11.0 HYDRAULIC SYSTEM MAINTENANCE
WARNING
Failure to observe and comply with the following precautions
could result in death or serious personal injury. Property
damage could also occur.
• To avoid accidental starting, be certain that the pump power
cord is disconnected from the AC power supply before
performing any maintenance procedures.
• Be certain that all system hydraulic pressure is completely
relieved before performing any maintenance procedures.
Refer to information in Section 10.0.
11.1 Hydraulic Oil Information
Enerpac HF hydraulic oil (ISO Grade 32) is the recommended oil
for all E-Series pumps. This oil is suitable for most applications
and working environments.
NOTICE
• Use of oils other than Enerpac HF may result in damage to
pump hydraulic components and will void the Enerpac product
warranty. Enerpac recommends using only Enerpac HF oil in
the E-Series pumps.
• Never mix oils of different viscosities. Mixing oil viscosities
may result in damage to pump components and will void the
Enerpac product warranty.
11.2 Checking the Oil Level
1. Be sure that hydraulic torque wrench is fully retracted.
2. Be certain that pump is stopped and that all hydraulic
pressure is fully relieved before continuing this procedure.
Refer to Section 10.0.
3. Be sure that the pump is placed on a level surface.
4. Check the oil level indicator. Verify that the oil level is up to
the full mark. Refer to Figure 8.
If oil level is low: Add oil as described in Section 11.3. Refer
to Section 11.1 for oil specifications.
NOTICE
Be sure that the oil is clean. If the oil has a milky,
cloudy or dark appearance, it should be changed immediately as
described in Section 11.4.

11.3 Adding Oil
1. Be sure that hydraulic torque wrench is fully retracted.
2. Be certain that pump is off and that all hydraulic pressure is
fully relieved. Refer to Section 10.0 for additional information.
3. Disconnect pump AC power cord from electrical outlet.
4. Disconnect hydraulic hoses from pump.
5. With the pump in the normal (horizontal) operating position,
check the oil level in the oil level indicator. Use the diagram
in Figure 10 to determine the approximate amount of
additional oil that must be added.
6. Place the pump on a stable and level work surface, with the
front cover facing UP, and the rear cover supported by the
work surface. See Figure 9.
7. Using a clean rag, remove any dirt from the area around the
hydraulic reservoir drain/fill plug. Remove the drain/fill plug.
NOTICE
• Refer to Section 11.1 for oil specifications. Use only new oil
poured from a clean container.
• Always use a funnel when adding oil. To avoid spillage and to
ensure that pump internal venting functions properly during
filling, funnel neck outer diameter must not exceed 1/2 inch
[12 mm] or be less than 1/4" [6.3 mm]. Refer to Figure 9.
• Add oil only with the pump front panel facing up, and with the
pump positioned on a level surface.
• When the maximum oil level is achieved, an internal overflow tube
will direct oil to the concentric vents located around the oil drain/
fill port. Stop adding oil immediately when oil begins flowing from
these vents. Wipe up any spilled oil with a clean rag.
• Do not tilt or reposition the pump when adding oil. Overfilling
and oil leakage will result.
• Remove and dispose of any spilled oil in accordance with all
applicable laws and regulations.
