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.
IMPORTANT: Do not lift hydraulic
equipment by the hoses or swivel
couplers. Use the carrying handle or
other means of safe transport.
CAUTION: KEEP HYDRAULIC
EQUIPMENT AWAY FROM
FLAMES AND HEAT. Excessive
heat will soften packings and seals, resulting in
fluid leaks. Heat also weakens hose materials
and packings. For optimum performance do
not expose equipment to temperatures of
65°C [150°F] or higher. Protect hoses and
cylinders from weld spatter.
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.
WARNING:
Only use hydraulic
cylinders in a coupled system. Never
use a cylinder with unconnected
couplers. If the cylinder becomes extremely
overloaded, components can fail
catastrophically causing severe personal
injury.
WARNING: 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 centered on the cylinder
plunger. Off-center loads produce
considerable strain on cylinders and plungers.
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 plunger.
IMPORTANT: Hydraulic equipment
must only be serviced by a qualified
hydraulic technician. For repair
service, contact the Authorized ENERPAC
Service Center in your area. To protect your
warranty, use only ENERPAC oil.
WARNING: Immediately replace worn
or damaged parts by genuine
ENERPAC parts. Standard grade
parts will break causing personal injury and
property damage. ENERPAC parts are
designed to fit properly and withstand high
loads.
3.0 DESCRIPTION
Your Enerpac gauge is designed primarily to
function as a visual measuring device for
observing the hydraulic operating condition of
your system. The use of a hydraulic gauge is
recommended with every hydraulic system to
insure that the operating ratings of the
hydraulic components within the system are
not exceeded.
In high-production applications, once the
hydraulic system pressure settings have been
adjusted for production runs, your hydraulic
gauge should be disconnected from the
hydraulic system. This can be done by
