When connecting / disconnecting the machine to / from the pneumatic supply, please pay attention not to
actuate the valve while doing so. Never remove a pressurized pneumatic hose. Always switch the power
supply off first and then depressurize the machine.
The maximum operating pressure (flow pressure) according to the technical specification must not be exceeded.
A pressure regulator has to be installed, which regulates the pressure before it reaches the machine. Never direct a
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 fitted 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 fixture/ 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 specification when selecting the drill bit.
•
Check the secure fixing of drill chuck and drill bit before starting work.
•
Remove the drill chuck key 7 (if available) before starting the machine (see fig. 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 fitting 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.
