Cordless cutter safety warnings

The guard provided with the tool must be

securely attached to the power tool and

positioned for maximum safety, so the least

amount of wheel is exposed towards the oper-

ator. Position yourself and bystanders away

from the plane of the rotating wheel. The guard

helps to protect operator from broken wheel frag-

ments and accidental contact with wheel.

Use only diamond cut-off wheels for your

power tool. Just because an accessory can be

attached to your power tool, it does not assure

safe operation.

The rated speed of the accessory must be at

least equal to the maximum speed marked on

the power tool. Accessories running faster than

their rated speed can break and fly apart.

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.

Always use undamaged wheel flanges that are

of correct diameter for your selected wheel.

Proper wheel flanges support the wheel thus

reducing the possibility of wheel breakage.

The outside diameter and the thickness of your

accessory must be within the capacity rating

of your power tool. Incorrectly sized accessories

cannot be adequately guarded or controlled.

The arbour size of wheels and flanges must

properly fit the spindle of the power tool.

Wheels and flanges with arbour holes that do not

match the mounting hardware of the power tool

will run out of balance, vibrate excessively and

may cause loss of control.

Do not use damaged wheels. Before each

use, inspect the wheels for chips and cracks.

If power tool or wheel is dropped, inspect for

damage or install an undamaged wheel. After

inspecting and installing the wheel, position

yourself and bystanders away from the plane

of the rotating wheel and run the power tool

at maximum no load speed for one minute.

Damaged wheels will normally break apart during

this test time.

Wear personal protective equipment.

Depending on application, use face shield,

safety goggles or safety glasses. As appropri-

ate, wear dust mask, hearing protectors, gloves

and shop apron capable of stopping small

abrasive or workpiece fragments. The eye pro-

tection must be capable of 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.

10. Keep bystanders a safe distance away from

work area. Anyone entering the work area

must wear personal protective equipment.

Fragments of workpiece or of a broken wheel may

fly away and cause injury beyond immediate area

of operation.

11.

Hold the power tool by insulated gripping

surfaces only, when performing an operation

where the cutting accessory may contact hid-

den 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.

12. 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 wheel.

13. Never lay the power tool down until the acces-

sory has come to a complete stop. The spinning

wheel may grab the surface and pull the power

tool out of your control.

14. 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.

15. 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.

16. 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

rotating wheel. Pinching or snagging causes rapid stalling

of the rotating wheel which in turn causes the uncon-

trolled 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 move-

ment 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 kick-

back forces, if proper precautions are taken.

Never place your hand near the rotating acces-

sory. 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 with a peripheral

gap greater than 10 mm or toothed saw blade.

Such blades create frequent kickback and loss of

control.
