9.2  Operating Precautions

NOTICE:

  WARNING

Failure to observe the following 

precautions and instructions could result in death or 

serious personal injury.
• Keep fingers, hands and other body parts clear of 

the cutting head. Do not reach into the cutting area 

during cutter operation.
• Do not attempt to reposition the item being cut 

while the cutter is in operation. If repositioning is 

required, stop the cutter and loosen the piston 

release lever to retract the piston. Then, tighten the 

piston release lever and repeat the cutting process.
• Dangerous projectiles could occur at any time 

during cutting. Always wear face and eye protection. 

Keep persons away from cutting area.
• Cutter surfaces can become very hot. To prevent 

burns, avoid contact with cutter components and 

wear appropriate personal protective equipment.
•  Refer to additional safety precautions in Section 1.0 

of this manual before using the cutter or performing 

any maintenance or repair activities.
9.3  Trapped Air Removal

Before placing a new cutter into operation, cycle the 

piston several times without load to remove any trapped 

air in the hydraulic circuit.
Air is completely purged when the piston advances and 

retracts smoothly in both directions, from fully advanced 

to fully retracted.
This procedure should be performed after the oil in the 

cutter is changed, and after any maintenance or repair 

activity in which the oil is drained and replaced.

9.4  Locating and Positioning the Cutter

•  Before inserting material to be cut inside the cutting 

head, be certain that the cutter is placed on a solid 

and stable work surface of sufficient weight rating 

capacity. Refer to Section 2.2 for cutter weight.

•  Position the cutter as needed using the handle/grip 

mounted at the top of the cutter. The handle/grip 

can also be used for transporting the cutter short 

distances.

NOTICE:

  WARNING

Because the cutter components are very 

heavy, there is a risk of cuts, crushing or broken bones. To 

avoid accidents, use care when working with the cutter. 

Serious personal injury may result if the cutter is not 

properly supported and handled in an appropriate way.
9.5  Positioning Material Inside the Cutting Head

Be sure that the piston and moving blade are located in 

the fully retracted “home” position before placing any 

material inside the cutting head. See Figure 4.
Position the material to be cut between the cutter 

blades, so that it is perpendicular to the piston axis, as 

shown in Figure 6. This will provide the best quality cut 

while placing the least amount of load on the cutter. If 

possible, center the material vertically to help reduce 

side-loading of the piston.

Adjust the support bolt as needed. The head of the 

support bolt should just touch the surface of the material 

to be cut, when the item is positioned against the fixed 

blade of the cutter.
After adjusting the support bolt, be sure that the support 

bolt retaining nut is snug tight against the support 

bolt mounting ear. This will help prevent support bolt 

movement during cutting.

NOTICE

Be certain that the maximum parameters of the 

material to be cut are within allowable limits.

 Refer to 

Section 2.1

 of this manual for additional information. 

Failure to observe this instruction may result in poor 

cutting performance and/or damage to the cutter.

9.6  Cutting Procedure (typical)

1. Connect the cutter to the electrical outlet.
2. Be sure that the piston is in the “home” (fully retracted)

position. See Figure 4.

3. Be sure that the piston release lever is turned fully 

clockwise to position 1. See Figure 5.

4. Place the material to be cut between the fixed and 

moving blades. Refer to instructions in Section 9.5 for 

additional information.

NOTICE

Position the item to be cut so that it is as 

perpendicular as possible to the blades, as described in 

Section 9.5. Positioning the material at an angle will 

side-load the piston. Jamming and/or damage to the 

cutter may result.
5. Be certain that hands, fingers or other body parts are 

not inside the cutting head.

6. Press and hold the trigger to start the motor and begin 

cutting.

7. After cutting is completed, wait until the piston 

reaches the end of its stroke and then release the 

trigger. Verify that the moving blade reverses direction 

and moves fully into the “home” (fully retracted) 

position.
