(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.

 

NOTICE

During priming, the oil may become entrained 

with air and may develop a foamy appearance. This is 

normal.

17.  Continue pressing and releasing the trigger in short 

bursts as the piston extends. During this process, 

do not add oil, but verify that the pump has ample 

oil supply. Continue until piston is extended to 

approximately half stroke.

 

NOTICE

During the following steps, refer to Figure 9 for 

piston release screw details.

18. While covering the diaphragm opening with a 

rubber-gloved hand, retract the piston gently by 

slowly loosening the piston release screw.

19.  Tighten the piston release screw.
20.  Place the soft metal bar (refer to step 2) into the 

cutting head. 

21.  Press and release the trigger in short bursts until 

the piston is extended as far as possible, but before 

it makes a full cut and retracts. The moving blade 

will become lodged in the bar, preventing the 

piston from retracting. This procedure is necessary 

because the cutter mechanism alone may fail to 

hold the piston in the partially extended position as 

oil is being added in the following steps. 

 

NOTICE

If you cut completely through the bar, try again, 

cutting as far as you can without making a full cut.

22. Remove the battery to prevent accidental motor 

startup during the following steps.

23. Add oil through the diaphragm opening until the 

diaphragm opening is nearly full.

24. Slowly install the diaphragm in the diaphragm 

opening. This should result in some oil leakage from 

around the diaphragm.

25.  Install and securely tighten the diaphragm cover.
26. Loosen the piston release screw to retract the 

piston. If piston is stuck, use the bar to manually 

push the piston back until it retracts.

27.  Remove the soft metal bar from the cutting head. 

Do not discard the bar. It will be used again later in 

this procedure.

28.  Tighten the piston release screw.
29.  Insert the battery.

 

NOTICE:

  WARNING

To avoid serious personal injury, stay 

clear of cutting head and blades during the following 

procedures.

30.  Start the cutter and cycle the piston through several 

advance and return strokes. Ensure that piston is 

fully retracted when done.

 

NOTICE

The bar selected should be easy to cut, but not 

brittle. The bar material must be soft enough so that the 

bar will not break into two pieces before it is fully cut. 

Later in this procedure, the bar will be partially cut so 

that it becomes lodged in between the jaws of the cutter 

without being cut through completely, as the piston is 

extended to slightly less than maximum travel. 

3. Ensure the piston is completely retracted.
4. Remove the battery to prevent accidental motor 

startup during the following steps.

5. Place the cutter in the horizontal position, on a stable 

and level work surface, with the oil reservoir cap 

facing up. It is not critical that it face straight up, as 

in the oil check procedure. 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 is 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. Loosen and remove the oil reservoir cap.
8. Using an adjustable face spanner wrench, loosen and 

remove the diaphragm cover.

9. Remove the diaphragm from the diaphragm opening. 
10.  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 reservoir. 

 

NOTICE

Dispose of all used oil in accordance with all 

applicable regulations and laws. 

11.  After all oil is evacuated, position the cutter with the 

diaphragm opening facing up.

12.  Install the oil reservoir cap.

 

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 diaphragm 

opening until oil level is up near the top. 

 

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.

14.  Insert the battery.
15.  Cover the diaphragm opening with a rubber-gloved 

hand to help prevent oil splashing.

16. 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
