10.5.1 Hydraulic System Maintenance Precautions
NOTICE:
WARNING
Always remove battery from cutter before performing
hydraulic system maintenance. Failure to observe
this precaution could result in accidental startup
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 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 advanced until
there is a gap of about 1/8 inch [3-4 mm] between the
fixed and moving blades (as described in step 1) before
loosening the cap.
The gap between the blades should not be less than
1/8 inch [3-4 mm]. A smaller gap may result in the piston
retracting unexpectedly while the oil level is being
checked.
Refer to Figure 14 and Figures 15A through 15C during
the following steps:
1. Operate the cutter and advance the piston until
there is a 1/8-inch [3-4 mm] gap between the fixed
and moving blades (until just before the piston
automatically returns).
2. Remove the battery to prevent accidental motor
startup during the following steps.
3. Place the cutter on a stable and level work surface,
with the oil reservoir cap facing straight up. Note that
the cap does not face straight up when the tool is
laid on a flat surface, so positioning aids are required.
Place a pan or suitable container under the cutter to
catch any spilled oil.
NOTICE
The oil reservoir cap is located just below the
on-off trigger when the cutter is positioned in the
inverted (upside-down) position. Be certain to remove
only this cap in the next step. DO NOT remove the relief
valve by mistake. See Figure 14.

Key:
1. Oil Reservoir Cap
2. Relief Valve
(DO NOT remove)
4. To prevent contamination, remove any built-up dust
and dirt from the oil reservoir cap and surrounding
area.
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, 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).
