10.2.4 Clean the gear unit

To prevent the build­up of dust on the gear unit, cleaning must be done in accordance
with the local operating conditions.
• Remove any dirt adhering to the gear unit, using a hard brush.
• Remove any corrosion.
The gear unit must not be cleaned with high­pressure cleaning equipment.

10.2.5 Check hose lines

Even when adequately stored and subjected to permissible loads, hoses and hose lines are subject to
a natural ageing process. This limits their period of use.
The period of use of the hose lines must not exceed 6 years from the manufacturing
date stamped on them.
The period of use can be determined using available test and empirical values, taking into account the
conditions of use.
The operator of the system must ensure that hose lines are replaced at suitable intervals of
time, even if no defects which may affect their safe operation are identifiable on them.
Hose lines must be inspected for safe working condition by an expert before the plant is first
put into operation and thereafter at least once a year.
If during inspections faults are found, these must be rectified immediately or suitable
countermeasures taken.

10.2.6 Check tightness of screw connections

• The instructions in item 10.1 must be observed!
• Close the stop valves in the coolant in­ and outflow pipes (gear units with cooling coil or water oil­cooling
system).
• Check tightness of all fastening bolts (see item 6.12).
Damaged bolts must be replaced with new bolts of the same type and strength class.
10.3

Final work

For operating and servicing the components, the pertinent instructions manuals and the
specifications in sections 5, "Technical description", and 7, "Start­up", must be observed.
