10. Hold the power tool by insulated gripping sur-

faces 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 could give the operator an elec-

tric shock.

11. Position the cord clear of the spinning acces-

sory. 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 acces-

sory 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 cool-

ants. 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 acces-

sory. 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 mate-

rial 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 incor-

rect 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 posi-

tion your body and arm to allow you to resist kick-

back 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 acces-

sory. 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 towards

the operator. The guard helps to protect the operator

from broken wheel fragments, accidental contact with

wheel and sparks that could ignite clothing.

c) Wheels must be used only for recommended

applications. For example: do not grind with the

side of cut-off wheel. Abrasive cut-off wheels are

intended for peripheral grinding, side forces applied

to these wheels may cause them to shatter.

d) Always use undamaged wheel flanges that are of

correct size and shape for your selected wheel.

Proper wheel flanges support the wheel thus reduc-

ing the possibility of wheel breakage. Flanges for cut-

off wheels may be different from grinding wheel

flanges.

e) Do not use worn down wheels from larger power

tools. Wheel intended for larger power tool is not

suitable for the higher speed of a smaller tool and

may burst.

Additional Safety Warnings Specific for Abrasive

Cutting-Off Operations:

a) Do not “jam” the 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 binding of the

wheel in the cut and the possibility of kickback or

wheel breakage.

b) Do not position your body in line with and behind

the rotating wheel. When the wheel, at the point of

operation, is moving away from your body, the possi-

ble kickback may propel the spinning wheel and the

power tool directly at you.

c) 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

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 binding.

d) Do not restart the cutting operation in the work-

piece. Let the wheel reach full speed and care-

fully re-enter the cut. The wheel may bind, walk up

or kickback if the power tool is restarted in the work-

piece.

e) 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.
