• Continue until oil fl owing from both bleed holes is free of air bubbles, (ensure that the reservoir is not starved of oil,
otherwise air will be drawn into the system introducing air bubbles in the oil stream).
• When air free oil is fl owing from both bleed holes, operate the trigger and tighten the front bleed screw with an Allen
key. Release the trigger and tighten the rear bleed screw with an Allen key.
• If necessary, top up the oil reservoir.
9.4 ALTERNATIVE PRIMING PROCEDURCE
CAUTION - CONNECT AIR SUPPLY (this causes the piston to bottom, allowing more priming oil into the tool).
CAUTION - All operations should be carried out on a clean bench, with clean hands, in a clean area.
CAUTION - 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 21 and 22, item number 28* refers to
the General Assembly of Cabinet and Parts List on pages 23and 24.
•
Prior to starting the priming procedure, obtain a suitable container to collect excess oil.
• Disconnect the air supply and undo the intensifi er Oil Reservoir Plug 28*.
• Top up the reservoir in the cabinet with VG32 Hyspin® priming oil to a level of 20 mm (0.8”) below top of the reservoir.
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 fl ows under gravity.
• Once the oil starts to fl ow from one of the bleed holes, close it by tightening the screw. Wait until the oil fl ows 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
fl ow.
• 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 fl ow.
• 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 into the system.
• If necessary, refi ll 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.
