Safety Instructions for Prevention of Hazards caused by Hydraulic
WARNING – Hydraulic 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 hydraulic equipment.
CAUTION – Risk of injury by whipping hydraulic hose.
Check hydraulic hoses, connection components and fittings regularly for any damages and
proper fixture.
When connecting / disconnecting the machine to / from the hydraulic supply, please pay careful attention
not to actuate the valve while doing so. Never remove a pressurized hydraulic hose. Always switch the
power supply off first and then depressurize the machine.
The maximum operating pressure according to the technical specification must not be exceeded.
A pressure regulator should be installed, which regulates the pressure before it reaches the machine.
Never direct a hydraulic hose at yourself or anyone else. Do not carry or pull the machine at the hydraulic
hose.
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 consider the following:
Operate the machine only after having carefully read the operation manual.
Use appropriate drill bits.
The work place has to be secured according to the instructions, in order to avoid injury due to flying
particles.
The machine is for hand-held operation only.
Consider the producer’s specification when selecting the drill bit.
Check the secure fixing of the drill chuck and the drill bit before starting work.
If the machine blocks, then 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. Do not let the drill bit rumble on
the work piece, as this increases the vibration. When drilling through-holes, reduce the contact pressure
shortly before the drill bit penetrates the material (for thin work pieces there is the risk that the drill
hitches and lifts the work piece.)
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.
