 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.

KICKBACK AND RELATED WARNINGS:

Kickback is a sudden reaction to a pinched or snagged rotat-

ing wheel. Pinching or snagging causes rapid stalling of the

rotating wheel which in turn causes the uncontrolled power

tool to be forced in the direction opposite of the wheel’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:

 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.

 Never place your hand near the rotating accessory.

Accessory may kickback over your hand.

 Do not position your body in line with the rotating

wheel. Kickback will propel the tool in direction opposite

to the wheel’s movement at the point of snagging.

 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 saw chain, woodcarving blade,

segmented diamond wheel or toothed saw blade.

Such blades create frequent kickback and loss of control.

 Do not “jam” the 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.

 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 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.

 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.

ADDITIONAL SAFETY RULES

 Know your power tool. Read operator’s manual

carefully. Learn its applications and limitations, as well

as the specific potential hazards related to this tool.

Following this rule will reduce the risk of electric shock,

fire, or serious injury.

 Always wear eye protection with side shields marked

to comply with ANSI Z87.1. Failure to do so could

result in objects being thrown into your eyes, resulting in

possilbe serious injury.

 Protect your lungs. Wear a face or dust mask if the

operation is dusty. Following this rule will reduce the

risk of serious personal injury.

 Protect your hearing. Wear hearing protection during

extended periods of operation. Following this rule will

reduce the risk of serious personal injury.

 Inspect tool cords periodically and, if damaged, have

repaired at your nearest authorized service center.

Constantly stay aware of cord location. Following this

rule will reduce the risk of electric shock or fire.

 To reduce the risk of electrocution, keep all connec-

tions dry and off the ground. Keep the tool dry when

applying water to the cutting wheel. Do not stand in water

when operating the tool. Do not touch the plug with wet

hands. Keep bystanders away from water and electricity.
