1.0 SAFE OPERATING PROCEDURES AND SAFETY
PRECAUTIONS
Read all DANGER, WARNING and CAUTION statements
carefully. Follow any recommended safety precautions
to avoid personal injury or damage to the unit.
LARZEP,
S.A
. cannot be responsible for any damage or injury from
unsafe use, lack of maintenance or incorrect operation.
In the event any questions or concerns arise, contact
LARZEP, S.A
. or a local distributor for clarification.
DANGER
Is only used when your action or lack of
action may cause serious injury or even
death.
WARNING
Indicates a potential danger that requires
correct procedures or practices to avoid
personal injury.
CAUTION
Is used to indicate correct operating or
maintenance procedures and practices
to prevent damage to, or destruction of
equipment, or other property.
Failure to comply with the following safety precautions
could cause equipment damage, property damage or
personal injury.
DANGER
To avoid personal injury, keep hands and
feet away from cylinder and work-piece during operation.
DANGER
Do not handle pressurized hoses. Escaping
oil under pressure can penetrate the skin, causing serious
injury. If oil is injected under the skin, see a doctor
immediately.
DANGER
Only use double-acting hydraulic cylinders
in a coupled system. Never use a cylinder with unconnected
couplers. If the cylinder becomes severely overloaded,
components can fail catastrophically causing severe
personal injury or death.
WARNING
Wear proper personal protective gear when
operating hydraulic equipment.
WARNING
Stay clear of loads supported by hydraulics.
A cylinder is only a load lifting device. Cylinders should
never be used as a load holding device unless they are
equipped with a lock nut, cribbing blocks or U-rings to
provide mechanical load holding. Cylinders without these
features should never be used as a load holding device.
After the load has been raised or lowered, it must always
be blocked mechanically.
WARNING
USE ONLY RIGID PIECES TO HOLD LOADS.
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.
WARNING
Do not exceed equipment ratings. Never
attempt to lift a load weighing more than the capacity of
the cylinder. Overloading causes equipment failure and
possible personal injury. The Larzep hand pumps are
designed for a maximum pressure of 700 bar. Do not
connect a jack or cylinder to a pump with a higher pressure
rating. Never set the relief valve to a higher pressure than
the maximum rated pressure of the pump. Higher settings
may result in equipment damage and/or personal injury.
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.
CAUTION
Avoid damaging hydraulic hose. Avoid sharp
bends and kinks when routing hydraulic hoses. Using a
bent or kinked hose will cause severe back-pressure.
Sharp bends and kinks will internally damage the hose,
leading to premature hose failure. Do not drop heavy
objects on hose. A sharp impact may cause internal
damage to hose wire strands. Applying pressure to a
damaged hose may cause it to rupture.
WARNING
Keep hydraulic equipment away from flames
and heat. Excessive heat will soften seals, resulting in fluid
leaks. Heat also weakens hose materials. For optimum
performance do not expose equipment to temperatures of
65°C or higher. Protect hoses and cylinders from weld
spatter.
IMPORTANT
Do not lift hydraulic equipment by the hose
or swivel couplers. Use the carrying handle or other means
of safe transport.
