f) Threaded mounting of accessories must match the grinder
spindle thread. For accessories mounted by flanges, the
arbour hole of the accessory must fit the locating diameter of
the flange. 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.
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 appli-
cation, 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 work-
piece 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 the power tool by insulated gripping surfaces only,
when performing an operation where the cutting accessory
may contact hidden 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.
k) 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.
l) Do not run the power tool while carrying it at your side. Acci-
dental contact with the spinning accessory could snag your clothing,
pulling the accessory into your body.
m) 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.
n) Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
o) 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 direc-
tion 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 opera-
ting 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. Acces-
sory may kickback over your hand.
22
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 or 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 Specific for Grinding and Abrasive Cutting-
Off Operations:
a) Use only wheel types that are recommended for your power
tool and the specific 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 the 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-off wheel. Abra-
sive 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
size and shape for your selected wheel. Proper wheel flanges
support the wheel thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from grinding wheel
flanges.
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 Specific for Abrasive Cutting-Off
Operations:
a) Do not "jam" the cut-off wheel or apply excessive pressure.
Do not attempt to make an excessive depth of cut. Overstres-
sing 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 rota-
ting 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 off the power tool and hold the power tool
motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-off 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. Supports 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 Specific for Sanding Operations:
a) Do not use excessively oversized sanding disc paper.
Follow manufacturers recommendations, when selecting san-
ding paper. Larger sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause snagging, tearing
of the disc or kickback.
Safety Warnings Specific 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 AND WORKING INSTRUCTIONS
Always check if the spindle lock button is fully released before
switching on the tool! After using the spindle lock to tighten / loosen
the abrasive disc, it is possible that the button may stick in the lock
position.
When grinding metal, flying sparks are produced. Take care that
no persons are endangered. Because of the danger of fire, no
combustible materials should be located in the vicinity (spark flight
zone). Do not use dust extraction.
Avoid flying sparks and sanding dust hit your body.
Never reach into the danger area of the machine when it is running.
Chips and splinters must not be removed while the machine is
running.
Immediately switch off the machine in case of considerable
vibrations or if other malfunctions occur. Check the machine in order
