h. Wheels and flanges with arbour holes that
do not match the mounting hardware of the
power tool will run out of balance, vibrate ex-
cessively and may cause loss of control. Do
not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If
power tool or wheel is dropped, inspect for
damage or install an undamaged wheel. After
inspecting and installing the wheel, position
yourself and bystanders away from the plane
of the rotating wheel and run the power tool at
maximum no load speed for one minute.
Damaged wheels will normally break apart during
this test time.
i. Wear personal protective equipment. De-
pending on application, use face shield, safe-
ty goggles or safety glasses. As appropriate,
wear dust mask, hearing protectors, gloves
and shop apron capable of stopping small
abrasive or workpiece fragments.
The eye protection must be capable of stopping fly-
ing debris generated by various operations. The dust
mask or respirator must be capable of filtrating par-
ticles generated by your operation. Prolonged expo-
sure to high intensity noise may cause hearing loss.
j. Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken wheel may
fly away and cause injury beyond immediate area
of operation.
k. Keep the power cable away from rotating in-
sertion tools.
If you lose control of the device, the power cable
can be severed or caught and your arm pulled into
the rotating insertion tool.
Regularly clean the power tool's air vents.
l.
The motor's fan will draw the dust inside the hous-
ing and excessive accumulation of powdered met-
al may cause electrical hazards.
m. Do not operate the power tool near flammable
materials. Do not use the electrical tool if it is
on a flammable surface such as wood.
Sparks could ignite these materials.
n. Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may result in
electrocution or shock.
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.
LEROY MERLIN • Rue Chanzy - Lezennes 59712 Lille Cedex 9 - FRANCE
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 po-
sition your body and arm to allow you to resist
kickback forces.
The operator can control torque reactions or kick-
back forces, if proper precautions are taken.
b. 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.
c. Never use a chain, wood cutting or toothed
saw blade, or any segmented diamond grind-
ing wheel with gaps of more than 10 mm.
Such blades create frequent kickback and loss of
control.
d. 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.
e. 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.
f. 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.
g. Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back.
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.
