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.
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.
Refer to Section 2.0, Table 1 for the pressure
rating of your pump model. Do not connect a jack or
cylinder with a lower pressure rating. Never set a 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.
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
170°F [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.
