Hydraulic Oil Reservoir
Return Filter
The filter should be changed every 1000 hours, however there is an integral filter indicator on the side
of the filter head and, should this indicate on the JVM whilst the suction fan is operating, then the filter
is contaminated and requires changing at an earlier interval.
Renewing the Return Filter
Unscrew cover (A) and lift out the cartridge element (B). Fit new cartridge and screw on the cover
Renewing the Suction Filters
Note: Drain Oil Before Removing Suction Filters.
The oil can be drained by removing the drain plug (C) located under the systems locker or by using a
propriety vacuum pump or oil extractor/syringe.
The filters (D) should be changed whilst the system is empty.
System Refilling
The system capacity dry is 61 litres.
Raise the body and engage the body prop (E) in its highest
position. The level (F) should be 10mm above the lower red line
(G) on the gauge.
It is important that the correct level is maintained as under filling
can adversely affect the heat dissipation rate of the oil, whilst over
filling can cause oil to overflow when the body is lowered.
