STARTING THE ENGINE (Cont’d)
When an engine is running in an enclosed area,
fresh air must be added to avoid concentration
of exhaust fumes. If the engine is stationary,
vent the exhaust outside. Exhaust fumes
contain odorless, invisible gases which can kill
without warning.
• Engines can have hot parts and hot exhaust
gas. Keep flammable material away.
• Do not use machines in atmosphere
containing explosive gas.

Cold Temperature Starting Procedure
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 FUEL,
COOLANT AND LUBRICANTS, Page 81.)
• Make sure the battery is fully charged.
• Install an engine heater.
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 Page
44.)
Push the speed control lever fully forward [A].
Key Switch (Base Controller)
Turn the key to RUN [B]. If the preheat icon [B] comes ON,
wait for it to go off then turn the key to START [B].
Release the key when the engine starts. It will return to the
RUN position.
Stop the engine if the warning lights and alarm do not go
OFF. Check for the cause before starting the engine again.
When the engine speed increases, move the speed control
lever to idle position until the engine warms.
Keyless Start (Keyless Controller Only)
Follow STARTING PROCEDURE (Keyless Start) Page 19.
If the preheat icon [B] comes ON, wait for it to go off before
pressing the START Button.
The remaining preheat time (in seconds) will count down in
