cut-off wheel or apply
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

b) Do not position your body in line with and
behind the rotating wheel. When the wheel,
at the point of operation, is moving away from

spinning wheel and the power tool directly at you.
c) When wheel is binding or when interrupting a
cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never attempt
to remove the cut-off wheel from the cut while
the wheel is in motion otherwise kickback may
occur.

eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind,
