f. Do not use worn down reinforced wheels from larger
power tools.
Wheels intended for a larger power tool are
not suitable for the higher speed of a smaller tool and may
burst.
g. The outside diameter and the thickness of your
accessory must be within the capacity rating of your
power tool.
Incorrectly sized accessories cannot be
adequately guarded or controlled.
h. The arbour size of wheels and fl anges must properly fi t
the spindle of the power tool. Wheels and fl anges with
arbour holes that do not match the mounting hardware of
the power tool will run out of balance, vibrate excessively,
and may cause loss of control.
i. 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.
j. Wear personal protective equipment. Depending
on application, use face shield, safety 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 fl ying
debris generated by various operations. The dust mask or
respirator must be capable of
fi ltrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
k. 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 fl y 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 accessory. If
you lose control, the cord may be cut or snagged and your
hand or arm may be pulled into the spinning accessory.
n. Never lay the power tool down until the accessory 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 powdered metal may cause electrical
hazards.
q. Do not operate the power tool near fl ammable
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.

operations
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotating
wheel. Pinching or snagging causes 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 incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
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 kickback
forces, if proper precautions are taken.
b. Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c. Do not position your body in line with the rotating
wheel.
Kickback will propel the product 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 snagging the accessory.
Corners, sharp edges, or bouncing have a tendency 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 peripheral 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 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 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 attempt 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 workpiece 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 kickback.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
The rated speed of the accessory must be at least equal to the
maximum speed marked on the power tool.
Accessories running faster than their rated speed can break
and
fl y apart.
