d. Store idle power tools out of the reach of children and do not

allow persons unfamiliar with the power tool or these instructions

to operate the power tool. Power tools are dangerous in the hands of

untrained users.

e. Maintain power tools. Check for misalignment or binding of

moving parts, breakage of parts and any other condition that may

affect the power tools operation. If damaged, have the power tool

repaired before use. Many accidents are caused by poorly maintained

power tools.

f. Keep cutting tools sharp and clean. Properly maintained cutting

tools with sharp cutting edges are less likely to bind and are easier to

control.

g. Use the power tool, accessories and tool bits etc., in accordance

with these instructions, taking into account the working conditions

and the work to be performed. Use of the power tool for operations

different from those intended could result in a hazardous situation.

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.

MULTITOOL SAFETY WARNINGS

SAFETY WARNINGS COMMON FOR

GRINDING, SANDING, WIRE BRUSHING,

POLISHING, CARVING OR ABRASIVE CUTTING-

OFF OPERATIONS

a. This power tool is intended to function as a grinder, sander, wire

brush, polisher, carving 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. 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.

c. The rated speed of the grinding accessories must be at least

equal to the maximum speed marked on the power tool. Grinding

accessories running faster than their rated speed can break and fly

apart.

d. 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 controlled.

e. The arbour size of wheels, sanding drums or any other accessory

must properly fit the spindle or collet of the power tool. Accessories

that do not match the mounting hardware of the power tool will run out of

balance, vibrate excessively and may cause loss of control.

f. Mandrel mounted wheels, sanding drums, cutters or other

accessories must be fully inserted into the collet or chuck. If the

mandrel is insufficiently held and/or the overhang of the wheel is too

long, the mounted wheel may become loose and be ejected at high

velocity.

g. Do not use a damaged accessory. Before each use inspect the

accessory such as abrasive wheels for chips and cracks, sanding

drum 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 could

give the operator an electric shock.

k. Always hold the tool firmly in your hand(s) during the start-up.

The reaction torque of the motor, as it accelerates to full speed, can

cause the tool to twist.

l. Use clamps to support workpiece whenever practical. Never hold

a small workpiece in one hand and the tool in the other hand while

in use. Clamping a small workpiece allows you to use your hand(s) to

control the tool. Round material such as dowel rods, pipes or tubing have

a tendency to roll while being cut, and may cause the bit to bind or jump

toward you.

m. 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.

n. 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.

o. After changing the bits or making any adjustments, make sure

the collet nut, chuck or any other adjustment devices are securely

tightened. Loose adjustment devices can unexpectedly shift, causing

loss of control, loose rotating components will be violently thrown.

p. 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.

q. 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.

r. Do not operate the power tool near flammable materials. Sparks

could ignite these materials.

s. Do not use accessories that require liquid coolants. Using water

or other liquid coolants may result in electrocution or shock.

t. Use completely unrolled and safe extension cords with a capacity

of 5 Amps at least.

KICKBACK AND RELATED WARNINGS

Kickback is a sudden reaction to a pinched or snagged rotating wheel,

sanding band, 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. 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. The operator can control

kickback forces, if proper precautions are taken.

b. 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.

c. Do not attach a toothed saw blade. Such blades create frequent

kickback and loss of control.

d. Always feed the bit into the material in the same direction as

the cutting edge is exiting from the material (which is the same

direction as the chips are thrown). Feeding the tool in the wrong
