Make hydraulic connections – Clean all areas around the oil port of power unit and
cylinder. Clean all hose ends, couplers and union ends. Remove the manifold plug and
connect the 3/8”NPTF oil output port with a 700 bar hydraulic hose.
4.3
Check all system fittings and connections to be sure they are tight and leak free.
4.4
Check oil level in reservoir before operating power unit.
4.5
Power connection – Confirm the power unit’s voltage is the same as the voltage being
supplied by the site, the source is a stable supply and that the motor is correctly
grounded.
Ensure power is switched off prior to connection of hoses and equipment to prevent
early pressurisation
4.6
Remove air from the system – Air can accumulate in the hydraulic system during the
initial setup or after prolonged use, causing the cylinder to respond slowly or in an
unstable manner. Should removal of air from power unit be required, please follow the
steps in 6.2 – Bleeding Air from the System in the Maintenance Section.

Operation
IMPORTANT:
Always monitor pressure, load or position using suitable equipment. Pressure may be
monitored by means of an optional manifold and gauge. Correct application position
can only be determined by the operator of the equipment
Never
set the relief valve to a higher pressure than the maximum rated pressure of the
power unit. Higher settings may result in equipment damage and/or personal injury
Do NOT
remove the relief valve
Do NOT
operate a power unit that is disconnected from the application. If operated in
this condition, the hose and connections will become pressurised. This increases the
chance of a burst hazard. Damage may also occur to the power unit and its
components
Although this power unit may be used at any angle, before use it must be secured or
supported to ensure that it does not slip and cause injury
This power unit is designed for indoor use, please protect from the elements if used
outside
The unlabelled second switch (below the ON switch) on the remote pendant is not
wired / does not work
