Always operate the system under no load condition
prior to the actual lift to ensure that no air is
trapped in the hydraulic circuit.
Do not drop or place heavy objects on a hydraulic
hose as this will cause internal damage to the hose
which could result in rupture when the hose is
pressurized and could result in serious damage to
components, and possible serious personal injury
to operating personnel.
Lifting cylinders should always be placed on a flat
even surface that can support the load to be
applied.
Avoid lifting loads that are not central to the lifting
piston. Avoid offset loading as this can damage the
cylinder bores and piston rods, and also lead to
unstable load lifting.
Where applicable, use an additional cylinder
support base to assist in supporting the load to be
lifted.
Do not weld items to the cylinder or modify the
cylinder in any way from its delivered condition.
This will invalidate your warranty, and could lead to
serious personal injury.
Only use hydraulic cylinders in a completed, tested
coupled system. Never attempt to use a cylinder
that is not correctly coupled to its operational
pump.
If hydraulic cylinders are overloaded to
extreme degrees, this could in extreme cases
to component failure and may lead to serious
personal injury.

INSTRUCTION MANUAL – HYDRAULIC CYLINDERS:
4.0 Installation – Connection and Bleeding:
Ensure that the hydraulic pump being used is
suitable for the cylinder/s it is to be connected to.
For single acting cylinders (one pressure coupling
connection), a hydraulic pump with a 2 way or 3
way valve and one single correctly rated hose must
be used.
For double acting cylinders (two pressure coupling
connections), a hydraulic pump with a 4 way valve
and two correctly rated hoses must be used.
DANGER:
Double Acting cylinders must always have
both coupling connections securely and correctly
made prior to use. Never attempt to pressurize a
double acting cylinder, if only one connection has
been made.
Connect the hoses between the cylinder and the
pump ensuring that the coupling/s are fully hand
tightened only. Never use wrenches to attempt to
connect the coupling/s, incorrectly connected
coupling/s is one of the most common causes of
faulty operation.
Before putting the cylinder into operation, it is
important that the system is bled to ensure that all
the air is removed.
To remove air from the cylinder proceed as below:-
Single Acting Cylinders: Position the cylinder below
the level of the hydraulic pump with the piston of
the cylinder pointed downwards (as in A, in the
diagram above.) Fully extend and retract the piston
