4.1
Familiarise yourself with the specifications and illustrations in this owner’s manual.
Know your pump, its limitations and how it operates before attempting to use. Refer to
the specification chart below or if in doubt, contact a Durapac representative.
4.2
Remove the manifold plug and then connect fluid output port to suitable fittings and
application/cylinder.
4.3
Check all system fittings and connections to be sure they are tight and leak free.
4.4
Check fluid level in reservoir before operating pump.
4.5
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 pump be required, please follow the
steps in 6.2 – Bleeding Air from the System in the Maintenance Section.

Operation
IMPORTANT:
Do NOT
add extensions to the pump handle. Extensions cause unstable pump
operation
In certain situations the pump handle can "kick back". Always keep your body to the
side of the pump, away from the line of force of the handle
Do NOT
operate a pump that is disconnected from application. If operated in this
condition, the hose and connections will become pressurised. This increases burst
hazard. Damage may occur to pump and its components
5.1
Before Using the Pump
