Enerpac ECSE300, Instruction Sheet

16

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.
10.  Using the oil dispenser prepared in step 1, slowly 

add new Enerpac HF oil through the diaphragm 

opening until the diaphragm opening is nearly full.

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.

11.  Connect the cutter to the AC power supply.
12.  Cover the diaphragm opening with a rubber-gloved 

hand to help prevent oil splashing.

13.  Prime the pump by turning the control knob to the 

right (open) 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 jaws start 

to open.

NOTICE

During priming, the oil may become entrained 

with air and may develop a foamy appearance. This is 

normal.
14.  Continue turning the control knob to the right (open) 

in short bursts until the jaws fully open. During this 

process, continue adding oil to keep the reservoir 

full.

15. Slowly install the diaphragm in the diaphragm 

opening. This should result in some oil leakage from 

around the diaphragm.

16.  Install and securely tighten the diaphragm cover.
17. Install the rubber support onto the diaphragm 

cover.

NOTICE:

  WARNING

To avoid serious personal injury, stay clear of cutting 

head and blades during the following procedures.

18.  Start the cutter and cycle the jaws through several 

open and close cycles. Ensure that jaws are fully 

closed when done.

19.  Disconnect the cutter from the AC power supply.
20.  Be sure cutter is positioned so that the oil reservoir 

cap is facing upwards. Do not operate cutter for 

several hours (preferably overnight) to allow any 

remaining air to separate from the oil.

21.  Loosen and remove the oil reservoir cap. Recheck 

the oil level in the oil drain/fill hole. If oil level has 

dropped, add additional Enerpac HF oil until the oil 

level is up to the top of the hole.

22.  Install and securely tighten the oil reservoir cap.
23.  Using a clean rag, wipe the cutter housing, grip and 

motor so that surfaces are free of oil residue.

24.  Connect the cutter to the AC power supply. Cycle 

the piston several times to test for proper operation 

before placing the cutter back into service.

10.6  Greasing the Central Pin

Check that the central pin is lubricated periodically or 

daily if used frequently.
To grease the pin, use a lithium-based water repellent 

grease. Apply several pumps from a hand grease gun 

until grease is evident around the pin. Wipe up any 

excess grease. See Figure 10.
