4. Special Safety Instructions
4.1 Safety Warnings Common for the use of Rotary Impact Tool Operations:
a) This power tool is intended to function as Rotary Impact Tool. Read all safety
warnings, instructions, illustrations and specifications provided with this power tool.
Failure to follow all instructions listed below may result in electric shock, fire and/or
serious injury.
b) No other operation than Rotary Impact Surface Preparation / Bristle Blasting shall be
performed with this power tool. Operations for which the power tool was not
designed may create a hazard and cause personal injury.
c. Only use MontiPower®Bristle Blaster®Belts and MontiPower®Adaptor Systems with
this tool. 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.
d) Do not use a damaged Bristle Blaster®Belt or Adaptor System, inspect before use.
e) After replacement of the Bristle Blaster®Belt, check Adapter System for correct
assembly.
f) After fitting accessories such as the Adapter System and Bristle Blaster®Belt, always
remove Allen key / Torx wrench. Always ensure the Allen key / Torx wrench is
removed prior to switching on the tool.
g) On setting down the tool on a bench or on the floor, the label must always point
upward.
h) If the tool is not in use, disconnect from the power supply and store in a suitable,
dry place to prevent unintentional or unauthorised use in the absence of an
authorised individual.
i) In use, always hold by the tool body and the vertical handle.
j) Use Bristle Blaster®Belt in the correct operating direction (Figure 3).
k) The Bristle Blaster®Belt can produce sparks on machining hard surfaces.
l) If the tool suddenly feels different (level of vibration) or produces a different noise
(pitch), the tool should be shut down immediately and the accessories such as the
Adapter System, Bristle Blaster®Belt checked for damage.
m) Wear personal protective equipment. Depending on application, 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
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
WARNING - Read all safety warnings and instructions. Failure to follow all safety
warnings and instructions may result in electric shock, fire and/or serious injury.

EN Operating instructions
filtering particles generated by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
n) 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.
o) Hold power tool by insulated gripping surfaces only, when performing an operation
where the Bristle Blaster®Belt may contact hidden wiring or its own cord. The Bristle
Blaster®Belt contacting a "live" wire may make exposed metal parts of the power
tool "live" and could give the operator an electric shock.
p) 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.
q) Do not run the power tool while carrying it at your side. Accidental contact with the
spinning Bristle Blaster®Belt could snag your clothing, pulling the accessory into your
body.
r) Regularly clean the power tool’s air vents (Figure 2). The motor’s fan will draw the
dust inside the housing and excessive accumulation of powdered metal may cause
electrical hazards. The air vent cap may be removed for cleaning, use non-metallic
objects only.
s) Do not operate the power tool near flammable materials. Sparks could ignite these
materials.
t) Do not use any liquid coolants. Using water or other liquid coolants may result in
electrocution or shock.
4.2 Kickback and Related Warnings
Kickback is a sudden reaction to a rotating wheel which can cause rapid stalling of
the rotating Bristle Blaster®Belt which in turn causes the uncontrolled power tool to
be forced in the direction opposite of the Bristle Blaster®Belt’s rotation.
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 Bristle Blaster®Belt. 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 Bristle Blaster®Belt’s
movement at the point of snagging.
d) Use special care when working corners, sharp edges etc. Avoid bouncing and
snagging the Bristle Blaster®Belt. Corners, sharp edges or bouncing have a tendency
to snag the rotating Bristle Blaster®Belt and cause loss of control or kickback,
damage of the Bristle Blaster®Belt and even brake of the tooth belt.
e) Do not attach any other belt or belt Adaptor System than the ones provided by the
manufacturer.

4.3 Additional Safety Instructions
WARNING – Always wear protective goggles.
• Accessories must be stored and handled with care in accordance with the
manufacturer's instructions.
• The workpiece must lay flat and be secured against slipping, e.g. using clamps.
Large workpieces must be sufficiently supported.
• We recommend connecting a residual current circuit-breaker (FI) upstream.
When the tool is shut down via the FI circuit-breaker, it must be checked and
cleaned. See chapter 9. Cleaning for more information on cleaning the motor.
• Damaged, eccentric or vibrating tools must not be used.
• Disconnect the tool from the mains power supply before making any
adjustments, converting or servicing the machine.
• A damaged or cracked handle must be replaced. Never operate a machine
with a defective handle.
• A damaged or cracked hand guard must be replaced. Never operate a machine
with a defective Protective Cap.
Reducing dust exposure:
WARNING -Some dust created by the MontiPower®Bristle Blasting®process may
contain chemicals known to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work.
To reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.
This also applies to dust from other materials such as some timber types (like oak or
beech dust), metals, asbestos. Other known diseases are e.g. allergic reactions, respiratory
diseases. Do not let dust enter the body.
Observe the relevant guidelines and national regulations for your material, staff,
application and place of application (e.g. occupational health and safety regulations,
disposal).
Collect the particles generated at the source, avoid deposits in the surrounding area.
Use suitable accessories for special work. In this way, fewer particles enter the environment
in an uncontrolled manner.
Use a suitable extraction unit.
Reduce dust exposure with the following measures:
• do not direct the escaping particles and the exhaust air stream at yourself or nearby
persons or on dust deposits,
• use an extraction unit and/or air purifiers,
