12. SAFETY INSTRUCTIONS FOR REPAIRS
The "Safety instructions for repairs" section does not consist of instructions for repair, but instead of safety
instructions which, in addition to the generally applicable safety regulations for repair work, point out hazards that
may arise during repair work, and instructions intended to prevent damage to the wheel loader when carrying out
repairs. Specific instructions for repairs are not included in these operating instructions.
