the concentric vent openings around the fill opening are not
plugged with dirt. Venting will occur through these openings
as oil is added in step 6.
NOTICE
Refer to Section 8.2 for hydraulic oil requirements.
6. SLOWLY add Enerpac oil while watching the oil level through
the funnel stem. To avoid spillage, stop pouring immediately
when oil level reaches the top of the oil fill tube.
7. Remove funnel from oil fill opening.
8. Reinstall O-ring and oil fill plug. Be sure fill plug is fully
installed. Torque to 40 - 50 in-lbs [4.5 - 5.7 Nm].
9. Reinstall the battery pack.
8.4 Oil Change
Change the hydraulic oil in the pump reservoir at least once
a year, or whenever it is suspected that the oil has become
contaminated.
The pump contains a rubber bladder style reservoir. To properly
drain and refill the reservoir, change the oil as described in the
following steps. See Figure 13.
1. Be sure hydraulic cylinder or tool is fully retracted.
2. Rotate the control valve lever back and forth several times
between the “A” and “B” positions to remove any trapped
pressure.
3. Move the trigger lock to the locked position.
4. Disconnect hoses from ports “A” and “B” of pump.
5. Attach an open-ended hose to the pump “A
” port. Place the
open end of the hose in a suitable pan or container that is
large enough to collect all the used oil.
NOTICE XC-1401 models have a one liter [60 in³] reservoir.
XC-1402 models have a two liter [120 in³] reservoir. Be sure the
pan or container is large enough to hold all the drained oil.
6. To prevent dirt entry, seal the pump “B
” port with a metal
plug or closed coupler.
7. Be sure that oil fill plug is fully installed in the pump oil fill
opening. It will be removed later, but must remain installed
at this time.
8. Move the trigger lock to the unlocked position.
9. Move the control valve lever to the “A ” advance position.
10. Pull the trigger switch upward to start the pump motor.
Continue running the motor until oil stops flowing from the
open-ended hose. Then, release the trigger switch.
NOTICE Dispose of used oil in accordance with all applicable
laws and regulations.
11. Remove the battery pack from the pump.
12. Remove the open-ended hose from the pump “A” port. To
prevent dirt entry, seal the “A ” port with a metal plug or
closed coupler.
13. Slowly fill the reservoir with new Enerpac oil. Refer to
Section 8.2 for hydraulic oil requirements and Section 8.3
for detailed oil fill instructions. Usable oil capacity will be
slightly less than the rated reservoir size for your pump
model.
14. After adding oil, reconnect the cylinder or tool and reinstall
the battery pack. Run the pump and cycle the cylinder or
tool several times to bleed any trapped air from the system.
Refer to Section 7.6 for additional information.
15. Check oil level again after cycling the cylinder or tool. With
the cylinder or tool fully retracted, verify that oil level has not
dropped. Add additional oil if level is low.
8.5 Relief Valve Pressure Adjustment
The pump contains a user-adjustable pressure relief valve that is
factory set at 9950-10,300 psi [686-710 bar]. Check and adjust
the setting as described in the following steps. See Figure 14.
1. Be sure hydraulic cylinder or tool is fully retracted.
2. Rotate the control valve lever back and forth several times
between the “A” and “B” positions to remove any trapped
pressure.
3. Remove the battery from the pump.
4. Remove hydraulic hoses from pump ports “A” and “B”.
5. Connect a 0-15,000 psi [0-1000 bar] pressure gauge to the
pump “A” port.
