must wear personal protective equipment.
Fragments of workpiece or of a broken wheel
may fly away and cause injury beyond immediate
area of operation.
l) Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
m) Position the cord clear of the spinning acces-
sory.
If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning wheel.
n) Never lay the power tool down until the ac-
cessory has come to a complete stop.
The spinning wheel may grab the surface and
pull the power tool out of your control.
o) Do not run the power tool while carrying it at
your side.
Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory
into your body.
p) Regularly clean the power tool's air vents.
The motor's fan will draw the dust inside the
housing and excessive accumulation of pow-
dered metal may cause electrical hazards.
q) Do not operate the power tool near flamma-
ble materials.
Sparks could ignite these materials.
r) Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may result in
electrocution or shock.
FURTHER SAFETY INSTRUCTIONS FOR ABRA-
SIVE CUTTING-OFF OPERATIONS
Kickback and related warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel. Pinching or snagging caus-
es rapid stalling of the rotating wheel which in turn
causes the uncontrolled power tool to be forced in the
direction opposite of the wheel's rotation at the point
of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the surface
of the material causing the wheel to climb out or kick
out. The wheel may either jump toward or away from
the operator, depending on direction of the wheel's
movement at the point of pinching. Abrasive wheels
may also break under these conditions.
Kickback is the result of power tool misuse and/or in-
correct operating procedures or conditions and can
be avoided by taking proper precautions as given be-
low.

a) Maintain a firm grip on the power tool and
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 kick-
back forces, if proper precautions are taken.
b) Never place your hand near the rotating ac-
cessory.
Accessory may kickback over your hand.
c) Do not position your body in line with the ro-
tating wheel.
Kickback will propel the tool in direction opposite
to the wheel's movement at the point of snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and snag-
ging the accessory.
Corners, sharp edges or bouncing have a tenden-
cy to snag the rotating accessory and cause loss
of control or kickback.
e) Do not attach a saw chain, woodcarving
blade, segmented diamond wheel with a pe-
ripheral gap greater than 10 mm or toothed
saw blade.
Such blades create frequent kickback and loss of
control.
f) 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 or
wheel breakage.
g) 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 at-
tempt to remove the wheel from the cut while
the wheel is in motion otherwise kickback
may occur.
Investigate and take corrective action to eliminate
the cause of wheel binding.
h) 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, walk up or kickback if the
power tool is restarted in the workpiece.
i) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback.
Large workpieces tend to sag under their own
weight. Supports must be placed under the work-
piece near the line of cut and near the edge of the
workpiece on both sides of the wheel.
j) Use extra caution when making a "pocket
cut" into existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kick-
back.
