Familiarise yourself with the specifications and illustrations in this owner’s manual.
Know your power unit, its limitations and how it operates before attempting to use.
Refer to the specification chart below or if in doubt, contact a Durapac representative.

Air Connection -
Remove plastic cap, connect suitable air supply to air input port. Air
input port is designed to fit the popular 1/4" NPT air nipple (not included). Ensure that
your air source can dedicate 7.8 cfm @ 3-8 bar/45-116 psi to each power unit being
operated.
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 the power unit.

Remove air from the power unit

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

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
