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:
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
Do not lift hydraulic

4.0 INSTALLATION
1. Install the manifold so that the direction of flow is
from the center (inlet) hole to the valve outlet
holes on the opposite side.
2. Use correct fittings. AM-2 and AM-4 manifolds
have 3/8"NPTF female connections. Ensure
standard steel hex plugs (Enerpac part number
R515245-2) are in place for any unused outlets.
3. Use 1-1/2 wraps of Teflon tape (or similar thread
sealant) on fittings, leaving the first complete
thread free of tape or sealant to prevent sealant
from entering the hydraulic system.
fittings securely.
CAUTION: Connections should be snug
and leak-free. Overtightening connections
promotes thread failure and may cause
high pressure fittings to rupture at less
than rated capacity.
WARNING: Shut-off and safety valves
should be close-coupled to cylinders.
NEVER allow pressurized hoses in a load-
holding circuit.
4. Tighten the valve handle to close the respective
valve. Loosen handle to open valve. Handles may
be locked into position by tightening the set screws.
WARNING: Turn handles only as far as the
stops. Overtightening or subjecting the
handles to excessive force will weaken
and strip internal spindle threads, creating
a safety hazard. Use only fingers to tighten knurled
knobs. NEVER use extension handles.
