l) Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may grab the
surface and pull the power tool out of your control.
m) 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.
n) 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.
o) Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
p) 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, backing pad, brush or any other accessory. Pinching or snag-
ging causes rapid stalling of the rotating accessory which in turn
causes the uncontrolled power tool to be forced in the direction
opposite of the accessory’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 opera-
ting 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 the area where power tool
will move if kickback occurs. Kickback will propel the tool in di-
rection 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 or toothed
saw blade.
Such blades create frequent kickback and loss of control.
toothed saw blade.
Safety Warnings Specific for Grinding and Abrasive 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 the centre depressed wheels must
be mounted below the plane of the guard lip. An improperly
mounted wheel that projects through the plane of the guard lip
cannot 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 the operator from broken wheel fragments, accidental
contact with wheel and sparks that 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 thus reducing the possibility of wheel breakage.
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 of kickback or wheel
breakage.
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 your body, the possible kickback may propel the 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.
Investigate
and take corrective action to 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, walk up or kickback if the power tool is restarted in
the workpiece.
e) 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.
f) 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.
Safety Warnings Specific for Sanding Operations:
a) Do not use excessively oversized sanding disc paper.
Follow manufacturers recommendations, when selecting
sanding paper. Larger sanding paper extending beyond the
sanding pad presents a laceration hazard and may cause snagging,
tearing of the disc or kickback.
Safety Warnings Specific for Wire Brushing Operations:
a) Be aware that wire bristles are thrown by the brush
even during ordinary operation. Do not overstress the wires
by applying excessive load to the brush.
The wire bristles can
easily penetrate light clothing and/or skin.
b) If the use of a guard is recommended for wire brushing,
