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 first and then depressurize the machine by
pressing the valve latch.
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 beginning work make sure that the hands are protected from the following hazards whilst
working with the machine: impacts, crushing, hits, cuts, abrasions and heat.
The operating and maintenance personnel must be physically able to handle the bulk, weight,
power and/or 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, then use a torque support (e.g. linear
stand, telescopic arm, holding fixture/ holder-on, support grip). Additionally observe the following:
• Only operate the machine after having carefully read the operation manual.
• Only use impact wrench in combination with appropriate power socket wrenches. Never
use other types of socket wrenches.
• Never use power socket wrenches with worn out drive square. Prior to each application,
check that the drive square at the power socket wrench and the extension or at the spindle of the
impact wrench is not worn out, or if there are any crazes. Ensure that the power socket wrench is
properly seated on the drive square before each startup.
• Prior to each application check that the power adjustment is correctly set. Wrong adjustment
can lead to breaking or tearing of the screw connection, as well as to uncontrolled movements of
the machine.
• Before each startup ensure that the reverse valve for rotation direction left and right is in the
correct position. Do not start the machine, unless the power socket wrench is seated solidly and
correctly on the screw head or on the nut.
• Do not try to hold or guide the machine at the turning power socket wrench.
• Consider enough space behind you when loosening screw connections, so that the
operating hand cannot be jammed.
• Only use extensions, adapters and joints, which are explicitly approved for the application
with impact wrenches.
• If the machine shows any signs of abnormal operation and performance, work must to be
stopped instantly for maintenance and repair.
