WARNING!
The declared vibration total values and the declared noise emission values given in this instruction manual have been measured in
accordance with a standardised test and may be used to compare one tool with another. They may be used for a preliminary assessment of
exposure.
The declared vibration and noise emission values represent the main applications of the tool. However, if the tool is used for different
applications, used with different accessories, or poorly maintained, the vibration and noise emission may differ. These conditions may
significantly increase the exposure levels over the total working period.
An estimation of the level of exposure to vibration and noise should take into account the times when the tool is turned offor when it is
running idle. These conditions may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration and noise, such as maintaining the tool and the
accessories, keeping the hands warm (in case of vibration), and organising work patterns.
WARNING! Read all safety warnings, instructions,

ROTARY TOOL SAFETY WARNINGS
SAFETY WARNINGS COMMON FOR GRINDING, SANDING,
WIRE BRUSHING, OR ABRASIVE CUTTING-OFF
OPERATIONS
SAFETY WARNINGS COMMON FOR GRINDING
This power tool is intended to function as a grinder, sander,
wire brush, polisher, carving or cut-offtool.
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.
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.
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.
The arbour size of wheels, sanding drum 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.
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 insufficiently held and/
or the overhang of the wheel is too long, the mounted wheel may
become loose and ejected at high velocity.
Do not use a damaged accessory. Before each use inspect

19
ENGLISH
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.
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 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.
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.
Hold power tool by insulated gripping surfaces, 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.
Always hold the tool firmly 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.
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.
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.
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.
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.
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.
Do not operate the power tool near flammable materials. Sparks
could ignite these materials.
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 product 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.
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.
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.
Do not attach toothed saw blade. Such blades create frequent
kickback and loss of control.
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.
When using rotary files, cut-offwheels, 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-offwheel grabs, the
wheel itself usually breaks. When a rotary file, high-speed cutter or
tungsten carbide cutter grabs, it may jump from the groove and you
could lose control of the tool.
SAFETY WARNINGS SPECIFIC FOR GRINDING AND
ABRASIVE CUTTING-OFF OPERATIONS
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-offwheel. Abrasive cut-offwheels
are intended for peripheral grinding, side forces applied to these
wheels may cause them to shatter.
For threaded abrasive cones and plugs use only undamaged
wheel mandrels with an unrelieved shoulder flange that are of
correct size and length. Proper mandrels will reduce the possibility
of breakage.
Do not “jam” the cut-offwheel 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.
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.
When wheel is binding or when interrupting a cut for any
reason, switch offthe power tool and hold the power tool
motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-offwheel 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.
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.
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.

20 ENGLISH
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
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 disc or kickback.
SAFETY WARNINGS SPECIFIC FOR WIRE BRUSHING
OPERATIONS
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.
Allow brushes to run at operating speed for at least one minute
before using them. During this time no one is to stand in front
or in line with the brush. Loose bristles or wires will be discharged
during the run-in time.
Direct the discharge of the spinning wire brush away from you.
Small particles and tiny wire fragments may be discharged at high
velocity during the use of these brushes and may become imbedded
in your skin.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Use personal protective equipment. Always wear eye protection.
Protective equipment, such as a dust mask, non-skid safety shoes,
hard hat, or hearing protection used for appropriate conditions will
reduce personal injuries.
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 hitting your body.
Use only properly fitting and undamaged open-end spanners.
The insertion tools must run completely concentrical. Do not
continue to use out-of-round insertion tools, instead, replace before
continuing to work.
Never reach into the danger area of the product when it is running.
Chips and splinters must not be removed while the product is
running.
Immediately turn offthe product in case of considerable vibrations
or if other malfunctions occur. Check the product in order to find out
the cause.
Make sure that the insertion tool comes to a complete stop before
laying it down.
Under extreme conditions (e.g. smooth-grinding metals with
the arbour and vulcanized fibre grinding wheel), significant
contamination can build up on the inside of the rotary tool.
Do not let any metal parts enter the ventilation slots (danger of short
circuit).
Always use and store accessories according to the manufacturer’s
instructions.
Do not use the product to work on asbestos-containing products.
Determine the composition of the workpiece before beginning work.
Asbestos should only be removed by a qualified professional.
The insertion tool must be clamped at least 10 mm. The inner shank
dimension L0can be used to calculate the maximum permitted
speed of the insertion tool from the specifications provided by
manufacturer of the insertion tool. It must not be less than the
maximum speed of the product.
The workpiece must be fixed if it is not heavy enough to be steady.
Never move the workpiece towards the rotating insertion tool by
hand.
Remove dust and debris from the collet body and clean the insertion
tool mandrel before inserting it.
Insertion tools should be protected from:
• wetness and extreme humidity
• any type of solvent
• extreme changes in temperature
• dropping and bumping
Insertion tools should be stored:
• in an organized way so the insertion tools can be removed without
disturbing or damaging other insertion tools
• with their safety information
Insertion tools should not be dropped, rolled, or bumped.
Turn offthe product immediately if the insertion tool stalls. Do
not turn on the product again while the insertion tool is stalled, as
doing so could trigger a sudden recoil with a high reactive force.
Determine why the insertion tool stalled and rectify this, paying heed
to the safety instructions.
The possible causes may be:
• The insertion tool is tilted in the workpiece to be machined.
• The insertion tool has pierced through the material to be
machined.
• The product is overloaded.
