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 information about an 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.
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.
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 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.

    • M
      Monica ChangAug 11, 2025
      If your Enerpac Water Pump fails to maintain pressure, it could be due to an external hydraulic leak. Check all connections and tighten any that are leaking. Another possibility is an internal hydraulic leak. In this case, replace any damaged hoses or fittings. If the issue continues, have the pump repaired by a qualified hydraulic technician.

    How to fix low fluid output on Enerpac PUD1101E Water Pump?
    • L
      Lindsey HuynhAug 16, 2025
      Low fluid output in your Enerpac Water Pump can stem from several causes. First, ensure the fluid level is adequate by filling the reservoir to the proper level. Leaks in pump components can also reduce output; test to isolate any leaks and have the pump repaired by a qualified hydraulic technician. Additionally, a malfunctioning bypass valve or fluid intake screens clogged with debris on the piston blocks could be responsible. Inspect the intake screens and flush all components to remove contamination, replacing any damaged parts.

    Why does the cylinder on my Enerpac PUD1101E Water Pump advance and retract erratically?
    • M
      Michael WarrenAug 29, 2025
      If the cylinder on your Enerpac Water Pump advances and retracts erratically, it could be due to air in the system. Try removing the air by repeatedly opening and closing the tool until the operation becomes smooth. Another potential cause is an external leak in the system. Inspect all connections and tighten any that are loose. Also, an internal hydraulic leak may be the cause. Replace any damaged hoses and fittings. If the problem persists, have the pump inspected and repaired by a qualified hydraulic technician.

    Why won't the cylinder on my Enerpac PUD1101E advance or retract?
    • H
      Helen LongSep 3, 2025
      If the cylinder on your Enerpac Water Pump is not advancing or retracting, several factors could be the cause. Start by checking the fluid level; if it's low, fill the reservoir to the correct level. Another common issue is a clogged intake screen, which you should clean or replace. Also, make sure the valve is in the correct position; shift it to the pressure position. If these steps don't resolve the problem, the valve may have failed, requiring repair by a qualified hydraulic technician.
