area. Anyone entering the work area must wear

personal

protective

workpiece or of a broken wheel may fly away and cause

injury beyond immediate area of operation.

■

Hold the power tool by insulated gripping surfaces

only, when performing an operation where the

cutting accessory may contact hidden wiring.

Cutting accessory contacting a "live" wire may make

exposed metal parts of the power tool "live" and could

give the operator an electric shock.

■

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 wheel.

■

Never lay the power tool down until the accessory

has come to a complete stop. The spinning wheel

may grab the surface and pull the power tool out of your

control.

■

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.

■

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. 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

equipment.

Fragments

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 with a peripheral gap

greater than 10 mm 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.

■

Use slow steady pressure when cutting tile. Do not

force the product. Use of excessive pressure may

damage the motor.

■

Cutting tile for extended periods of time or cutting tile

longer than 30 cm could cause the saw to become

overheated. If this occurs, cool the saw by retracting

the wheel/blade into the guard, lifting the saw away

from the workpiece, and running the saw at full speed

for two minutes.
