Shipping damage is not covered by warranty. If
shipping damage is found, notify carrier at once. The
carrier is responsible for all repair and replacement
costs resulting from damage in shipment.

SAFETY FIRST

2.0 SAFETY ISSUES

Read all instructions,
warnings and cautions

carefully. Follow all safety
precautions to avoid personal injury or property
damage during system operation. Enerpac cannot be
responsible for damage or injury resulting from unsafe
product use, lack of maintenance or incorrect product
and/or system operation. Contact Enerpac when in
doubt as to the safety precautions and operations. If
you have never been trained on high-pressure
hydraulic safety, consult your distribution or service
center for a free Enerpac Hydraulic safety course.

Failure to comply with the following cautions and
warnings could cause equipment damage and
personal injury.

A CAUTION is used to indicate correct operating or
maintenance procedures and practices to prevent
damage to, or destruction of equipment or other
property.

A WARNING indicates a potential danger that
requires correct procedures or practices to avoid
personal injury.

A DANGER is only used when your action or lack of
action may cause serious injury or even death.

WARNING: Wear proper personal
protective gear when operating hydraulic
equipment.

WARNING: Stay clear of loads supported
by hydraulics. A cylinder, when used as a
load lifting device, 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.

DANGER: To avoid personal injury
keep hands and feet away from cylinder
and workpiece during operation.

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. The cylinders are
designed for a max. pressure of 700 bar [10,000 psi].
Do not connect a jack or cylinder to a pump with a
higher pressure rating.

DANGER: Never set the 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. Do not remove relief valve.

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 back­pressure. 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.

CAUTION: Always use the handle to carry

the pump. Carrying the pump by the hose

may damage the hose and/or the pump.

3.0 DESCRIPTION

3.1 Models P-141, 1001; P-142, 1002;
P-202; P-391, 1004; P-392, 1005; P-802;
P-842

Figure 1 and the corresponding table show the main
components of hand pump models P-141, P-142, P­202, P-391, P-392, P-802, and P-842. The dual­purpose vent/fill cap acts as a pressure relief valve in
case of accidental reservoir pressurization. To
provide an access port at the rear of the reservoir for
remote valves, use a return-to-tank kit. See the Table
1 for kit model numbers.

3.2 Models P-18/P-39, 1003/P-80, 1006/
P-84/P-801, P-77

Figure 2 and the corresponding table below show the
main components of these hand pump models.
Model P-84 is equipped with a 4-way, 3-position
valve for use with double-acting cylinders. To convert
models P-18 or P-39 to foot operation, order Kit PC-10.

WARNING: These pumps are operated

with a non-vented reservoir. If the
reservoir is subjected to high pressure,

the casing may rupture, causing
personal injury and/or equipment damage.
NEVER attempt to return more oil to the reservoir
than it is capable of holding.
