11. Position the cutter with the control valve oil holes
pointing straight down, and allow the remaining oil
to drain for 30 to 60 minutes. Toward the end of this
time, the end of the cylinder opposite the oil holes
can be elevated slightly to aid in the draining.
12. Reinstall the directional control valve, using new
O-rings.
NOTICE
Use only new Enerpac HF oil in the following
step. Use of other oils may damage the cutter and may
invalidate the Enerpac product warranty.
13. Using the oil dispenser prepared in step 1, slowly
add new Enerpac HF oil through the oil drain/fill hole
and diaphragm opening until oil level is up to the top
of the drain/fill hole.
14. Install and securely tighten the oil reservoir cap.
NOTICE:
WARNING
To avoid serious personal injury, stay clear of cutting
head and blades during the following procedures.
Wear rubber gloves to prevent contact with oil. Wear
eye and face protection to avoid injury due to
splashing oil.
15. Connect the cutter to the AC power supply.
16. Move the directional lever to position 2 (retract).
17. Cover the diaphragm opening with a rubber-gloved
hand to help prevent oil splashing.
18. Prime the pump by pressing and releasing the
trigger in short bursts. During this process, check
the oil level in the diaphragm opening and add oil
(as needed) to keep the reservoir filled. Failure to
keep reservoir full may result in cavitation and
pump failure. Pump is primed when piston starts
extending.
10.5.3 Changing the Oil
NOTICE The oil change procedure is very detailed and
will take a considerable amount of time. It should only be
performed by a trained technician at an Enerpac
authorized service center. Failure to properly perform the
procedure may result in incomplete filling of the cutter oil
reservoir, which could lead to cavitation, air entrainment,
reduced performance, and pump damage.
Change the oil in the cutter hydraulic reservoir as
described in the following steps. Refer to Figures 10A
through 10E and Figure 11:
1. Before beginning, procure a new seal kit for use on
the control valve.
2. Fill a clean oil dispenser with new Enerpac HF oil. Put
the dispenser aside for later use.
3. Operate the cutter and extend the piston all the way
forward.
4. Disconnect the cutter from the AC power supply to
prevent accidental motor start-up during the following
steps.
5. Place the cutter in the horizontal position, on a stable
and level work surface, with the oil reservoir cap
and diaphragm cover pointing upwards. Place a pan
or suitable container under the cutter to catch any
spilled oil.
6. To prevent contamination, remove any built-up dust
and dirt from the oil reservoir cap, diaphragm cover,
and surrounding area.
NOTICE A small amount of hydraulic oil leakage may
occur when the diaphragm cover and reservoir cap are
removed in the next step. Be prepared to catch this oil in
a pan or with a clean rag. Dispose of spilled oil in
accordance with all applicable laws and regulations.
7. Remove the oil reservoir cap and, using an adjustable
face spanner wrench, loosen and remove the
diaphragm cover.
8. Remove the diaphragm from the diaphragm opening.
9. Completely drain all old oil from the cutter, turning
it upside down and using a suitable oil extraction
system (used oil extraction pump) if necessary, so
that no oil remains in the cutter hydraulic reservoir.
NOTICE
Dispose of all used oil in accordance with all
applicable regulations and laws.
10. After all oil is evacuated, remove the directional
control valve by removing the four screws retaining
it.
