Safety • Inspect the area where the equipment is to be used and remove all objects such as rocks, toys, and wire which can be thrown by the machine. • 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.
• Read all attachment manuals. • 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.
– Keep container nozzle in contact with the tank during filling. • 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. • Carefully release pressure from components with stored energy. • Disconnect the battery or remove the spark plug wires before making any repairs.
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.

Hour Meter/Tachometer to remind you to change the engine oil. After every 100 hours, the screen displays SVC to remind you to perform the other maintenance procedures based on a 100, 200, or 400 hour schedule. These reminders come on starting three hours prior to the service interval time and flash at regular intervals for six hours. When the engine is off, the hour meter/tachometer displays the number of hours of operation that have been logged on the traction unit.
Operation In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Note: Determine the left and right sides of the machine from the normal operating position. Important: Before operating, check the fuel and oil level, and remove debris from the traction unit. Also, ensure that the area is clear of people and debris.
chance of varnish deposits in the fuel system, use fuel stabilizer at all times. Filling the Fuel Tank 1. Park the traction unit on a level surface, lower the loader arms, and stop the engine. 2. Remove the key and allow the engine to cool. 3. Clean around the fuel tank cap and remove it. 4. Add unleaded gasoline to the fuel tank, until the level is just below the bottom of the filler neck. Figure 15 1. Filler cap Important: This space in the tank allows gasoline to expand.
