designed for the selected wheel.

 Wheels for 

which the power tool was not designed cannot be 
adequately guarded and are unsafe.

r. 

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.

s. 

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.

t. 

Always use undamaged wheel flanges that are 
of correct size and shape for your selected 
wheel.

 Proper wheel Ä anges support the wheel 

thus reducing the possibility of wheel breakage. 
Flanges for cut-off wheels may be different from 
grinding wheel Ä anges.

u. 

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.

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 power 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 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 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.

ADDITIONAL SAFETY WARNINGS SPECIFIC FOR 
GRINDING OPERATIONS

a.  Check that the speed marked on the grinding 

wheel is equal to or greater than the rated speed 
of the tool.

b.  Ensure that the dimensions of the grinding wheel 

are compatible with the tool and that the wheel Ì ts 
the spindle.

c.  Grinding wheels must be stored in a dry place.
d.  Do not store objects on top of the grinding wheels.
e. Grinding wheels must not be used for any 

operation other than grinding.

f.  Inspect the grinding wheel before use to ensure 

that it is not chipped or cracked. Chips or cracks 
can cause the wheels to shatter, resulting in 
possible serious injury.

g.  Ensure that the grinding wheel is correctly mounted 

and tightened before use and run the tool at no-
load speed for 30 seconds in a safe position. Stop 
immediately if there is considerable vibration or if 
other defects are detected. If this condition occurs, 
check the tool to determine the cause.

h.  Do not use separate reducing bushings or adapters 

to adapt large hole grinding wheels.

i.  Check that the workpiece is properly supported.
j.  Ensure that sparks resulting from use do not create 

a hazard e.g. do not hit people, or ignite Ä ammable 
substances.

k.  Always use protective safety glasses and ear 

protectors.

l.  Use other personal protective equipment such as 

gloves, apron and helmet when necessary.

m.  Never place the tool on the Ä oor or other surfaces 

while it is running. Grinding wheels continue to 
rotate after the tool is switched off. Never touch 
the wheel or place it on the Ä oor or other surfaces 
while it is rotating.

n.  The Ä ange and clamp nut must have same outer 

diameter.

o.  Use the tool only for approved applications. Never 

use coolants or water or use the tool as a Ì xed
