• Perform only the maintenance described in this
Operator’s Manual.
• All work that is not described in this Operator’s Manual
must be performed by qualified and authorized
technical personnel.
• Follow the maintenance plan – see “Maintenance

overhead maintenance. Do not use vehicle parts or
attachments as a climbing aid.
• Do not use attachments/work equipment as a lift
platform for persons.

Modifications and spare parts
• Do not modify the machine and the work equipment/

tires, straightening and welding work).
• Modifications must be approved by the manufacturer
and performed by an authorized service center.
• Use only original spare parts.
Protective structures
• The cabin, rollbar and protective screen are tested
protective structures and may not be modified (for
example no drilling, bending, welding).
• Perform a visual check according to the maintenance
plan (for example, check the fastenings for damage).
• If damage or defects are detected, have them immedi-
ately checked and repaired by an authorized service
center.
• Have retrofitting work only performed by an authorized
service center.
• Replace self-locking fasteners (for example, self-
locking nuts) by new ones after removing them.
