the wheel thus reducing the possibility
of wheel breakage.
f) 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.
g) The arbour size of wheels and flanges
must properly fit the spindle of the power
tool. Wheels and flanges 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.
h) Do not use damaged wheels. Before each
use, inspect the wheels for chips and cracks. If
the 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.
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 flying
debris generated by various operations. The
dust mask or respirator must be capable of
filtrating particles generated by your operation.
Prolonged exposure 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) 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 wheel.
l) Regularly clean the power tool's air
vents. The motor's fan can draw the dust inside
the housing and excessive accumulation of
powdered metal may cause electrical hazards.
m) Do not operate the power tool near
flammable materials. Do not operate the
power tool while placed on a combustible
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.
Maintain a firm grip on the power tool
(3.1)
and position your body and arm to allow
you to resist kickback forces. The operator
can control upward kickback forces, if proper
precautions are taken.
b) Do not position your body in line with the

rotating wheel. If kickback occurs, it will
propel the cutting unit upwards toward the
operator.
c) Do not attach a saw chain, woodcarving
blade, segmented diamond wheel with a
peripheral gap greater than 10mm or
toothed saw blade. 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 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.
e) When the wheel is binding or when
interrupting a cut for any reason, switch
off the power tool and hold the cutting unit
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.
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 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.
Causes and operator
(3.2)
prevention of kickback:
Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the
workpiece toward the operator:
1. When the blade is pinched or bound
tightly by the kerf closing down, the blade
stalls and the motor reaction drives the unit
rapidly back toward the operator;
2. If the blade becomes twisted or
misaligned in the cut, the teeth at the
back edge of the blade can dig into the top
surface of the workpiece causing the blade
to climb out of the kerf and jump back
towards the operator.
Kickback is the result of saw misuse
(3.3)
and/or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below.
a) Maintain a firm grip with both hands on the
saw and position your arms to resist kickback
forces. Position your body to either side of the
blade, but not in line with the blade. Kickback
could cause the saw to jump backwards,
but kickback forces can be controlled by the
