Environmental issues
NOTE
Danger to the environment due to improper handling!
Environmentally conscious and anticipatory behavior of staff avoids environmentally hazardous im-
pacts.
The following principles apply for environmentally conscious behavior:
Environmentally hazardous substances must not get into the soil or into the drains. They
should be kept in appropriate containers.
Environmentally hazardous substances must be brought to utilization or disposal according to
regional regulations.
When dealing with working fluids always keep aware of the safety data sheet of the corre-
sponding manufacturer.
Personnel
Unless otherwise noted, all maintenance tasks described in this chapter can be performed by the
operator of the unit.
Other maintenance tasks have to be performed by specially trained qualified personnel. This is
specially noted in the description of the single maintenance task.
Personal protective gear
The following personal protective gear for all maintenance work has to be worn:
Protective footwear
Protective gloves
Protective eyewear
9.2. Maintenance schedule
The maintenance tasks necessary to ensure proper operation of the unit are described in the
maintenance schedule.
The maintenance intervals are as follows:
regularly
every 3 months
every 6 months
If increased wear of single components or component groups has been determined during regular
inspections, the operator of the unit has to reduce the required maintenance intervals on the basis
of the actual signs of wear. Deviations from normal operation of the unit lead to the assumption that
the functions are impaired. These then have to be subjected to an inspection by specialized staff.
