Power Pack

Fully integrated pump, tank, preset relief valve and return filter. The biggest cause of

hydraulic problems is down to contaminated oil. Change oil and filter at least every 6

months, even though the hydraulic system is a closed system. The only access for

external dirt is through the filter breather. You will have contamination due to seal kit wear

(black sludge in the bottom of the tank, mechanical wear from the gear pump, valve block

and cartridges in addition to water contamination due to tank condensation. See power

pack section for more details.

SOL1 (Hydraulic Outriggers Only)

This valve diverts oil from the outrigger control valve first to the ground control valve and

then to the basket control valve. Never operate the coil unless it is on the valve cartridge.

You risk burning out the coil.

Base Control Valve

This gives you full control over all functions apart from the basket slew. The adjustable

relief valve is set at the factory to approximately 140 bar. It should be set so that when you

lift the bottom boom from rest you can just lift the full safe working load (SWL) plus 10%.

The centre position is closed to prevent oil back feeding and running back to tank when

operating the basket controls.

Slew Motor

The slew motor is bolted directly on the slew platform. Apart from greasing and checking

for oil leaks it requires no maintenance.
