WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised test given
in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool. However if the tool is used for diff erent
applications, with diff erent accessories or poorly maintained, the vibration emission may diff er. This may signifi cantly increase
the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may signifi cantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the eff ects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work patterns.
WARNING Read all safety warnings, instructions,
illustrations and specifi cations provided with this power
tool. Failure to follow all instructions listed below may result
in electric shock, fi re and/or serious injury.
Save all warnings and instructions for future reference.

g) Mandrel mounted wheels, sanding drums, cutters or
other accessories must be fully inserted into the collet
or chuck. The "overhang" or the length of the mandrel
from the wheel to the collet must be minimal. If the
mandrel is insuffi ciently held and/or the overhang of the
wheel is too long, the mounted wheel may become loose
and ejected at high velocity.
h) 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 noload
speed for one minute. Damaged accessories 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 fl ying debris
generated by various operations. The dust mask or
respirator must be capable of fi ltrating 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 accessory may fl y 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) Always hold the tool fi rmly in your hands during the
start-up. The reaction torque of the motor, as it accelerates
to full speed, can cause the tool to twist.
m) 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 both hands 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.
n) 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.
o) 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.
p) 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.
q) 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.
r) 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.
s) Do not operate the power tool near fl ammable
materials. Sparks could ignite these materials.
t) 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 fi 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 reactions
or 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 saw chain woodcarving blade or
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 direction causes the cutting
edge of the bit to climb out of the work and pull the tool in
the direction of this feed.
e) When using steel saws, cut-off wheels, high-speed
cutters or tungsten carbide cutters, always have the
work securely clamped. These wheels will grab if they
become slightly canted in the groove, and can kickback.
When a cut-off wheel grabs, the wheel itself usually breaks.
When the steel saw, high-speed cutters or tungsten carbide
cutter grab, it may jump from the groove and you could lose
control of the tool.
Safety Warnings Specifi c for Grinding
a) Use only wheel types that are recommended for your
power tool and only for recommended applications. For
example: do not grind with the side of a cut-off wheel.
Abrasive cut-off wheels are intended for peripheral grinding,
side forces applied to these wheels may cause them to
shatter.
a) For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved
shoulder fl ange that are of correct size and length.
Proper mandrels will reduce the possibility of breakage.
b) d) Do not position your hand in line with and behind
the rotating wheel. When the wheel, at the point of
operation, is moving away from your hand, the possible
kickback may propel the spinning wheel and the power tool
directly at you.
c) 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.
d) 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.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Always wear goggles when using the machine. It is
recommended to wear gloves, sturdy non slipping shoes
and apron.
Always disconnect the plug from the socket before carrying
out any work on the machine.
Only plug-in when machine is switched off .
Keep mains lead clear from working range of the machine.
Always lead the cable away behind you.
After switching off , the machine will not be idle immediately.
(After-running of the work spindle.) Allow the machine to
come to a stop before putting down.
Never reach into the danger area of the machine when it is
running.
Only use tools whose permitted speed is at least as high as
the highest no-load speed of the machine.
Check grinding tools before use. The grinding tool must be
properly mounted and turn freely. Perform a test run for at
least 30 seconds without load. Do not use damaged, out of
round or vibrating grinding tools.
When grinding metal, fl ying sparks are produced. Take care
that no persons are endangered. Because of the danger of
fi re, no combustible materials should be located in the
vicinity (spark fl ight zone). Do not use dust extraction.
Due care should be taken that no sparks or sanding dust
fl ying from the workpiece come into contact with you.
The adjusting nut must be tightened before starting to work
with the machine.
Under the eff ect of extreme electromagnetic interferences
from the outside, temporary variations in the speed of
rotation could arise in particular cases.
Always use and store the grinding disks according to the
manufacturer's instructions.
