o) Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may
result in electrocution or shock.
FURTHER SAFETY INSTRUCTIONS
FOR ALL OPERATIONS
Causes and Operator
Prevention of Kickback
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:
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
reaction 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 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
or toothed saw blade.
Such blades create frequent
kickback and loss of control.
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 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 operations, 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.
