5. Tighten the relief valve locknut when the pressure gauge
reading is stable and is at the desired pressure, then release
the trigger switch.
6. Recheck the final pressure setting by holding the trigger
switch and pressurizing the system.
7. If the final pressure setting is not at the desired setting, then
repeat the procedure described in steps 2 through 6.
13.2 Torquing - Manual Mode Using Trigger Switch
NOTICE
• Pressure will increase until the relief pressure setting is reached.
• If relief pressure is achieved before the torque wrench fully
advances, then desired torque has been achieved.
• If pendant remains connected, blinking green LED will be visible
(same as manual mode operation with pendant). However, red
and yellow LED's will NOT be visible.
1. Place torque wrench on nut or bolt.
2. Press and hold the trigger switch to begin an advance cycle.
Pump will continue to build pressure until pressure in Section
13.1, step 6 is reached.
3. Release trigger switch to start a retract cycle.
4. Repeat steps 2 and 3 until target torque is achieved.
5. The pump will shut-off and relieve all remaining system
pressure if no additional inputs from the trigger switch (or
pendant - if connected) are received within the applicable
time period after full retract. Refer to the following notice
statement for additional information.
NOTICE
• If relief valve pressure is set > 2000 psi [138 bar], the pump will
automatically shut-off 1 second after full retract.
• If relief valve pressure is set < 2000 psi [138 bar], the pump will
automatically shut-off 20 seconds after full retract.
14.0 MAINTENANCE
14.1 Checking Oil Level
1. Be sure torque wrench is fully retracted and that pump is off.
2. Verify that the pressure gauge indicates zero (0) psi/bar.
Be certain that all hydraulic pressure is fully relieved before
continuing this procedure. If any pressure remains, relieve
pressure as described in Section 8.3.
3. Remove the battery from the pump. Refer to Section 7.2.
4. Place the pump on a level surface.
5. Remove the oil fill plug and O-ring from the fill opening. Use
a 7/8" Allen wrench. Be sure that the O-ring is removed with
the oil fill plug. See Figure 10.
6. Visually check the oil level. Reservoir is FULL when oil level
is at the top of the oil fill tube.
• If oil level is OK (reservoir full), then proceed to Step 7.
• If oil level is low, then add oil as described in Section 14.3.
Refer to Section 14.2 for oil requirements.
7. Reinstall O-ring and oil fill plug. Oil fill plug is must be installed
so that top of oil fill plug is recessed below the flange around
the fill opening. Torque to 40-50 in-lbs [4.5-5.7 Nm].
14.2 Hydraulic Oil Information
Use only Enerpac HF hydraulic oil when adding additional oil
or when performing an oil change. Enerpac HF hydraulic oil is
available from Enerpac distributors and Enerpac authorized
service centers.

14.3 Adding Oil
CAUTION
Be certain that the torque wrench is fully
retracted before adding any oil to the reservoir. If an oil-
filled torque wrench is retracted after additional oil has been
added to the reservoir, the reservoir could become overfilled
and burst. Minor or moderate personal injury and/or property
damage could occur.
NOTICE
• Use only Enerpac HF hydraulic oil. Refer to Section 14.2.
• To avoid spillage and to allow proper venting, always use a
funnel of the proper size when adding oil. Spillage will occur if
a funnel is not used.
• Use only new oil poured from a clean container.
• Always remove the battery from the pump before adding oil.
This will prevent accidental pump start-up and will also prevent
any spilled oil from contacting the battery during filling.
• Pour oil slowly to avoid spillage. If oil begins to flow from the
concentric vent openings around the oil fill opening, stop
pouring immediately to avoid spillage.
• Remove and dispose of any spilled oil in accordance with all
applicable laws and regulations.
Add oil as described in the following steps:
1. Be sure torque wrench is fully retracted and that pump is off.
2. Verify that the pressure gauge indicates zero (0) psi/bar.
Be certain that all hydraulic pressure is fully relieved before
continuing this procedure. If any pressure remains, relieve
pressure as described in Section 8.3.
3. Remove the battery from the pump. Refer to Section 7.2.
4. Remove the oil fill plug and O-ring from the fill opening. Use
a 7/8" Allen wrench. Be sure that the O-ring is removed with
the plug.
5. Place a funnel (maximum 1/2" [12 mm] stem diameter)
through the fill opening and into the oil fill tube. Be sure 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.
