power tool at maximum no-load speed for one 
minute.

 Damaged accessories will normally 

break apart during this test time. 

8. 

Wear personal protective equipment. 
Depending on application, use face shield, 
safety goggles or safety glasses. As 
appropriate, wear dust mask, hearing 
protectors, gloves and workshop apron 
capable of stopping small abrasive or 
workpiece fragments.

 The eye protection must 

be capable of stopping flying debris generated by 
various operations. The dust mask or respirator 
must be capable of filtrating particles generated 
by your operation. Prolonged exposure to high 
intensity noise may cause hearing loss. 

9. 

Keep bystanders a safe distance away from 
work area. Anyone entering the work area 
must wear personal protective equipment.

Fragments of workpiece or of a broken accessory 
may fly away and cause injury beyond immediate 
area of operation. 

10. 

Hold the power tool by insulated gripping 
surfaces only, when performing an operation 
where the cutting accessory may contact 
hidden wiring or its own cord.

 Cutting 

accessory contacting a "live" wire may make 
exposed metal parts of the power tool "live" and 
could give the operator an electric shock. 

11. 

Position the cord clear of the spinning 
accessory.

 If you lose control, the cord may be 

cut or snagged and your hand or arm may be 
pulled into the spinning accessory.   

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 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.
