- Due to our continuing programme of research and development, the specifications herein are subject to change without notice.
- Specifications may differ from country to country.
- Weight according to EPTA-Procedure 01/2003
The tool is intended for cutting sheet steel and stainless sheet steel.
The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. They are double-insulated and can, therefore, also be used from sockets without earth wire.
Noise
The typical A-weighted noise level determined according to EN60745:
- Sound pressure level (LpA) : 83 dB(A)
- Sound power level (LWA) : 94 dB(A)
- Uncertainty (K) : 3 dB(A)
Wear ear protection
Vibration
The vibration total value (tri-axial vector sum) determined according to EN60745:
- Work mode : cutting sheet metal
- Vibration emission (ah) : 7.0 m/s2
- Uncertainty (K) : 1.5 m/s2
- The declared vibration emission value has been measured in accordance with the standard test method and may be used for comparing one tool with another.
- The declared vibration emission value may also be used in a preliminary assessment of exposure.
WARNING:
- The vibration emission during actual use of the power tool can differ from the declared emission value depending on the ways in which the tool is used.
- Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking accoun of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).

The die position can be changed 360°. To change it, proceed as follows.
- Loosen the lock nut with the wrench provided.
- Pull the die holder slightly and turn it to the desired position for operation.
- Tighten the lock nut to secure the die holder in the desired position.
There are four positive stops at 90° each: 0°, 90° left and right and 180°. To position the die to any of these positive stops:
- Loosen the lock nut with the wrench provided.
- Pull the die holder slightly and depress lightly while turning it to the desired position. The die holder will lock into one of the positive stop positions as desired.
- Turn the die holder slightly to make sure that it is positively locked into position.
- Tighten the lock nut to secure the die holder.
Permissible cutting thickness
The notch in the die holder indicates your cutting line. Its width is equal to the cutting width. Align the notch to the cutting line on the workpiece when cutting.
CAUTION:
- Before plugging in the tool, always check to see that the switch actuates properly and returns to the “OFF” position when the rear of the switch lever is depressed.
To switch on, depress the rear of the switch lever and push it forward. Then depress the front of the switch lever to lock it.
To switch off, depress the rear of the switch lever.
ASSEMBLY
CAUTION:
- Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
OPERATION
Hold the tool so that the cutting head is at a right angle (90°) to the workpiece being cut. Move the tool gently in the cutting direction.
Cutouts
Fig.9
Cutouts can be done by first opening a round hole over 21 mm in diameter which the cutting head can be inserted into.
Cutting the corrugated or trapezoidal sheet metals
Fig.10
Set the die position so that the die faces the cutting direction either when cutting at an angle or perpendicular go grooves in corrugated or trapezoidal sheet metals. Always hold the tool body parallel to the grooves with the cutting head at a right angle (90°) to the cutting surface as shown in the figure.
Fig.11
MAINTENANCE
CAUTION
- Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
