FOR ALL OPERATIONS
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 snagging 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 tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below:
♦
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 reaction or kickback forces, if proper precautions
are taken.
♦
Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
♦
Do not position your body in the area where
power tool will move if kickback occurs.
Kickback
will propel the tool in direction opposite to the wheel’s
movement at the point of snagging.
♦
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.
♦
Do not attach a saw chain woodcarving blade
or toothed saw blade.
Such blades create frequent
kickback and loss of control.
SAFETY WARNINGS SPECIFIC
FOR GRINDING OPERATIONS
♦
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.
♦
The grinding surface of 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.
♦
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 operator from
broken wheel fragments and accidental contact with
wheel and sparks that could ignite clothing.
♦
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.
♦
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.
♦
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 OPERATIONS
Do not “jam” the cutting blade or apply excessive
pressure.
Do not attempt to make a cut of excessive
depth. Tension overload on the blade increases the load
and the possibility that the blade may twist or jam during
cutting and produce recoil or break the blade. This can
be avoided by taking the proper precautions listed below:
♦
Hold the power tool firmly and place your body
and arm so as to withstand the recoil forces.
Always use the side handle, if available, for maximum
control over the recoil or torque reaction during start
up. The operator can control torque reaction or recoil
forces if proper precautions are taken.
♦
When the blade becomes jammed or when a cut
is interrupted for any reason, unplug and hold the
power tool until the blade stops completely. Never
attempt to remove the cutting blade while it is in
motion, because this may cause recoil.
Investigate
and take corrective action to eliminate the cause of the
blade jamming.
♦
Do not restart the cutting operation on the
workpiece. Allow the blade to reach full speed
and try to cut again carefully.
The blade can get
jammed, jump or recoil if the power tool is restarted
on the workpiece.
♦
Support panels or any larger workpiece to
reduce the risk of compression and recoil. Large
workpieces tend to sag under their own weight.
Supports must be placed under the workpiece, near the
cutting line and near the edge of the workpiece, on both
sides of the blade.
♦
Use extreme caution when performing a “hollow
cut” into existing walls or other hidden areas.
The
protruding blade may cut gas or water lines, electrical
wiring or objects that can cause recoil.
SPECIFIC SAFETY INSTRUCTIONS FOR SANDING
♦
Do not use excessively large sanding discs. Follow
the manufacturer’s recommendations when
selecting the sandpaper.
The largest sandpaper,
which extends beyond the sanding pad presents a
laceration hazard and may cause snagging or tearing
of the disc or recoil.
