Roading the Machine
`

------ WARNING! ------

The steering circuit temperature monitoring system, if equipped, will alert you when reduced steering performance is detected due to cold temperatures. Failure to respond to this warning could result in injury or death. Ensure that the hydraulic oil type installed in the machine is matched to the hydraulic oil type setting in Messenger.


Before you road a machine, consult your tire dealer for recommended tire pressures and for speed limitations.

Limitations for TON-kilometer per hour (TON-mile per hour) must be obeyed. Consult your tire dealer for the speed limit of the tires that are used.

When you travel for long distances, schedule stops in order to allow the tires and the components to cool. Stop for 30 minutes after every 40 km (25 miles) or after every hour. Consult your local tire dealer for machines that are equipped with "L4/L5" tires.

Inflate the tires to the correct pressure.

Use a self-attaching inflation chuck and stand behind the tire tread during the tire inflation. See the Operation and Maintenance Manual, "Tire Inflation Information" section for more information.

Perform a walk-around inspection to ensure the machine is in safe operating condition.

Check with the proper officials in order to obtain the required licenses and authorization.

If your machine is equipped with the fold down tail lights fold down the tail lights before roading.

Travel at a moderate speed. Observe all speed limitations when you road the machine.

Place the implement lockout switch in the LOCK position to prevent unintended implement movements.

Do not operate the machine with the doors open under high speed applications.

Machine operation in cold ambient conditions may cause the steering system oil temperature to fall below the tank temperature. This can cause a reduction in steering performance. When you operate the machine for an extended period of straight roading these conditions may occur.

Reduce engine speed when you maneuver in tight quarters or when you are going over a hill.

Do not operate the machine close to a cliff. Do not operate the machine near an excavation. Do not operate the machine near an overhang.

When you operate the machine downhill, use two transmission gears less than the transmission gear that is used when you operate the machine up the same hill.

Note: AVSpare does not recommend that you shift to the NEUTRAL position when operating the machine downhill. If you shift to the NEUTRAL position, the machine may require additional braking effort that could accelerate wear of the service brake components.

Do not allow the engine to overspeed when operating the machine downhill. If overspeed exists, use the service brake control to decrease the speed to a level that will allow you to downshift. Repeat this process until a stable or controlled speed is obtained. Before the engine is pushed beyond a dangerous speed level, the transmission will automatically upshift in order to keep the engine speed within a safe speed range. However, when the maximum gear is reached, the service brakes must be used to control the machine speed and the service brakes must also be used to prevent the engine from overspeeding.

Note: For more information on warning categories refer to Operation and Maintenance Manual, "Engine and Machine Warm-Up".
