The specified intervals are standard values and refer to single-shift operation. We recommend recording the
inspections. The date of the inspection, the detected defects and the name of the inspector must be observed.

Fatal electric shocks can occur if components are live during maintenance and cleaning work.
► Set the main switch for the power source to <0> before maintenance and cleaning work.
► Disconnect the electrical mains connection from the power source.

Electric shock due to defective cables
The use of damaged or improperly installed cables may result in a potentially fatal electric shock.
► Check all live cables and connections for proper installation and damage.
► Have any damaged, deformed, or worn parts replaced by a qualified electrician only.

Material damage due to improper disassembly of the wire feeder motor
The wire feeder motor is mounted in such a way that no dust can penetrate it. If the wire feeder motor is
disassembled, the encoder may become damaged, which could cause the wire feeder motor to
malfunction.
► Do not disassemble the wire feeder motor.
► A defective wire feed motor should be replaced by a qualified electrician.
