2.0 Receiving Instructions
It is recommended prior to use that an inspection be done by qualified personnel and that any
missing or damaged parts, decals, warning/safety labels or signs are replaced with Durapac
authorised replacement parts only. Any power unit that appears to be damaged in any way, is worn,
leaking or operates abnormally should be removed from service immediately until such time as
repairs can be made. Any power unit that has been or suspected to have been subject to a shock
load should be removed from service immediately until inspected by a Durapac authorised service
centre. Owners and operators of this equipment should be aware that the use and subsequent
repair of this equipment may require specialised training and knowledge.
3.0 Safety
Save these instructions. For your safety, read and understand the information contained within. The

Instruction Manual
Do NOT handle pressurised hoses. Escaping oil under pressure can penetrate the skin
causing serious injury. If oil is injected under the skin, see a doctor immediately
Stay clear of loads supported by hydraulics. A cylinder, when used as a load lifting
device, should never be used as a load holding device. After the load has been raised
or lowered, it must always be blocked mechanically
WARNING:
The system operating pressure must not exceed the pressure rating of the lowest
rated component in the system. Install pressure gauges in the system to monitor
operating pressure. It is your window to what is happening in the system
Always wear protective gear when operating hydraulic equipment. The operator must
take precaution against injury due to failure of the tool or work piece(s)
Do NOT hold or stand directly in line with any hydraulic connections while pressurising
Do NOT attempt to disconnect hydraulic connections under pressure. Release all line
pressure before disconnecting hoses
All personnel must be clear before lowering load or depressurising the system
Do NOT attempt to lift a load weighing more than the capacity of the cylinder
IMPORTANT:
If at any stage, the safety related decals become hard to read, these must be replaced
Minimum age of the operator must be 18 years. The operator must have read and
understood all instructions, safety issues, cautions and warnings before starting to
operate the equipment. The operator is responsible for this activity towards other
persons
Do NOT lift hydraulic equipment by the hoses or couplers. Use the carrying handle or
other means of safe transport
Hydraulic equipment must only be serviced by a qualified hydraulic technician. For
repair service, contact the Durapac authorised service centre in your area. To protect
your warranty, use only high quality hydraulic oil
CAUTION:
KEEP HYDRAULIC EQUIPMENT AWAY FROM FLAMES AND HEAT. Hydraulic fluid can
ignite and burn. Excessive heat will soften packings and seals, resulting in fluid leaks.
Heat also weakens hose materials and packings. For optimum performance do not
expose equipment to temperatures of 65°C (150°F) or higher. Protect all equipment
from weld spatter
No alteration should be made to this device
3.1 Hydraulic Power Units
Ensure that the air source is SWITCHED OFF prior to connection of hoses and other
hydraulic equipment or prior to any repairs being undertaken
Do use a gauge or other load measuring instrument to verify load
PAT-1114 Power Units - V1.1 www.durapac.com Page 3 of 15
Instruction Manual
Do NOT exceed the rated capacity of the power unit or any equipment in the system.
Burst hazard exists if connection pressure exceeds rated pressure
Regularly inspect power unit, hoses and connections before each use to prevent
unsafe conditions from developing. Do NOT use if they are damaged, altered or in
poor condition. Do NOT operate the system with bent or damaged coupler or
damaged threads
Do NOT subject the power unit and its components to shock loads
Use only Durapac approved accessories and components
Ensure that the chosen application is stable to work on and around
Do NOT connect to an application which can return more oil to the reservoir than the
power unit reservoir can hold
Do NOT connect power unit to a hydraulic system that is powered by another pump
3.2 Hydraulic Hoses & Fluid Transmission Lines
Avoid short runs of straight line tubing. Straight line runs do not provide for expansion
and contraction due to pressure and/or temperature changes
Ensure that the minimum bending radius is greater than 120 mm
Reduce stress in tube lines. Long tubing runs should be supported by brackets or clips.
Before operating the power unit, connections should be tightened securely and leakfree. Over tightening can cause premature thread failure or high pressure fittings to
burst
Should a hydraulic hose ever rupture, burst or need to be disconnected, immediately
shut off the power unit and release all pressure. Never attempt to grasp a leaking
pressurised hose with your hands. The force of escaping hydraulic fluid can inflict
injury
Do NOT subject the hose to potential hazard such as fire, sharp objects, extreme heat
or cold or heavy impact
Do NOT allow the hose to kink, twist, curl, crush, cut or bend so tightly that the fluid
flow within the hose is blocked or reduced. Periodically inspect the hose for wear
Do NOT pull, position or move setup by the hose
Hose material and coupler seals must be compatible with the hydraulic fluid used.
Hoses also must not come in contact with corrosive materials such as battery acid,
creosote-impregnated objects and wet paint. Never paint a coupler or hose
FAILURE TO HEED THESE WARNINGS MAY RESULT IN PERSONAL INJURY AS WELL AS PROPERTY DAMAGE.
4.0 Installation
IMPORTANT: Always secure threaded port connections with high grade, non-hardening pipe
thread sealant. Teflon tape can be used if only one layer of tape is used and it is applied

Instruction Manual
IMPORTANT:
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
pressure before loosening any hydraulic connection in the system
When only using one hydraulic torque wrench, cover the unused hydraulic coupling

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.
Figure 1 – Hydraulic Connectors
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.
