Replace shipping plug (red) with air vent plug (black) before use. 

4.3

 

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 @ 4-12 bar/60-175 psi to each power unit being 
operated.

4.4

 

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 – Bleeding Air from the System in the Maintenance Section. 

4.5

 

Check all system fittings and connections to be sure they are tight and leak free. 

4.6

 

Check oil level in reservoir before operating power unit.

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 

 

5.1

 

Connect air supply to the 1/4" NPT air nipple.
