10.6  Cutter Blade Replacement

NOTICE:

  WARNING

• Always disconnect cutter from AC power supply 

before beginning blade replacement procedures. 

Failure to observe this precaution could result in 

accidental startup during blade replacement. Serious 

personal injury could result.
• Use extreme caution when removing and installing 

blades. Blades may be sharp even when worn. To 

avoid hand injury, wear appropriate personal 

protective equipment (PPE) and avoid contact with 

blade cutting edges.
10.6.1  Blade Wear

The use of worn blades decreases the effectiveness of 

the cutter and can also side load the cylinder, resulting 

in possible damage to the tool. Motor overheating can 

also occur.
Replace blades immediately if they are worn and/or 

damaged or if there has been a noticeable decrease in 

cutting performance.

NOTICE

Blades are not sharpenable and must be 

replaced when worn. To help ensure optimum cutting 

performance, replace both the fixed blade and the 

moving blade at the same time.

27. Move the piston release lever to position 1 and 

tighten.

28.  Connect the cutter to the AC power supply.

NOTICE:

  WARNING

To avoid serious personal injury, stay 

clear of cutting head and blades during the following 

procedures.

29.  Start the cutter and cycle the piston through several 

advance and return strokes. Ensure that piston is 

fully retracted when done.

NOTICE

Orient the oil reservoir cap facing upwards at 

this time, and keep it as such until the cap is installed for 

the final time.  Failure to do so may result in air remaining 

in the reservoir.  This may require special consideration 

when the soft metal bar is used.  
30.  Do not operate cutter for several hours (preferably 

overnight) to allow any remaining air to separate 

from the oil.

31.  Place the soft metal bar (refer to step 2) into the 

cutting head. 

32.  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 level is being checked. 

NOTICE

If you cut completely through the bar, try again, 

cutting as far as you can without making a full cut.
33.  Disconnect the cutter from the AC power supply 

to prevent accidental motor start-up during the 

following steps.

34. Loosen and remove the oil reservoir cap. Check 

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.

35.  Install and securely tighten the oil reservoir cap.
36.  Move the piston release lever to position 2 to retract 

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

push the piston back until it retracts.

37.  Using a clean rag, wipe the cutter housing, grip and 

motor so that surfaces are free of oil residue.

38.  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.
