■

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.

■

Do not operate the power tool near flammable 
materials.

 Sparks could ignite these materials.

■

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, sanding band, 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.
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.

■

Maintain a firm grip on the power tool and position 
your body and arm to allow you to resist kickback 
forces. 

The operator can control kickback forces, if 

proper precautions are taken.

■

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.

■

Do not attach a toothed saw blade. 

Such blades 

create frequent kickback and loss of control.

■

Always feed the bit into the material in the same 
direction as the cutting edge is exiting from the 
material (which is the same direction as the chips 
are thrown). 

Feeding the tool in the wrong direction 

causes the cutting edge of the bit to climb out of the 
work and pull the tool in the direction of this feed. 

■

When using rotary files, cut-off wheels, high-speed 
cutters or tungsten carbide cutters, always have 
the work securely clamped. 

These wheels will grab 

if they become slightly canted in the groove, and can 
kickback. When a cut-off wheel grabs, the wheel itself 
usually breaks. When a rotary file, high-speed cutter 
or tungsten carbide cutter grabs, it may jump from the 
groove and you could lose control of the tool.

Safety warnings speci

fi

 c for grinding and abrasive 

cutting-off operations

■

Use only wheel types that are recommended 
for your power tool and only for recommended 
applications. For example: do not grind with the 
side of a cut-off wheel. 

Abrasive cut-off wheels are 

intended for peripheral grinding, side forces applied to 
these wheels may cause them to shatter.

■

For threaded abrasive cones and plugs use only 
undamaged wheel mandrels with an unrelieved 
shoulder flange that are of correct size and length. 

Proper mandrels will reduce the possibility of breakage.

■

Do not “jam” a 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 snagging of the 
wheel in the cut and the possibility of kickback or wheel 
breakage.

■

Do not position your hand in line with and behind 
the rotating wheel. 

When the wheel, at the point of 

operation, is moving away from your hand, the possible 
kickback may propel the spinning wheel and the power 
tool directly at you.

■

When wheel is pinched, snagged 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 pinching or snagging.

■

Do not restart the cutting operation in the workpiece. 
Let the wheel reach full speed and carefully re-enter 
the cut. 

The wheel may bind, walk up or kickback if the 

power tool is restarted in the workpiece.

■

Support panels or any oversized workpiece to 
minimize the risk of wheel pinching and kickback.

Large workpieces tend to sag under their own weight. 
Supports must be placed under the workpiece near the 
line of cut and near the edge of the workpiece on both 
sides of the wheel.

■

Use extra caution when making a “pocket cut” into 
existing walls or other blind areas.

 The protruding 

wheel may cut gas or water pipes, electrical wiring or 
objects that can cause kickback.

Safety warnings speci

fi

 c for wire brushing operations

■

Be aware that wire bristles are thrown by the brush 
even during ordinary operation. Do not overstress 
the wires by applying excessive load to the brush. 

The wire bristles can easily penetrate light clothing and/
or skin.

■

Allow brushes to run at operating speed for at least 
one minute before using them. During this time no 
one is to stand in front or in line with the brush. 

Loose bristles or wires will be discharged during the 
run-in time.

■

Direct the discharge of the spinning wire brush 
away from you.

 Small particles and tiny wire fragments 

may be discharged at high velocity during the use of 
these brushes and may become imbedded in your skin. 

ADDITIONAL SAFETY WARNINGS

■

Inspect for and remove all nails from the workpiece 
before using the product.

 Following this rule will 

reduce the risk of serious personal injury.

■

Do not reach in the area of the spinning bit.

 The 

proximity of the spinning bit to your hand may not 
always be obvious.
