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 ammable 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.

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 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 rm 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

reaction 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.

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 of 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 Specic for Grinding and Abrasive Cutting-O

Operations:

a) Use only wheel types that are recommended for your power tool

and the specic guard designed for the selected wheel. Wheels

for which the power tool was not designed cannot be adequately

guarded and are unsafe.

b) The grinding surface of centre depressed wheels must be

mounted below the plane of the guard lip. An improperly mounted

wheel that projects through the plane of the guard lip cannot be

adequately protected.

c) 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.

d) Wheels must be used only for recommended applications. For

example: do not grind with the side of cut-o wheel. Abrasive cut-

o wheels are intended for peripheral grinding, side forces applied to

these wheels may cause them to shatter.

e) Always use undamaged wheel anges that are of correct size and

shape for your selected wheel. Proper wheel anges support the

wheel thus reducing the possibility of wheel breakage. Flanges for

cut-o wheels may be dierent from grinding wheel anges.

f) 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 Specic for Abrasive Cutting-O

Operations:

a) Do not “jam” the cut-o 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 possible 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 o the power tool and hold the power tool motionless

until the wheel comes to a complete stop. Never attempt to

remove the cut-o 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 workpiece. Let the

wheel reach full speed and carefully re-enter the cut. The wheel

may bind, walk up or kickback if the power tool is restarted in the

workpiece.

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. Support must be placed under the

workpiece near the line of cut and near the edge of the workpiece on

both sides of the wheel.

f) Use extra caution when making a “pocket cut” into existing walls

or other blind areas. The protruding wheel may cut gas or water

pipes, electrical wiring or objects that can cause kickback.

Safety Warnings Specic for Sanding Operations:

a) Do not use excessively oversized sanding disc paper. Follow

manufacturers recommendations, when selecting sanding paper.

Larger sanding paper extending beyond the sanding pad presents

a laceration hazard and may cause snagging, tearing of the disk or

kickback.

Safety Warnings Specic for Polishing Operations:

a) Do not allow any loose portion of the polishing bonnet or its

attachment strings to spin freely. Tuck away or trim any loose

attachment strings. Loose and spinning attachment strings can

entangle your ngers or snag on the workpiece.

Safety Warnings Specic for Wire Brushing Operations:

a) Be aware that wire bristles are thrown by the brush even during

ordinary operation. Do not overstress the wires by applying

excessive load to the brush. The wire bristles can easily penetrate

light clothing and/or skin.

b) If the use of a guard is recommended for wire brushing, do not

allow any interference of the wire wheel or brush with the guard.

Wire wheel or brush may expand in diameter due to work load and

centrifugal forces.

Additional safety Warnings:

a) In tools adapted to attach grinding wheels with a threaded hole,

check whether the thread length of the grinding wheel is suitable for

the length of the spindle thread.

b) Secure the workpiece. Attaching the workpiece to the clamping

device or vise is safer than holding it in your hand.

c) Do not touch the cutting and grinding discs until they have cooled

down.

d) When using a quick-setting ange, make sure that the internal

ange mounted on the spindle is equipped with a rubber O-ring

and that the ring is undamaged. It should also be ensured that

the surfaces of the external ange and the internal ange are

clean.

e) Use the quick clamping ange only with abrasive and cutting

discs. Only use undamaged and properly functioning anges.

f) In the event of a temporary power outage in the network or after

removing the plug from the power socket with the switch in the

"on" position, before re-starting, unlock the switch and set it in the

o position.

CAUTION! This device is designed to operate indoors. The design

is assumed to be safe, protection measures and additional safety

systems are used, nevertheless there is always a small risk of injuries

at work.
