Safety • Use extra care when handling gasoline and other fuels. They are flammable and vapors are explosive. – Use only an approved container – Never remove the gas cap or add fuel with the engine running. Allow the engine to cool before refueling. Do not smoke. – Never refuel or drain the machine indoors. • Check that the operator’s presence controls, safety switches, and shields are attached and functioning properly. Do not operate unless they are functioning properly.
• Ensure that the area is clear of other people before operating the traction unit. Stop the traction unit if anyone enters the area. • Never leave a running traction unit unattended. Always lower the loader arms, stop the engine, set the parking brake, and remove the key before leaving. • Do not exceed the rated operating capacity, as the traction unit may become unstable which may result in loss of control. • Do not carry a load with the arms raised. Always carry loads close to the ground.
– Never fill a container while it is inside a vehicle, trunk, pick-up bed, or any surface other than the ground. • Clean debris from attachments, drives, mufflers, and engine to help prevent fires. Clean up oil or fuel spillage. • Let the engine cool before storing and do not store near flame. • Do not store fuel near flames or drain indoors. • Park the machine on level ground. Never allow untrained personnel to service the machine. • Use jack stands to support components when required.
Stability Data The following tables list the maximum slope recommended for the traction unit in the positions listed in the tables. Slopes over the listed degree may cause the traction unit to become unstable. The data in the tables assume that the loader arms are fully lowered; raised arms may affect the stability. In each attachment manual is a set of three stability ratings, one for each hill position.
