Safety

2.1 Intended use
The tool is intended for the following uses:
Cutting/snipping hard materials up to a hardness of 48 HRC Any use beyond the intended purpose or any unauthorized modification shall be considered improper. The operator shall be liable for damages resulting from improper use. Intended use also includes adhering to these operating instructions. They must be read in full before use.
Warning!
Danger from sharp blades! Handling sharp blades is dangerous. For this reason, make sure to handle your tools with care when working.
Warning!
Wear protective gloves, goggles and a hard hat! Wear protective equipment when cutting/snipping hard materials to avoid the risk of injury from flying parts!

Design and function

3.1 Design

Design bolt cutter

Hardened cutting edges
Replaceable cutter head
Eccentric screws with nuts for precise setting and readjustment
Joint screw
Stop with damping insert
Ergonomically angled handles
Handles with grip sleeves

3.2 Function
The bolt cutter is used to cut/snip hard materials with a diameter of 5 to 13 mm (depending on the hardness and type of material to be cut).

Operation

4.1 Cutting with the bolt cutter
Cutting e.g. structural steel

Insert the material to be cut between the cutting edges of the bolt cutter, as close as possible to the joint.
Firmly press the two handles together.

In normal use with material that is not too soft / too hard, the preset gap between the cutting edges does not have to be changed. However, you can set a smaller gap for very soft material (e.g. copper bars) or a larger gap for very hard material. Note: Materials with a diameter of less than 2 mm cannot be cut.

Maintenance

5.1 Readjusting the cutting edges of the cutter head
The cutting edges of the bolt cutter have a preset gap of approx. 0.4 mm. This gap does not need to be readjusted during normal use. If there is high level of wear, it is possible to readjust the gap.

Loosen the two outer nuts.
Push the eccentric screws up a little.
Adjust the gap by turning the two eccentric screws. You can choose from 12 different positions.
Note: The cutting edges must not be completely closed, otherwise they can break.
Adjusting the cutting edges of the cutter head
Push the eccentric screws back down.
Tighten the nuts again.
Secure the nuts with a gentle tap with a center punch or with screw locking.

5.2 Changing the cutter head
The spare part numbers for the four different sizes can be found in the “Technical data” chapter.

Loosen the three nuts completely.
Remove the three screws.
Pull the old cutter head out of its holder.
Pull the handles apart.
Clean and lightly oil all joints.
Reattach the handles to the joint screw and tighten the nut slightly.
Push the new cutter head into the holder.
Fasten it with the two eccentric screws and nuts.
Secure the nuts with a gentle tap with a center punch or with screw locking.
