9. Remove the oil fi ll plug and add Enerpac HF hydraulic oil as
required. Use a funnel to avoid spillage. Oil level should be
approximately 1 inch [25 mm] below top of reservoir, with
cylinder fully retracted and air motor turned off . See Figure
11 for oil level diagram.
NOTICE
• Reservoir is vented. To prevent oil leakage through the air
breather, do not fi ll reservoir completely to the top.
• To help avoid accidental overfi lling of reservoir, always make
sure that cylinder is fully retracted before checking oil level or
adding additional oil.
• If Enerpac HF is not available at the worksite, use an equivalent
hydraulic oil that meets the specifi cations shown in Table 8.
10. Clean the oil fi ll plug and apply thread sealant to the threads.
Reinstall oil fi ll plug.
WARNING In the following step, it will be necessary to
extend and retract the cylinder several times. Stay clear of
the cylinder and related components. Keep hands and fi ngers
away from pinch and crush points. Serious personal injury
could occur if these precautions are not observed. Refer to
Section 1.3 of this manual for additional hazard information.
11. With no load on the jack, extend and retract the cylinder
several times to check for proper operation, and to remove
any trapped air in the hydraulic system.
12. With the cylinder fully retracted and the pump motor off ,
re-check oil level to be sure that it has not dropped. Add
additional oil if required. See Figure 11 for oil level diagram.
13. Reinstall the jack rear access cover. Refer to Section 7.1.
7.5 Air Line Filter/Regulator (See Figure 13)
Every 30 hours of operation:
1. Remove the jack rear access cover. Refer to Section 7.1.
2. Completely relieve any trapped pressure in the jack hydraulic
and pneumatic systems. Disconnect the air supply hose
from the air shut-off valve. Follow procedure in Section 7.2.
3. Check the fi lter bowl sight gauge for water. A manual drain is
located at the bottom of the fi lter/regulator bowl. If water is
present, drain it into a suitable container and dispose of it in
accordance with all applicable laws and regulations. Be sure
the drain is fully closed after draining is completed.
