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 INSTALLATION
3.1 Air Connection
These pumps require 100 psi air at 40 scfm. Attach incoming air
supply to .375-18 NPT port on filter/lubricator. See Figure 1.
Figure 1
3.2 Hydraulic Connections
1. Couple hoses to torque wrench as shown in Figure 2. Rotate
coupler lock rings. When using the Enerpac pump and torque
wrench combination, Enerpac hoses and couplers are
designed so that the advance port can only be connected to
the wrench advance port, and the retract port can only be
connected to the wrench retract port.
WARNING: To ensure proper operation, avoid kinking
or tightly bending hoses. If a hose becomes kinked or
otherwise damaged, it MUST BE replaced. Damaged
hoses may rupture at high pressure causing personal injury.
WARNING: Attempting to couple a hose to the pump
or torque wrench while coupler is under pressure can
result in fluid leakage or personal injury.
3.3 Oil Level
Check oil level in reservoir. Oil level should be one inch below
vent/fill plug opening. If necessary, add hydraulic oil to bring oil
level up to one inch below the vent/fill opening.
NOTE: Use only approved hydraulic oil. Use of any other oils or
fluids may damage pump or seals and will void the warranty on
your pump.
CAUTION: Add oil only when all system components
are in the retract position, or the system will contain
more oil than the reservoir can hold.
