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 catastrophi-
cally 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 an ENERPAC authorized
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 prop-
erty 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.

Figure 1
The P-392FP is a two-speed pump which can be used to
power single-acting cylinders and tools with an oil
capacity up to 490 cm³. It has an internal pressure relief
valve for overload protection. For dimensions see Figure 1.
Figure 2 shows the specifications of the pump.
WARNING: The P-392FP is 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.
4.0 INSTALLATION
4.1 Connecting the Pump
1. Thread hose into pump outlet. Use 1 1/2 wraps of Tef-
lon tape (or suitable thread sealant) on hose fitting,
leaving the first complete thread free of tape to ensure
that tape does not shed into hydraulic system, causing
damage. Trim loose ends.
2. Install a pressure gauge in-line from the pump for add-
ed safety and better control.
3. Connect the hose(s) to your cylinder or tool.
NOTE : For single-acting cylinders, connect one hose
from the pump to the cylinder. For double-acting
cylinders, connect two hoses. Connect one hose from
the pressure port of the pump to the pressure port of
the. cylinder. Connect another hose from the retract
port of the pump to the retract port of the cylinder.
4.2 Pump Venting
The P-392FP is 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.
5.0 OPERATION
5.1 Before Using the Pump
1. Check all system fittings and connections to be sure
they are tight and leak free.
2. Check oil level in reservoir before operating pump. See
paragraph 7.1, “Adding Oil to the Pump” on page 3.
CAUTION: NEVER add extensions to pump
handle. Extensions cause unstable pump
operation.
WARNING: In certain situations the pump handle
can “kick back”. Always keep your body to the
side of the pump, away from the line of force of
the handle.
NOTE: To reduce handle effort at high pressure, take short
strokes. Maximum leverage is obtained in the last 5° of
stroke.
