2. Operational safety
2.1 General
In order to maintain the operational safety of the
hydraulic hammer, repair work should only be
carried out by trained specialists using genuine
Krupp spare parts. This work should therefore only
be entrusted to Krupp trained specialists who know
which spare parts need replacing and when.
2.2 Accident prevention
regulations
To avoid the possibility of injury, please
observe the following instructions
Before starting work:
Please familiarise yourself with the repair manual
and the appropriate regulations before starting
work on the hydraulic hammer.
When using or working on hydraulic hammers in
the countries of the European Union, the
regulations of the EC machinery directive
98/37/EG must be observed and followed, as must
national accident prevention regulations and
regulations covering pressurised vessels.
In countries outside the European Union, the valid
local statutes and regulations will apply.
The hydraulic hammer should only be repaired by
specialists.
When lifting/transporting the hydraulic hammer,
use only the lug provided and hoisting equipment
with sufficient capacity.
Clear hand signals must be agreed on with the
hoist operator beforehand.
Never stand beneath hoisted loads.
Stand the hydraulic hammer in a suitable device
and secure it against falling over.
The repair area must be clear and easily
accessible.
Always wear protective glasses when fitting or
removing the working tool since metal splinters
may fly off when hammering out the locking pins.
Working tools should only be fitted as described in
the operating manual.
The hammer's integrated piston accumulator is
pressurised.
Before dismantling the hydraulic hammer and
before removing the complete filling valve “G”,
the piston accumulator must be fully
depressurised.
Never use nails, screwdrivers or similar objects to
bleed off the gas since this would damage the
filling valve. Bleed off the gas using only the
nozzle of the filling/test hose.
Never use your fingers to check the alignment of
the working tool recesses to the oblong holes for
the locking bars.
Never dismantle a hydraulic hammer which is still
hot from running as there is a high risk of injury
through burns. Always wait until the hammer has
cooled down before dismantling it. Collect any oil
which runs out and dispose of it correctly.
The piston accumulator must only be filled with
nitrogen from the green cylinder.
Make sure that no other gas (e.g. air or oxygen) is
allowed into the piston accumulator.
When attaching the adapter use only Allen screws
with a material quality of σs= 640 N/mm2(material
quality 8.8)!
