Danger!

Repairs to power tools must be car-

ried out by qualified electricians only!

Welding machines in need of repair can

be sent to the service centre of your

country. Refer to spare parts list for

address.

Please attach a description of the fault to

the machine.

All packaging material are 100 % recy-

clable.

Worn out power tools and accessories

contain considerable amounts of valua-

ble raw and rubber materials, which can

be recycled.

These instructions are printed on paper

produced with elemental chlorine free

bleaching process.

The machine is safeguarded against

overloads by multiple protection devices,

working independent of each other.

Part of these protection devices are the

fine-wire fuses on the PCBs. If any of

these fuses blows this indicates a seri-

ous machine defect.

B

Danger! High voltage!

Never attempt to replace a fine-wire

fuse inside the machine yourself.

Contact a qualified electrician!

Before replacing a blown fuse the

machine needs a complete check and

any defects repaired!
