Instruction Manual
DANGER:
To avoid personal injury keep hands and feet away from work area during operation
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 supported 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 appropriate personal protective equipment (PPE) 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

Instruction Manual
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 Cylinders
Do NOT overload equipment. Overloading can cause equipment failure and possible
personal injury
This device is not suitable for use as a support device! As the system load is lifted,
use blocking and cribbing to guard against a falling load
BE SURE SETUP IS STABLE BEFORE LIFTING LOAD. Cylinders should be placed on a
flat surface that can support the load. Where applicable, use a cylinder base for
added stability. Do not weld or otherwise modify the cylinder to attach a base or
other support
Avoid situations where loads are not directly centred on the cylinder piston. Off-
centre loads produce considerable strain on cylinder and pistons. In addition, the
load may slip or fall, causing potentially dangerous results
Distribute the load evenly across the entire saddle surface. Always use a saddle to
protect the piston (if one is provided)
USE ONLY RIGID PIECES TO HOLD LOAD. Carefully select steel or wood blocks that
are capable of supporting the load. Never use a hydraulic cylinder as a shim or
spacer in any lifting or pressing application
Never pressurise uncoupled couplers. Only use hydraulic equipment in a coupled
system
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
Reduce stress in tube lines. Long tubing runs should be supported by brackets or
clips. Before operating the pump, connections should be tightened securely and
leak-free. 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 pump 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
RG Series SA CT Cylinder - V1.4 www.durapac.com Page 4 of 26
Instruction Manual
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
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
WARNING: When hoisting the cylinder, use all of the eye bolts. Failure to do so could cause the
cylinder to drop unexpectedly. Lifting straps must be at a 45 degree or greater angle from
horizontal. See Figure 1 (below)
Figure 1 – Hoisting Cylinder
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
carefully, two threads back, to prevent the tape from being introduced into hydraulic system,
which could cause jamming of precision-fit parts
CAUTION: DO NOT allow the piston rod to rotate when installing adaptors. Damage to the
spring may prevent piston rod retraction
4.1 Know your cylinder, its limitations and how it operates before attempting to use. If in
doubt, contact Durapac.
4.2 Make hydraulic connections; use a pump release valve or a 3-way valve and one hose
for a single-acting cylinder.
IMPORTANT: Fully hand-tighten all couplers. Loose coupler connections will block
the flow of oil between the pump and the cylinder
4.3 Check all system fittings and connections to be sure they are tight and leak free.
4.4 Check oil level in reservoir before operating pump.
RG Series SA CT Cylinder - V1.4 www.durapac.com Page 5 of 26
Instruction Manual
IMPORTANT:
Always use a flat, hard surface as a cylinder support plate
Collar threads are rated for the full capacity of the cylinder when fully engaged in
attachments
Cylinder gland nut/stop ring is designed to take the full load, to reduce cylinder wear,
use less than the full stroke where possible
4.5 Remove air from the system – Position the cylinder so that the piston rod is pointed
down and the cylinder is lower than the pump. Advance and retract the cylinder
several times, avoiding pressure build-up. Air removal is complete when the cylinder
motion is smooth.
5.0 Operation
For complete operating instructions refer to the instruction sheet included with each pump.
5.1 Advancing and retracting the cylinder
The RG Series cylinders are a spring return cylinder and the speed of retraction is
affected by the length of the hose and other restrictions in the line.
Shift the valve on the pump to the advance position and run the pump to advance the
cylinder. To retract the cylinder, shift the valve to the retract position.
Figure 2 – RG Series Sectional Drawing
5.2 Side Load
Eliminate the presence of side load forces when using high tonnage cylinders. Side load
can occur through:
5.2.1 An eccentric load on the piston rod.
5.2.2 A horizontal load on a structure.
5.2.3 A structure and/or cylinder misalignment.
RG Series SA CT Cylinder - V1.4 www.durapac.com Page 6 of 26
5.2.4 Non synchronised lifting actions
IMPORTANT:
Use only good quality hydraulic fluid. Do NOT use brake fluid, transmission fluid,
turbine oil, motor oil, alcohol, glycerine etc. Use of anything other than good quality
hydraulic oil will void warranty and damage the cylinder and application. We
recommend Durapac Hydraulic Oil or equivalent
Equipment must only be serviced by a qualified hydraulic technician. For repair service,
contact your local Durapac authorised service centre
Damage to hydraulic hoses may not be detected during visual inspections. For this
reason, Durapac recommends that hydraulic hoses be replaced on a regular basis
Tighten connections as needed. Use non-hardening pipe thread compound when
servicing connections
5.2.5 Non stable cylinder base support.
To reduce cylinder offset loading, optional tilt saddles are available. Always use grease
underneath swivel saddles.
6.0 Maintenance
Instruction Manual
Figure 3 – Tilt Saddle.
Dirt, sand, etc. will quickly ruin any hydraulic system. Ensure that couplings are clean and free of
foreign matter. After each use, clean couplings and attach dust caps.
Maintenance is required when wear or leakage is noticed. Periodically inspect all components to
detect any problem that may require service and maintenance.
6.1 Check for loose connections and leaks.
6.2 Replace damaged parts immediately.
6.3 Do not exceed oil temperature above 60
o
C.
6.4 Keep all hydraulic components clean.
6.5 Use dust caps when cylinder is disconnected from the hose. Keep entire cylinder clean
to prolong cylinder life.
6.6 Wipe thoroughly clean and store cylinders upright (to prevent seal distortion) in a
clean, dry environment. Avoid temperature extremes.
6.7 Change hydraulic oil in your system as recommended in the pump instruction sheet.
