1. Safety
1.1 General safety instructions
Do not use this Air Die Grinder before you have thoroughly read and completely
understood this manual, specifically the “General safety instructions” and ‘’Specific safety
information”, including the figures, specifications, safety regulations and the signs
indicating DANGER, WARNING and CAUTION.
WARNING: When using the Air Die Grinder, basic safety precautions should
always be followed to reduce the risk of electrical shock, fire and personal injury.
Please also observe the relevant national industrial safety regulations. Non-observance of
the safety instructions can lead to an electric shock, burns and/or severe injuries.
This manual should be kept for later use and enclosed with the Air Die Grinder, should it
be passed on or sold.
Work area
1. Keep your work area clean and well lit. Cluttered and dark work areas increase the
chance of accidents;
2. Do not operate Air Die Grinder in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Sparks could come off the workpiece which
could ignite the dust or fumes.
3. Keep bystanders, children and visitors away while operating an Air Die Grinder.
Distractions can cause you to lose control.

Personal safety
1. Stay alert, watch what you are doing and use common sense when using the Air
Die Grinder. Do not use it while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating the Air Die Grinder may
result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught
in moving parts.
3. Avoid accidental starting. Be sure that the on-/off- trigger is not pressed when
plugging in the Air Die Grinder to the air supply. Carrying or plugging in the Air Die
Grinder with your hands on the trigger increases the chance of accidents.
4. Never place hands, fingers, gloves or clothing near rotating tool parts.
5. Remove adjusting keys or wrench before starting the Air Die Grinder. A wrench or
a key that is left attached to a rotating part of the Air Die Grinder may result in
personal injury.
6. Do not overreach. Keep proper footing and balance at all times. This enables better
control of the Air Die Grinder in unexpected situations.
7. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety
shoes, hard hat and hearing protection must be used for optimal safety.
8. If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection can
reduce dust-related hazards.
WARNING: Wear ear and eye protection when using this power tool.

Air Die Grinder use and care
1. Do not force the Air Die Grinder. Use the correct tool for your application. The
correct tool will do the job better and safer at the rate for which it is designed.
2. Do not use the Air Die Grinder when the trigger does not turn it on or off. Any tool
that cannot be controlled is dangerous and must be repaired.
3. Disconnect the air supply before making any adjustments, changing accessories, or
storing the Air Die Grinder. Such preventive safety measures reduce the risk of
starting the tool accidentally.
4. Store your Air Die Grinder out of reach for children and other untrained persons.
Air Die Grinders are dangerous in the hands of untrained users.
5. Maintain the Air Die Grinder with care. Check for misalignment of moving parts,
breakage of parts and any other condition that may affect the Air Die Grinder’s
operation. If you detect damage, have the Air Die Grinder serviced before use.
Many accidents are caused by poorly maintained tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
7. Only use accessories that are recommended by EUROBOOR for your Air Die
Grinder. Accessories that are suitable for one tool may become hazardous when
used on another tool.
8. Use the Air Die Grinder, accessories and tool bits etc. in accordance with these
instructions and in the manner intended for the particular type of tool, taking into
account the working conditions and the work to be performed. Use of the tool for
operations different from intended could result in a hazardous situation.

Service
1. Service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in risk of injury.
2. When servicing a tool, use only identical replacement parts. Follow instructions in
the maintenance section of this manual. Use of unauthorised parts or failure to
follow maintenance instructions may create a risk of injury.
WARNING: Remove the air supply from the machine before carrying out any
installation, adjustment, servicing or maintenance.
Residual risk
In spite of following the relevant safety regulations and their implementation, every tool
involves a certain residual risk which cannot be completely excluded by safety
mechanisms. Power tools must therefore always be operated with caution!

1.3 Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged grinding accessory. Pinching or snagging
causes rapid stalling of the grinding accessory which in turn causes the uncontrolled grinding
tool to be forced in the direction opposite of the accessory’s rotation at the point of the
binding.
For example, if a rotary burr is snagged or pinched by the workpiece, the edge of it that is
entering into the pinch point can dig into the surface of the material causing the rotary burr
to climb out or kick out .The rotary burr may either jump toward or away from the operator,
depending on direction of its movement at the point of pinching.
Kickback is the result of grinding tool misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below:
1. Maintain a firm grip on the grinding tool and position your body and arm to allow you
to resist kickback forces.
2. Always operate the machine using two hands, 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.
3. When using rotary burrs or other grinding accessories, always have the workpiece
securely clamped. These grinding accessories will grab if they become slightly canted
in the groove, and can kickback. When a rotary burr grabs, it may jump from the groove
and you could lose control of the grinder.
4. Never place your hand near the grinding accessory. Accessory may kickback over your
hand.

www.euroboor.com
13
5. 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 accessory’s movement at the
point of snagging.
6. Use special care when working corners, sharp edges etc. Avoid bouncing and snagging
the grinding accessory. Corners, sharp edges or bouncing have a tendency to snag the
grinding accessory and cause loss of control or kickback.
7. Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create
frequent kickback and loss of control.

2.6 Environmental
Separate collection. This product must not be disposed of with normal household
waste.
Separate collection of used products and packaging allows materials to be recycled
and used again. Re-use of recycled materials helps prevent environmental
pollution and reduces the demand for raw materials.
Local regulations may provide for separate collection of electrical products from the
household, at municipal waste sites or at the retailer when you purchase a new product.
