CONNECT AIR SUPPLY (this causes the piston to bottom, allowing more priming oil into the tool).
All operations should be carried out on a clean bench, with clean hands, in a clean area.
Care MUST be taken, at all times, to ensure that no foreign matter enters the tool, or serious damage may result.
Item numbers in bold refer to the General Assembly of Handle and Parts List on pages 16 and 17, item number 28* refers to the
General Assembly of Cabinet and Parts List on pages 18 and 19.
•
Prior to starting the priming procedure, obtain a suitable container to collect excess oil.
•
Disconnect the air supply and undo the intensifier Oil Reservoir Plug 28*.
•
Top up the reservoir in the cabinet with VG32 Hyspin
If the oil hoses are changed, prime them before connecting, as follows:
•
Disconnect the air supply.
•
Place the oil tank in a higher position than the tool.
•
In that position, unscrew the Bleed Screws 18 and Washers 19 until the oil flows under gravity.
•
Once the oil starts to flow from one of the bleed holes, close it by tightening the screw. Wait until the oil flows from the other bleed
hole, then close this as well.
In other cases, prime as below:
•
CARE SHALL BE TAKEN TO ENSURE THAT THE BLEED HOLES ARE NOT DIRECTED TOWARDS THE OPERATOR OR
OTHER PERSONNEL.
•
Connect the tool to the air supply.
•
Keeping the trigger pressed, slightly loosen the Bleed Screw 18 (the closest to the front of the tool) until oil begins to flow.
•
Keep the trigger pressed until there is no air in the oil, then tighten the Bleed Screw 18.
•
Release the trigger.
•
Repeat the last three steps, with intervals of several seconds, to ensure that clean oil circulates and all air is removed.
The hydraulic circuit for the pull side is now free of air. The following removes air from the hydraulic circuit on the return side.
•
Keep the tool connected to the air.
•
Without pressing the trigger (the return hydraulic circuit already has pressure), slightly loosen the Bleed Screw 18 from the rear of
the tool until oil begins to flow.
•
When there is no air in the oil, tighten the Bleed Screw 18.
•
Operate trigger.
•
Repeat the last three steps, with intervals of several seconds, to ensure that clean oil circulates and all air is removed.
Ensure that the oil reservoir is not starved of oil, otherwise air will be drawn in to the system.
•
If necessary, refill the oil reservoir up to the level as indicated before.
To verify that the tool is correctly primed, measure the stroke. The piston stroke should be approximately 32mm and the piston should
always return fully.

priming oil to a level of 20 mm (0.8") below top of the reservoir.
