HYDRAULIC SEALED HAND PUMPS
OPERATOR INSTRUCTION MANUAL
PAGE 22
Problem: The tool the hand pump is driving is advancing but does not reach full pressure
Air could be present in
the hydraulic system
Use the airlock removal
procedure as follows:
1.
Connect the hand pump to the
tool with the hydraulic hose
2.
Close the release valve on the
pump, and prime the pump
until the hydraulic cylinder
is fully extended and a small
pressure is achieved
3.
With the hand pump held
above the tool and the tool
in an upright position, open
the release valve causing any
air that is within the system
to be forced up through the
pump and vented into the oil
reservoir
4.
Repeat steps 1 - 3 three or
four times to ensure that all air
is removed from the system
and the tool will reach full
working pressure
5.
Disconnect the hand pump
from the hydraulic hose, grip
the baseplate of the hand
pump body in a vice with the
pump body vertical and the
main handle at the top
6.
Remove the four nuts holding
the main handle and lift off
7.
Grip the refilling plug with
pliers and extract it by pulling
and twisting simultaneously.
Ensure the reservoir body is
held down when removing the
refilling plug as pulling up on
the reservoir body will release
the bladder within, and oil will
spill out.
8.
Fill the reservoir to the top with
a good quality hydraulic oil of
the grade 15 cSt
9.
Reinsert the refilling plug, wipe
away any oil, and reassemble
by reversing the disassembly
process
