Keep engine speed low until the engine oil pressure alert indicator goes out. If the alert indicator does not go out within ten seconds, stop the engine and investigate the cause before starting again. Failure to do so can cause engine damage.
Allow a cold engine to warm up at low idle for at least five minutes. To help the hydraulic components to warm up faster, engage and disengage the hydraulic controls to help speed warm up of the hydraulic oil and components.The hydraulic oil will warm up faster if the joystick control is held in the full TILT BACK position for short periods of ten seconds or less. This will allow the hydraulic oil to reach relief pressure, which causes the hydraulic oil to warm more rapidly.Cycle all hydraulic controls in order to allow warm hydraulic oil to circulate through all hydraulic cylinders and through all hydraulic lines.
Look at the alert indicators and the gauges frequently during operation.When you idle the engine in order to warm up the engine, observe the following recommendations:
Allow the engine to warm up for approximately 15 minutes when the temperature is higher than 0 °C (32 °F).
Allow the engine to warm up for approximately 30 minutes or more when the temperature is below 0 °C (32 °F).
More time may be required if the temperature is less than −18 °C (0 °F). More time may also be required if the hydraulic functions are sluggish.Preparing to Operate the Machine
Do not attempt to move the machine without normal brake oil pressure.
In order to prevent injury, make sure that no one is working on the machine or near the machine. Keep the machine under control at all times in order to prevent injury.
Know the maximum height of the machine. Know the maximum width of the machine. Maintain proper clearance.
With the engine at low idle and with the oil at normal operating temperature, check the oil level of the transmission.ReferenceRefer to the Operation and Maintenance Manual, "Transmission Oil Level - Check" for the machine that is being serviced.
Before the machine operates at a high speed, check the operation of the braking system and of the steering system. These systems should be checked while the machine maintains a low speed.Note: Every 10 service hours or daily, test the operation of the braking system. For the correct procedure, refer to the Operation and Maintenance Manual, "Braking System - Test" for the machine that is being serviced.Note: Every 10 service hours or daily, test the operation of the implement and steering lockout systems. For the correct procedure, refer to the Operation and Maintenance Manual, "Steering Lockout (STIC Steering) - Test, or Implement and Steering Lockout (STIC Steering) - Test" for the machine that is being serviced.ReferenceFor further operating information, refer to the Operation and Maintenance Manual, "Operating Technique Information, Loading, Hauling and Dumping, and Bucket Loading Hauling Units" for the machine that is being serviced.
