Before you operate the machine, check monitoring system (4). Take action on any events that are displayed.Note: To provide maximum sound suppression, keep all doors closed and keep all windows closed.
Check the oil levels of the following compartments: engine, hoist/brake hydraulic tank, differential/final drives, steering hydraulic tank and torque converter sump. Refer to the Maintenance Section for information on checking the oil levels.
Check the horn. Check the backup alarm. Check any other warning devices on the machine.
Check the operation of the steering and the brakes. Check the secondary brakes and check the secondary steering. Do not operate the machine if any discrepancies are found. Refer to Operation and Maintenance Manual, "Braking System - Test". Also refer to Operation and Maintenance Manual, "Secondary Steering - Test".
Frequently observe all messages, indicators, and gauges (3). All gauges should be at normal operating range. The system indicators, the action light, and the action alarm should be off.
Adjust the operator's seat. Adjust the mirrors.
Do not allow a companion to ride on the machine unless the companion is seated within the Rollover Protective Structure (ROPS) or Falling Object Protection Structure (FOPS) with the seat belt fastened. The companion must have the seat belt fastened while the machine is in operation. The operator of the machine is responsible for the safety of the companion. Personal injury or death may occur if the companion is not restrained and protected.
Fasten the seat belt.

Before the machine operates at a high speed, check the operation of the brake system and of the steering system. These systems should be checked while the machine maintains a low speed.
Make sure that the Automatic Retarder Control (ARC) operates properly before you travel down a grade with a machine that is loaded. Test the ARC on a short grade before the machine is loaded.
Reduce engine speed when you are maneuvering in tight quarters or when you are driving over a rise.Reference: For further operating information, See Operation and Maintenance Manual, "Operation Information".Low Coolant Temperature Warm-Up
The low temperature warm-up feature will utilize one of two methods to raise coolant temperature. Torque Converter Stall or Elevated Idle. Torque converter stall will take precedence if required conditions are in place. Engine temperatures below normal operating temperature range can decrease the engine life.Torque Converter Stall (Autostall)
The torque convertor will automatically stall to decrease the amount of time for the machine to warm up. The stalled torque converter warms
