1. SAFETY INSTRUCTIONS

GENERAL POWER TOOL SAFETY WARNINGS

•   To operate this device safely, the user must 

have read and understood these instructions for 

use before using the device for the first time.

•    Observe all safety instructions! Failure to do so 

may cause harm to you and others.

•    Retain all instructions for use, and safety 

instructions for future reference.

•    If you sell or pass the device on, you must also 

hand over these operating instructions.

•    The device must only be used when it functions 

properly. If the product or part of the product is 

defective, it must be taken out of operation and 

disposed of correctly.

•    Do not use the tool for work on live parts, it may 

result in electric shock, fire and/or serious injury. 

Make sure the electrical supply is turned off 

before stripping off the casing.

•   Test the circuit for voltage. Always double-

check the wire to make sure it's not carrying 

electricity. Get a multimeter, turn it to the 

voltage setting, and hook it up to the wire. 

If the readout doesn't stay at zero volts, the 

circuit is still getting power. Shut off the power 

completely before trying to strip it.

2. MACHINE INFORMATION

Intended use

The automatic stripping tool allows the stripping 

and cutting of solid and stranded wires/cables. 

The jaws automatically adjust to the size of the 

cable, allowing the end of the insulator to be easily 

removed, revealing the conductor. The tool can 

also be used for crimping and pressing common 

insulated and non-insulated terminals. The tool is 

not suited for work on live parts.

3. OPERATION

Stripping wire (Fig. A, B)

Insert the wire as shown on figure B1 or figure B2. 

Now squeeze the plier to remove the insulation 

from the wire.

End stop (Fig. A, B)

To strip multiple wires on the same length, the 

end stop (3) can be used (figure B1). First turn the 

end stop (3) upwards. Adjust the end stop to the 

desired length and afterwards fixate it by turning it 

downwards again.

 Do not engage the end stop when stripping 

wires in a position as shown on figure B3.

Adjusting the tension (Fig. A)

The tension of the jaws can be adjusted by turning 

the tension adjustment knob (1). Turn clockwise 

to tighten, turn anti-clockwise to loosen. If the 

insulation on the wire is damaged after stripping, 

the tension is too high. If the plier is unable to strip 

the insulation of the wire, the tension is too low. 

The right setting can be determined by practical 

testing, depending on the wire type and diameter.

Cutting wire (Fig. A)

Use the sharper shaped part marked as cutter (7) 

to cut wire.

Crimping insulated wire (Fig. C)

The plier offers crimping capabilities of common 

insulated terminals, as shown on figure C. Use only 

the colour-coded crimping insulated terminal (4) 

part of the plier.
