6. 

The arbour size of wheels, flanges, backing 
pads or any other accessory must properly fit 
the spindle of the power tool.

 Accessories with 

arbour holes that do not match the mounting 
hardware of the power tool will run out of balance, 
vibrate excessively and may cause loss of control. 

7. 

Do not use a damaged accessory. Before each 
use inspect the accessory such as abrasive 
wheels for chips and cracks, backing pad for 
cracks, tear or excess wear, wire brush for 
loose or cracked wires. If power tool or 
accessory is dropped, inspect for damage or 
install an undamaged accessory. After 
inspecting and installing an accessory, 
position yourself and bystanders away from 
the plane of the rotating accessory and run the 
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 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 
shock the operator. 

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 guard must be securely attached to the 

power tool and positioned for maximum safety, 
so the least amount of wheel is exposed
