SAFETY WARNINGS COMMON FOR

GRINDING OR ABRASIVE CUTTING-OFF

OPERATIONS

a) This power tool is intended to function as a grinder

or cut-off tool. Read all safety warnings, instructions,

illustrations and specifications provided with this

power tool.

Failure to follow all instructions listed below may

result in electric shock, fire and/or serious injury.

b) Operations such as sanding, wire brushing or

polishing are not recommended to be performed

with this power tool.

Operations for which the power tool was not

designed may create a hazard and cause personal

injury.

c) Do not use accessories which are not specifically

designed and recommended by the tool

manufacturer.

Just because the accessory can be attached to your

power tool, it does not assure safe operation.

d) 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.

e) 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.

f) The arbour size of wheels, flanges, backing pads

or any other accessory must properly fit the spindle

of the power tool.

Accessories 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.

g) Do not use a damaged accessory. Before each use

inspect the accessory such as abrasive wheels for

chips and cracks, backing pad for cracks, tear or

excess wear, wire brush for loose or cracked wires.

If power tool or accessory is dropped, inspect for

damage or install an undamaged accessory. After

inspecting and installing an accessory, position

yourself and bystanders away from the plane of

the rotating accessory and run the power tool at

maximum no-load speed for one minute.

Damaged accessories will normally break apart

during this test time.

h) Wear personal protective equipment. Depending on

application, use face shield, safety goggles or safety

glasses. As appropriate, wear dust mask, hearing

protectors, gloves and workshop 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.

i) 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 accessory

may fly away and cause injury beyond immediate

area of operation.

j) Hold 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

shock the operator.

k) 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 accessory.

l) Never lay the power tool down until the accessory

has come to a complete stop.

The spinning accessory may grab the surface and

pull the power tool out of your control.

m) 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.

n) 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.

o) Do not operate the power tool near flammable

materials.

Sparks could ignite these materials.

p) 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, backing pad, brush or any other accessory.

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 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.

The operator can control torque reactions or kickback

forces, if proper precautions are taken.

b) Never place your hand near the rotating accessory.

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.
