Operating Instructions
B.4.6 Danger arising from power failure
Constructive measures prevent an uncontrolled restarting
of the system after loss of power.
B.4.7 Endangering the environment with engine oil
There is engine oil in the system. When oil is changed,
any resulting used oil must be consigned to a used-oil
collection point or to a waste disposal company. The
same applies to oil or oil-water mixtures which are
trapped if leaks occur.
B.4.8 Endangering the environment with waste
water
Local regulations should be observed for the disposal of
waste water.
B.5 Maintenance and monitoring
The relevant instructions must be complied with in order
to ensure the safe operation of the system and to prevent
dangers from occurring during maintenance, monitoring
and inspection.
B.5.1 Maintenance
Maintenance work must be carried out by a competent
person at regular periods according to the specifications
of the manufacturer. When doing so, any prevailing
conditions and safety requirements should be observed.
Work undertaken on the electrical system may be
undertaken only by a trained electrician.
!
Danger!
The system must be switched off and secured against
being switched on again inadvertently or without
authorisation before maintenance and servicing
operations are carried out.
Compressed air tanks and lines remain under pressure
even after the system has been switched off. Before
doing work on the system, it is essential that pressure is
reduced by opening the pressure relief valve. Then check
absence of pressure at:
n pressure gauge at pressure tanks
n pressure gauge at pressure switch and
n pressure gauge at the maintenance unit
Risk of injury from unexpected exit of jet of water under
high pressure. The high-pressure system remains under
pressure even when the system has been switched off.
Before doing work on the system, it is essential that the
high-pressure system is made pressureless.
