12. 

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. 

13. 

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.   

14. 

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. 

15. 

Do not operate the power tool near flammable 
materials.

 Sparks could ignite these materials. 

16. 

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 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 

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 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. 
c) 

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. 
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 of 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. 

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 reenter the cut.

 The wheel may bind, 

walk up or kickback if the power tool is restarted in 
the workpiece.
