Move both the transmission direction control lever and the direction control switch (if equipped) into NEUTRAL.
Lift the steering column release lever and move the steering column to the desired position. Release the steering column release lever in order to lock the steering column into position.
Engage the parking brake.
Move the control levers to the HOLD position.
Before the engine is started, check for the presence of bystanders or maintenance personnel. Ensure that all personnel are clear of the machine. Briefly sound the forward horn before you start the engine.
Turn the engine start switch to the ON position. Pause for three seconds so that the secondary steering (if equipped) can test.Note: In applications for cold weather, pause until the indicator lamp for the starting aid turns off.
Do not push down on the throttle pedal. Turn the engine start switch key in order to engage the starter. Release the key when the engine starts.
Do not crank the engine for more than 30 seconds. Allow the starter to cool for two minutes before cranking again.Turbocharger damage can result, if the engine is not kept low until the engine oil light/gauge verifies the oil pressure is sufficient.
Warm up the Engine and Machine
Keep engine speed low until the engine oil pressure indicator light goes out. If the engine oil pressure indicator light does not go out within ten seconds, stop the engine. Investigate the cause of the problem before you start the engine again.Note: The hydraulic lockout must be in the Unlocked position before the hydraulic controls will function.
Allow the engine to warm up at low idle for at least five minutes. Engage the work tool controls and disengage the work tool controls. This will speed up the warm-up of the hydraulic components.
Look at the indicators and the gauges frequently during operation.Also, to help the hydraulic oil to warm up faster, hold the bucket control in the CLOSE 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 up more rapidly.
The hydraulic control valve may become overheated if the bucket is operated continuously under relief conditions.
Cycle all controls in order to allow warm hydraulic oil to circulate through all hydraulic cylinders and through all hydraulic lines.When you idle the machine for warm-up, heed the following recommendations:
If the temperature is greater than 0° C (32° F), warm up the engine for approximately 15 minutes.
If the temperature
