Starting the engine
WARNING
Equipment failure could cause accident or injury!
Before operating the machine, check for correct operation of steering, brakes, hydraulic controls,
instruments, and safety equipment. Make sure the transmission control lever is in the neutral position.
Make all adjustments before operating the machine.
Failure to comply could result in death or serious injury.
NOTICE: Running the engine at idle for an extended time ( 6 h maximum) is not recommended. Damage to the SCR
muffler may occur. After an extended idle period, operate the machine under load for a minimum of 30 min .
1. Turn the master disconnect switch to the ON position.
2. Take up the correct position in the operator's seat with the seat belt correctly fastened. Make sure you can push
the foot pedal completely down with your back against the seat cushion.
3. Make sure the parking brake is engaged.
4. Make sure the equipment control levers are in NEUTRAL with the equipment on the ground.
NOTE: The direction control lever must be in NEUTRAL or the engine will not crank.
5. Turn the key switch to the ON position, and check the instrument indicators.
6. Keep all unauthorized personnel clear of the area.
7. Sound the horn to alert others of your intent to start the engine.
8. Turn the key switch to the START position until the engine starts, then release the key.
NOTICE: Do not operate the starter motor more than 30 s at one time. Let the starter motor cool for 3 min before
you engage the starter motor again. While the starter motor is engaged, white or black smoke must be seen at
the exhaust pipe. Check the fuel supply if no smoke is seen.
9. Check the instruments to make sure the indications are correct after the engine starts. Run the engine at low idle
with the transmission in neutral until the engine coolant temperature is warm.
NOTICE: Operate the machine at reduced loads until all systems reach operating temperature. This is very
important during extremely cold weather operation to protect both the engine and hydraulic systems.
Engine speed
DO NOT OPERATE the engine at idle speed for long periods. This can cause a low operating temperature. A low
operating temperature can cause acids and deposits in the engine oil.
Run the engine at low idle for a minute at start up before picking up speed and load.
Always bring the engine to low idle for a few minutes to let all parts cool evenly before shut down.
NOTICE: Always shut the engine down from the lowest idle to prevent damage to the turbocharger.
