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.

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.

cord. Cutting accessory contacting a “live” wire may make exposed metal parts of 

the power tool “live” and shock the operator. 

j)  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.

k)  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.

l)  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.

m)  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.

n) do not operate the power tool near flammable materials. Sparks could ignite 

these materials.

o) do not use accessories that require liquid coolants. Using water or other liquid 

coolants may result in electrocution or shock.

p) do not use Type 11 (flaring cup) wheels on this tool. Using inappropriate  

accessories can result in injury.

q) Always use auxiliary handle. Tighten the handle securely. The auxiliary 

handle should always be used to maintain control of the tool at all times.

   r)  use clamps or another practical way to secure and support the work piece 

to a stable platform. Holding the work by hand or against your body leaves it 

unstable and may lead to loss of control.

   s) When starting the tool with a new or replacement wheel, or a new or 

it run for one minute. If the wheel has an undetected crack or flaw, it should burst 

in less than one minute. If the wire brush has loose wires, they will be detected. 

Never start the tool with a person in line with the wheel. This includes the operator.

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 tool misuse and/or incorrect operating procedures or  

conditions and can be avoided by taking proper precautions as given below:

maximum control over kickback or torque reaction during start up. The operator 

can control torque reaction or kickback forces, if proper precautions are taken.

b) Never place your hand near the rotating accessory. Accessory may kickback 

over your hand.

kickback occurs. Kickback will propel the tool in direction opposite to the wheel’s 

movement at the point of snagging.

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.
