IMPORTANT NOTICE
FR
The purpose of this use and maintenance manual is to provide
useful information but also to avoid risks and dangers during
use. Compliance with the instructions contained in this use and
NL
maintenance manual ensures an increase in useful life and thus a
reduction of the hydraulic cylinders repair costs.
Visually inspect the product to identify any shipping damage and, if
ES
any, promptly notify the shipper. Damage incurred during shipping
is not covered by warranty.

WARNING! This equipment is not a lifting device!
SAFETY PRECAUTIONS
PL
Carefully read all instructions, warnings and precautions.
During system operation, observe all safety regulations to avoid
injury or equipment damage. In case of doubt regarding safety or
DA
applications, contact WÜRTH. Failure to observe these precautions
could result in serious equipment damage and personal injury.
PRECAUTION: indicates correct operating or maintenance
EL
procedures to avoid damage to the equipment or to the surrounding
environment:
•
Always check the integrity of the accessories connected to the
cylinder as: tube, couplers, pressure gauge, pump, etc..;
•
Avoid bending and rolling the hose during use, it could be
irreparably damaged inside or create pressure fluctuations
during operation;
•
Do not drop heavy loads on the hose and prevent crushing
of any kind such as to compromise the integrity of the metal
reinforcement inside the hose;
•
Never lift the cylinder by the hose or by the coupler, but by
the body where it is fixed;
•
Keep the hydraulic equipment away from flames, heat sources
and sparks;
•
Do not use the cylinder out of the temperature range indicated
in Table A;
•
Be sure to use hydraulic fluid compatible with the gaskets
mounted in the cylinder, see operating temperatures and
viscosities in Table A;
•
Keep the coupler (quick-connect coupling) clean and close
with a special cap every time the hose is disconnected.
WARNING: Indicates a potential hazard that requires putting into
practice the correct procedures to avoid accidents:
•
During the equipment operation, handling and maintenance,
always wear personal protective equipment (gloves against
mechanical hazards and safety glasses with side protection);
•
Use the hydraulic cylinders only if the coupler was duly
inserted in the tube;

Never exceed the nominal capacity of cylinder pressure, both
the charge pressure and the hydraulic circuit pressure (700
bar);
Use only pumps with maximum pressure not exceeding 700
bar;
Install a pressure gauge between the cylinder and the pump
to monitor the operating pressure;
Use rigid blocks (steel or wood) to be placed under or above
the cylinder capable of withstanding the maximum load of the
cylinder;
Do not use the cylinder as a shim or as a wedge;
Before use, always place the cylinder on a flat surface and
make sure that the configuration of stressed components is
stable;
Distribute the load evenly over the entire surface of the head
of the rod (piston) to avoid misalignment or situations that
could cause slippage of the stressed parts;
Worn or damaged parts should be immediately replaced the
with original WÜRTH spare parts.
DANGER: Indicates a situation in which an action or lack of
Keep hands and feet away from the cylinder and the stressed
components to prevent personal injury;
Do not manoeuvre the tubes under pressure, the sudden
release of oil could tear the skin, causing serious injury, in
which case you should promptly consult a physician.
Actuate the exhaust valve of the pump always in a gradual
manner such that the components stressed by the movement of
the cylinder do not have counterstrokes and sudden failure.
Always wear the personal protective devices indicated.
