8.4.2 System pressure
Maximum system pressure must be checked daily. After starting the pump, the pres-
sure can be read on the pressure gauge on valve block. The pressure must corre-
spond with pressure indicated on the hydraulic diagram. Changing of the pressure is
done by adjusting the pressure limiting valve (see chapter „Spare part drawings and
part lists/design hydraulic aggregate“).
8.4.3 Oil tank
Check the oil level daily. If level drops below lower limit oil must be added.
Prior to adding or changing oil, lower all cylinders and empty the oilside of the accu-
mulator (lever of ball valve in position „accumulator empty“. Following this procedure,
the oil pressure p3 must be set again (see 8.3.1.1).
When adding oil, the same make and type of oil must be used. If the oil make or type
must be changed, the system must be completely emptied and flushed with the new
type of oil prior to filling the system with the new oil. This will avoid potential problems
with sticky valves.
Oil used at the factory: SHELL Tellus 46.
Used hydraulic oil must be disposed of in suitable manner; please ensure that oil
does not find its way into the sewer.
8.4.4 Filter
The filter element must be checked regularly. Initial check one week after start-up
and thereafter every three months. To check this, the red plastic cover of the filter is
removed giving access to the filter element. If it is dirty and clogged it must be re-
placed by a new one.
