ADDING HYDRAULIC OIL:
a.
Place the driver in a vise in a vertical position with the handles up. Unscrew the
reservoir handle and remove the bladder plug. Open the turn screw to assure the ram
is fully extended.
b.
Fill the rubber bladder to the point of overflow with hydraulic oil.
c.
Purge air from the system: Pump the lever handle several times to remove air from
the pumping chamber. Close the turn screw until the ram completes its full travel.
Repeat as necessary.
Open the turn screw slowly so the ram extends slowly.
Rapid return of oil and air may cause the oil to overflow
the rubber bladder.
If this procedure fails to remove air, remove the bladder plug and open the turn screw.
Place thumb over the plug hole in the bladder and squeeze the bladder while pumping
the lever handle several times. Close the turn screw and pump the pump handle until
the ram completes its full travel. Repeat as necessary.
d.
Fill the rubber bladder to the point of overflow and replace the bladder plug. Wipe the
bladder clean of excess oil and reassemble the reservoir handle.
OIL LEAKS
a.
Check for external oil leaks
b.
Check that the turn screw and stem are closed tightly and seating properly.
c.
Remove the reservoir handle and check for oil leaks around the rubber bladder and
bladder plug.
Please wear the rubber gloves to avoid skin touching the oil directly, if touches it,
please wash the skin by soap and water quickly. In order to protect the
environment please drain the waste oil to the treatment center where was
approved by local or federal governments.
