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
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.
