SERVICE AND REPAIR PRECAUTIONS:
ALWAYS inspect all slings, chains, or cables when lifting components. Be sure that they are properly tied,
fastened and balanced before lifting. Be sure that the lifting device is capable of retaining the
weight to be lifted.
NEVER attempt to lift heavy parts by hand when a lifting device should be used.
ALWAYS wear safety glasses when performing any maintenance or repair work on the machine.
NEVER attempt to remove or repair any component on the machine while the engine is running.
NEVER leave the machine and/or heavy parts in an unstable position during repair.
ALWAYS support the machine with sound blocking.
ALWAYS keep the machine and work area clear of lubricants and dirt.
ALWAYS use the correct tools for the repair procedures being done on the machine.
ALWAYS keep tools in a good and clean condition.
ALWAYS use approved parts that are designed for the machine being repaired. This helps to ensure
maximum service life of the machine.
ALWAYS be sure that all necessary nuts, bolts, snap rings, and other fastening devices are removed before
using force to remove components.
ALWAYS attach a sign in the machine operator’s area, stating “DO NOT OPERATE” when the machine is
being repaired.
ALWAYS observe ALL WARNING AND CAUTION statements given in the Operating Manual and Service
Manual and found on the machine decals.

General:• For repair work stand the machine on level and firm ground an shut down.• Secure the machine against unintentional rolling.• Secure the engine .reliably against unintentional starting.• Always mark a defective machine by attaching a respective note to the steering wheel.• During work secure the articulated joint with the articulation lock.• Use your protective outfit, such as hard hat and protective boots.• Keep unauthorized persons away from the machine while the repair work is going on.• Tools, lifting gear, lifting tackle, trestles and other auxiliary equipment must be fully functional and in safe condition.• Use only safe and approved lifting gear of sufficient load bearing capacity to removal and install parts or components from and to the machine.• Be careful with cleansing agents. Gasoline or other easily inflammable substances must not be used for cleaning purposes.• Cleaning and repair work on the fuel tank is dangerous. When repairing or cleaning the fuel tank do not smoke in the immediate vicinity, avoid ignition sparks and do not use open fire.• Always observe the welding instructions when performing welding work.
