RG Series SA CT Cylinder - V1.4 www.durapac.com Page 4 of 26
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
