Further safety instructions for all

operations

Kickback and Related Warnings
Kickback is a sudden reaction to a

_inched or snagged rotating wheel,

acking pad, brush or any other

accessory. Pinching or snagging
causes rapid s_lling of the rotating

accessory which in turn causes the
uncontrolled power tool to be forced
in the direction opposite of the

acce_'s rotation at the pointol the
binding,

For example, i!an abrasive wheel is
snagged or pin_ by the wod<piece.

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
wheeAmay either jump toward or

away from the operator, depending
on direction of the wheel's movement

at the point of pinchmgoAbrasive
wheels may also break under these

conditions.
Kickback is the resu|t of tool misuse
andtor incorrect operating procedures

or conditions and can be avoided by
taking proper precautions as given

below:

a) Malntain a firm grip on the power

too! 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, ifproper

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 toot in direction opposite to
the whee!'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 rolatl"ngaccessory and cause/oss
ot control or kickback.

e) Do not attach a saw chain

woodcarving blade or toothed saw
blade. Such blades oreate frequent

kickback and loss of control,

Safety Warnings Specific for Grinding
Operations

a) Use only wheel types that are

recommended for your power too!

and the specific guard designed

for the selected wheel. Wheels for

which the power too_ was not

designed cannot be adequately

guarded and are unsate.

b) 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

a_cidentat contact wilfl wheel.

c) Wheels must be used only for

recommended applications. For

example: do not grind with the side

of wheel Abrasive wheels are

inter_ed for peripheral grinding, side

forces applied to these wheels may

cause them to shatter.

d) 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 ot

wheel breakage. Flanges for cut-off

wheels may be different from grinding

wheel flanges,

e) 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.

Safety Warnings Specific for Sanding
Operatlons

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,tearingol the disc or kickback.

Safety Warnings Specific for Wire
Brushing Operations

a) Be aware thal 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

dolhing andlor skin.

b) !f the use Of a guard Is recommended

for wire brushlng, do not allow any

Interference of the wlre wheel or
brush with the guard. Wire wheel or

txush may expand in diameter due to

work and centrifugal forces.
