Remove air from the pump
– 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 pump be required, please follow the
steps in 6.2 – Bleeding Air from the System in the Maintenance Section.

Check oil level in reservoir before operating pump.

Operation
IMPORTANT:
Always monitor pressure, load or position using suitable equipment. Pressure may be
monitored by means of an optional manifold and gauge. Do not load a hydraulic
application (cylinder, spreader etc) to more than 80% of its rated capacity. 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
Never operate a pump that is not connected to an 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 pump and its components

To Start the Air Motor
IMPORTANT
: If the ON/OFF (blue) sleeve is switched ON, once connected to the
intended air source, the pump will be energised and oil will flow from the pump to the
application. Ensure the operator is aware that the application will be pressurised
immediately upon connecting to the air source
5.1.1
Ensure the ON/OFF (blue) sleeve is in the OFF position (away from the pump
– see Figure 2).
Figure 2 - DPR-223 - ON/OFF Sleeve
5.1.2
Ensure the lever is in the ‘2’ (hold/neutral) position (see Figure 3).
