6. Tool reset

In some rare cases, it may occur that it is not possible to bring the welding unit back to its initial position

Also the rocker lever is blocked.

Important!

Reason for this behavior may be:

Never try to lift the rocker lever with force.

• Interrupt of power supply during welding process (disconnection of battery?!)

• Pulling the rocker lever with force during welding process (to protect the motor, it switches off

due to over-current consumption).

• Microswitch (Pos. 103) is defective  reparation is necessary.

• PCB or wirings are faulty  reparation is necessary.

To debug the 2 possibilities given on top, the tool is equipped with a reset feature, as also stated in

chapter 6.3 in the operating instructions:

1. Switch to fully automatic mode.

2. Press and hold the welding button, thereafter press the tension button.

The tool will now run the welding function and so turn the cam ring away from its inappropriate position.

But probably the motors torque may not be sufficient to do so. Do not try to execute this process more

than 3 times within a short period. Otherwise the motor may get damaged.

If you have not been successful so far, and the rocker lever is still blocked, proceed as follows:

1. Insert an Allen key (3mm) through the hole in front of the base plate and apply on cylinder head

screw. Pos. 164.

2. Turn 10 revolutions counterclockwise. Moderate effort may be needed to do so.

3. Pull rocker lever  welding shoe must swing up.
