INSTALLATION
Requirements to the air supply
The pneumatic drill works optimally at an operating pressure of 6 bar, measured at the air inlet.
The distance from the air supply to the pneumatic drill should not be longer than 5 m. We recommend installing an
oiler or a maintenance unit upstream the machine for compressed air preparation.
Use acid and resin-free lubricating oil, like SAE 5W - SAE 10W, for proper functioning of the pneumatic drill.
Attention! Do not use viscous oil.
Use an antifreeze lubricant, e.g.:
• “BP-Energol AX 10”,
• “Kilfrost” ,
• or “Kompranol N74” in winter and if the compressed air is very moist.
The supplied compressed air has to be free of:
• Foreign particles,
• humidity.
Pay attention that all hoses:
• Have a cross section being large enough,
• do not have any restrictions or buckles,
• are designed for a minimum operating pressure of 6 bar,
• are replaced regularly at preventative maintenance,
• have an oil resistant inner surface and an abrasion-resistant outer surface,
• are proved and specied to be non-conductive when being used next to electric conductors.
Always use hoses, lubricating oil and antifreeze lubricants, which meet the local safety requirements for use in areas
exposed to explosion hazards.
Connecting the air supply to the pneumatic drill
Remove the locking cap from the air connection 3. Connect the pneumatic hose (not contained in the scope of
delivery). For underwater use, additionally connect an exhaust hose (not contained in the scope of delivery) to the
threaded nozzle 4. Optionally, you can screw in a sound absorber instead of a threaded nozzle.

STARTUP
Mounting the drill bit
Ensure the machine is not connected to the air supply, when mounting the drill bit.
Open the drill chuck 6 by turning, until the drill bit can be mounted. Insert the drill bit. Put the drill chuck key 7 (see
g.3) into the corresponding holes of the drill chuck 6 and tighten the drill bit evenly.

Fig.3 Fig.4
When connecting the machine, ensure that the valve trigger 1 (see g. 4) is not actuated. Before connecting, blow
out the pneumatic hose. Never connect a pressurized pneumatic hose (see safety instructions for prevention of hazards
caused by compressed air). First connect the machine and then the air supply.
Replacing the drill bit
Disconnect the pneumatic hose. Wear protective gloves when replacing the drill bit.
The drill bit and the drill chuck can heat up during longer operation. Open the drill chuck 6 by turning it until the
drill bit can be taken out.
Prior to starting work
Check:
• The oil level, if necessary, rell oiler (line oiler or maintenance unit)
• if the drill bit is rmly clamped to the drill chuck,
• if the pneumatic hose is correctly connected.
Start the machine by actuating the valve trigger 1 and start operation. (The speed can be adjusted by opening the
valve more or less, or by increasing, respectively lowering, the drill pressure.)
After nishing the work
• Shut the valve.
• Shut compressed air supply and disconnect air hose.
• Dismount drill bit, if necessary.
UNDERWATER USE
Before underwater operation
Ensure that:
• The exhaust hose is connected and xed at the supply hose,
• the exhaust hose is long enough to protrude above the water. In case of a short exhaust hose (in the water) a
reverse valve is used, so that water cannot get into the machine when plunging with the machine,
• the machine is tested for leakage and for the functioning of all parts (drilling, blowing, valves, etc.).
Notice: Keep in mind that 10 meter water depth corresponds to 1 bar.
When working in greater depths match the diameter of the supply and exhaust hose appropriately.
After underwater operation
• Clean and dry the machine with compressed air.
• Spray all moving parts with multi-oil-spray.

· Markings on the machine.
· Avoid the generation of sparks.
·When operating the machine, do not push or beat against other material and hold the machine rmly
and safely by hand.
·Do not slide the machine over the ground.
·If heat generation exceeds the specied surface temperature, the machine has to be stopped instantly. It
only may be re-started after having eliminated the cause for the fault.
·The work area and the next working areas should always be protected from sparks.
·Flammable and explosible material has to be removed from the work area before work is started.
Among others, this relates to dust deposits, cardboard, packing material, textile, wood and wooden splints,
but also ammable uids and gas.
Ensure adequate lighting.
Be extra careful in unfamiliar surroundings. There is a risk of hidden hazards such as electric lines or other
supply lines. Make sure when operating the machine that no electrical cables, gas pipes or similar could be
damaged. Use suitable and personal protective equipment.
SAFETY INSTRUCTIONS FOR PREVENTION OF HAZARDS CAUSED BY COMPRESSED AIR
WARNING – Compressed air can cause severe injury. Before working on the tools (e.g. installation,
changing accessories or machine tools, prior to a long standstill, maintenance, etc.) depressurize
pneumatic equipment (close valve and depressurize pneumatic hose).
CAUTION – Risk of injury by whipping pneumatic hose.
Check pneumatic hoses, connection components and ttings regularly for any damages and proper xture.
When connecting / disconnecting the machine to / from the pneumatic supply, please pay careful attention not to
actuate the start lever while doing so. Never remove a pressurized pneumatic hose. Always switch the power supply off
rst and then depressurize the machine by pressing the valve latch.
The maximum operating pressure (ow pressure) according to the technical specication must not be exceeded.
A pressure regulator has to be installed, which regulates the pressure before it reaches the machine. Never direct a
10
pneumatic hose at yourself or anyone else. Never clean your clothes with compressed air. Direct cold air away from
your hands. Do not pull or carry the machine by the pneumatic hose. When using claw couplings make sure that they
are tted with a suitable lock mechanism (e. g. lock pin) and a safety chain.
SAFETY INSTRUCTIONS FOR PREVENTION OF OPERATING HAZARDS
Before starting work make sure that the hands are protected against: impacts, crushing, hits, cuts, abrasions and heat.
The operating and maintenance personnel must be physically able to handle the bulk, the weight, the power and/or
the torque of the machine. Do not use the machine if you have taken any medication or drugs, after drinking alcohol
or with any other constraints on your vision, reaction time or judgment. Work in the best possible position so that you
can react with both hands to any normal or unexpected movements of the machine. Maintain a balanced body position
and secure footing in order to avoid improper strain and to be able to support the reaction torque of the machine. If you
cannot safely support the reaction torque of the machine, use a torque reaction bar (e.g. linear stand, telescopic arm,
holding xture/ holder-on, support grip).
Additionally observe the following:
• Operate the machine only after having carefully read the operation manual.
• Use drill bits appropriate for the application with this machine.
• The work place has to be secured according to the instructions, in order to avoid injury to persons nearby due to
projectiles coming-off.
• The machine is for hand-held operation only.
• Consider the producer’s specication when selecting the drill bit.
• Check the secure xing of drill chuck and drill bit before starting work.
• Remove the drill chuck key 7 (if available) before starting the machine (see g. 3).
• If the machine blocks, higher reaction torques can occur. Blocking can be caused by: overload, tilting of the drill
bit in the work piece or when penetrating the material to be drilled. Do not let the drill bit rumble on the work piece, as
this will most likely increase the vibration. When drilling through-holes, reduce the contact pressure shortly before the
drill bit penetrates the material (for thin walled work pieces there is the risk that the drill hitches the work piece and lifts
it.)
• It is possible that the drill bit keeps on running after the machine has been switched off. Wait until it stops and
deposit the hand-held machine in a secure position.
• Never stop the drill chuck or the drill bit by hand.
SAFETY INSTRUCTIONS FOR PREVENTION OF ENTANGLEMENT HAZARDS
CAUTION – Loose clothing, personal jewellery (e.g. necklace), scarves/ ties, long hair or gloves can get
caught up in the machine tool or accessories and thus cause severe injuries (lack of breath by throttling,
abrasions, skin injuries and/ or cuts and lacerations)
Wear suitable, close tting work clothing!
Wear a hair net, if you have long hair.
When handling the machine, jewellery, necklaces, etc. have to be removed or are forbidden, respectively.
SAFETY INSTRUCTIONS FOR PREVENTION OF NOISE HAZARDS
Always wear hearing protection (EN 352) – This refers to the operator, as well as to any other person
within the vicinity of the machine. Observe the instructions of the employer and of the professional
association.
High noise levels during operation can cause permanent hearing problems such as tinnitus (ringing,
buzzing, whistling or humming in the ears), hardness of hearing or even deafness.
· Before starting work, ensure that the provided, respectively the factory-made, sound absorbers are mounted and in
proper condition.
· If possible, use sound absorbing material, in order to avoid ringing noise at the work pieces.
