TROUBLESHOOTING

The troubleshooting section includes only malfunctions and incorrect operations which must be remedied by
the operator. Any other malfunctions may only be eliminated by trained personnel. The troubleshooting must be

MALFUNCTION column for the corresponding excavator malfunction. In the POSSIBLE CAUSE column you
will find the possible causes for the malfunction. The REPAIR column indicates the required remedial measure.
If the fault can not be remedied by the measure indicated in the REPAIR column, consult trained personnel.
