carefully, two threads back, to prevent the tape from being introduced into hydraulic system,
which could cause jamming of precision-fit parts
4.1 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.
4.2 Ensure that there is adequate oil in the reservoir to perform the required function.
Ideally the gauge should not read less than 1/3. If this is the case see section 6.1
Adding Hydraulic Fluid.
4.3 Hydraulic connections – check all system fittings and connections to be sure they are
tight and leak free.
The wrench and power unit are connected by a 700 bar operating pressure, twin-line
hose assembly. Each end of the hose will have one male and one female connector to
ensure proper connection between the power unit and the wrench.

4.4 Air connection - connect suitable air supply to air input port. Ensure that your air source
can dedicate 1,400 Lpm @ 6.2 bar to each power unit being operated.
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.


To reduce the risk of personal injury and/or property damage, Hydraulic connections
must be securely fastened before building pressure in the system. Release all system
