STARTING THE ENGINE (CONT’D)
Figure OI-77
Cold Temperature Starting Procedure 1
IMPORTANT Do not engage the starter for longer than 15 seconds at a time. Longer use can damage the starter by overheating. Allow starter to cool for one minute before using starter again. I-2034-0700 P-32715
If the temperature is below freezing, perform the following to make starting the engine easier: Replace the engine oil with the correct type and viscosity for the anticipated starting temperature. (See Oil Chart on Page PM-18.)
When the light goes out, turn the key to the start position and release the key when the engine starts. The key will return to the run position. When the engine speed increases, move the speed control lever to the low speed position until the engine warms up. Turn the key switch off to stop the engine.
Make sure the battery if fully charged. NOTE: If the battery is discharged (but not frozen) a booster battery can be used to jump start the excavator. (See Using A Booster Battery (Jump Starting) on Page PM-27.)
