– 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. Load may be monitored by
means of a load cell and digital indicator. Correct application position can only be
determined by the operator of the equipment
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
