5) Service

a) Have your power tool serviced by a qualified repair

person using only identical replacement parts.

This will ensure that the safety of the power tool

is maintained.

PRECAUTION

Keep children and infirm persons away.

When not in use, tools should be stored out of reach of

children and infirm persons.

CUT-OFF MACHINE SAFETY WARNINGS

a) 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 operator. Position yourself and

bystanders away from the plane of the rotating

wheel.

The guard helps to protect operator from broken

wheel fragments and accidental contact with wheel.

b) 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.

c) 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.

d) 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.

e) 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.

f) 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.

g) 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.

h) 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.

i) Wear personal protective equipment. Depending on

application, use face shield, safety goggles or safety

glasses. As appropriate, wear dust mask, hearing

protectors, gloves and shop apron capable of

stopping small abrasive or workpiece fragments.

The eye protection 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.

j) 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.

k) Hold the power tool by insulated gripping surfaces

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 electric shock.

l) 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.

m) 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.

n) 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.

o) 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.

p) Do not operate the power tool near flammable

materials.

Sparks could ignite these materials.

q) 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.

a) 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.
