Once the required pressure is achieved, return the directional control valve (7) to the centre position.
This will hold the load. This pressure hold function should not be used as a load holding device. If
load holding is required, a Hi-force inline locking device should be used.
Pull the Directional control valve (7) to the Retract "R" position. The system can now be retracted
using the pump handle (2)
Retract
IMPORTANT:
After operation, fully return all hydraulic fluid to the pump. Monitor the hydraulic fluid level in
the reservoir to prevent over-filling of the tank.
IMPORTANT:
If the hose connections cannot be released by hand, some pressure may be in the retract
hose. Push the directional control valve handle (7) the "A" advance position and operate the
pump handle (2) 1-2 times under no load. Return the directional control valve to the centre
position and commence the disassembly of the system.
NEVER jerk the handle during operation. This makes the pump inefficient and
can cause unexpected over pressurisation. A smooth, steady action, using full
stroke produces the best results and will reduce operator fatigue.
