Cold Weather Engine Starting
Start the engine with the following procedures in cold temperatures:
•
Check the fluid levels before starting the engine. Drain the water and sediment from the fuel/water separator
once a week. See “Check and Drain the Fuel/Water Separator” on page 4-9.
•
Turn the key switch to the HEAT position and release. The key switch returns to OFF. The preheat cycle begins
if the air temperature is less than 37°F (3°C). When the preheat cycle begins, a preheat icon is illuminated on
the home screen. When the preheat cycle is complete, the preheat icon will turn off.
•
Turn the key switch to START, the starter motor will crank the engine. Release the key after the engine has
started and the key switch will return to ON.
•
After the engine starts, check the monitor display for faults or errors.
•
Allow the engine to idle until the engine coolant temperature reaches 140°F (60°C) and the hydraulic oil to
reach a temperatures above 104°F (40°C) before using the machine. Operate all the functions with no load for
5 to 10 minutes.
NOTE:
If the engine fails to start after preheating, wait at least 5 seconds before repeating the process.
WARNING!
•
Before starting the engine or leaving the operator seat, make sure the hydraulic lockout
control lever is in the locked (closed) position. If the hydraulic system is not locked,
unintentional machine operation may occur.
•
Confirm that the surrounding area is clear of personnel and obstructions, and sound the
horn before starting the engine.
•
Always start the engine from the operator seat. Never start the engine by shorting the
starter solenoid or starter relay.
•
Never use ether starting fluid to start the engine. Ether is highly flammable and can cause
a fire or an explosion.
•
Exhaust gas contains carbon monoxide. Carbon monoxide is an invisible and odorless
gas, and is toxic. Provide adequate ventilation when starting the engine in a confined
space.
Failure to follow these warnings could result in death or serious injury.
NOTICE!
Never crank the engine for more than 15 seconds as it could cause damage to the machine or
cause the machine to operate improperly. If the engine fails to start after 15 seconds, stop and
allow the starter motor to cool for at least 2 minutes before attempting another start.
