NOTICE A small amount of hydraulic oil may leak from
the drain/fill hole when cap is loosened 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.
5. Slowly loosen the oil reservoir cap while watching for
oil flow:
• If oil starts flowing from the oil drain/fill hole as the
cap is loosened, the reservoir is full. Tighten the
cap immediately. To avoid excessive oil spillage, do
not continue loosening the cap if oil flow occurs.
Skip steps 6 through 8 and go on to step 9.
• If no oil flow occurs when the cap is loosened,
fully loosen and remove the cap. Then, check oil
level and add oil (if needed) as described in steps
6 through 8.
6. Check the oil level in the drain/fill hole. Oil level will be
up to the top of the hole when reservoir is full.
7. If oil level is low, loosen the vent screw to provide
venting. Then, slowly add new Enerpac HF oil through
the oil drain/fill hole, until the oil level is up to the top
of the hole.
8. Remove any residue or metal particles from the oil
reservoir cap (it is magnetic).
9. Install and securely tighten the oil reservoir cap.
10. Tighten the vent screw (if loosened).
11. Using a clean rag, wipe the cutter housing, grip and
motor so that these surfaces are free of oil residue.
12. Connect cutter to AC power supply. Cycle the
piston several times to test for proper operation
before placing the cutter back into service.
10.5.1 Hydraulic System Maintenance Precautions
NOTICE: WARNING
Always disconnect cutter from AC power supply
before performing hydraulic system maintenance.
Failure to observe this precaution could result in
accidental start-up while maintenance procedures
are being performed. Serious personal injury and
damage to cutter may result.
Wait for cutter to cool before performing hydraulic
system maintenance. Hot oil can cause burns.
Be sure that oil reservoir cap is securely tightened
after checking oil level or changing the oil. Leaking
oil can cause short circuits, fire and explosions.
Additional Precautions:
• Do not check oil level or change the oil in dusty areas.
• Be sure that all tools (wrench, screwdriver, etc.) used
to perform maintenance procedures are clean.
• When adding oil and performing oil changes, take every
precaution to prevent impurities from contaminating
the oil or entering the cutter. Impurities can cause
permanent damage to the hydraulic components.
• The hydraulic reservoir contains a rubber diaphragm
that slightly pressurizes the oil. Some oil spillage may
occur when checking the oil level or when changing
the oil. Wear and/or use appropriate personal
protective equipment (PPE) to prevent exposure to
hydraulic oil.
• Use only new Enerpac HF hydraulic oil poured from a
clean container. Use of other oil brands and/or used
oil may damage the cutter and may void the Enerpac
product warranty.
10.5.2 Checking Oil Level and Adding Oil
NOTICE
The reservoir contains a flexible rubber
diaphragm that slightly pressurizes the oil. To help
prevent excessive oil leakage when the reservoir cap is
removed, be certain that the piston is fully extended
before loosening the cap.
Refer to Figures 13A through 13D during the following
steps:
1. Operate the cutter and advance the piston until it is
fully extended.
2. Disconnect the cutter from the AC power supply to
prevent accidental motor start-up during the following
steps.
3. Place the cutter in the horizontal position, on a stable
and level work surface, with the oil reservoir cap
facing upwards. Place a pan or suitable container
under the cutter to catch any spilled oil.
4. To prevent contamination, remove any built-up dust
and dirt from the oil reservoir cap and surrounding
area.
