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.
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.
Relief Valve Adjustment:
1. Loosen lock nut counter-clockwise.
2. Using 4mm Allen Wrench turn clockwise to increase or
counter-clockwise to decrease pressure.
3. Tighten lock nut clockwise while holding pressure setting
with 4mm Allen Wrench.
