Always
operate the system under no load
condition prior to the actual lift to ensure that no
air is trapped in the hydraulic circuit.
Do not
drop or place heavy objects on a
hydraulic hose as this will cause internal
damage to the hose which could result in
rupture when the hose is pressurized and could
result in serious damage to components, and
possible serious personal injury to operating
personnel.

Description:
HP110:
1.
The pump may be used either horizontally
or vertically with the hose end downwards.
The pump is equipped with a pressure relief
valve factory set at the maximum
operating pressure. Before use unscrew
transit plug and replace with breather on
the top of the tank. This will maximise the oil
volume available. See Figure 1.
2.
To advance the cylinder, turn the release
knob clockwise. Operate pump handle.
See Figure 2
3.
Note: The cylinder will automatically be
held in the advance position and will not
retract of its own accord.
4.
To retract the cylinder turn release knob
anti-clockwise slowly, ensuring that the
cylinder does not retract too fast as to
make the operation unsafe. See Figure 3.
