4 - OPERATING INSTRUCTIONS
Cold temperature operation
Cold weather conditions cause special problems. During these conditions, your machine will require special attention
to prevent serious damage. Cold weather maintenance will extend the service life of your machine.
To start and operate your machine during cold ambient temperatures, observe the following recommendation/instruc-
tions.
Battery and electrical components:
• Ensure the batteries are at full charge.
• If you add water to the batteries, charge the batteries or run the engine for approximately two hours to prevent
battery freezing in ambient temperatures below 0 °C ( 32 °F ).
• Inspect the battery cables and terminals. Clean and coat each terminal with a corrosion prevention product.
Engine:
• Use engine oil with the correct viscosity for the ambient temperature range.
• Allow longer warm up periods to bring the machine and components up to operating temperature.
•
WARNING
Explosion hazard!
DO NOT use ether starting fluid. Explosion, death, serious personal injury, or serious engine dam-
age could occur.
Failure to comply could result in death or serious injury.
W0148B
Pre-heat system, engine glow plugs are standard. Turn the key switch to the ON position, the engine pre-heat lamp
illuminates as the heater conditions indrawn air. Wait for the lamp to stop illuminating before starting the engine.
If the engine fails to start after two attempts, allow the battery to recover for 4 to 5 minutes before repeating the
procedure.
•
WARNING
Electrical shock hazard!
NEVER use an ungrounded or inadequate extension cord. Always use a functional (three-wire),
grounded extension cord rated for the appropriate voltage and current (15 A), with circuit protection
of either a standard circuit breaker or a Ground Fault Circuit Interrupter (GFCI).
Failure to comply could result in death or serious injury.
W0400A
If equipped, plug the engine block heater into 110 V outlet for up to four hours before starting the engine. Unplug
the block heater before continuing with the cold weather start procedure.
Fuel system:
• Check with your dealer for the correct cold weather fuel.
• Check for water in the fuel system. Inspect the water separator every 50 hours of operation or when the water in
fuel warning message appears. If water is found, check the fuel tank.
• Fill the fuel tank after each operating day to prevent condensation in the fuel tank and water entering the fuel system.
Cooling system
• Use a mixture of
50 % ethylene glycol and 50 % water. This mixture protects the engine cooling system to -34 °C
( -29 °F ).
Machine start up in cold weather
Machines at temperatures of -15 °C ( 5 °F ) or lower:
• Do not wait longer than 30 seconds after the engine pre-heat lamp has stopped illuminating before cranking the
engine. If the delay is longer, the start up cycle is aborted and the process must be restarted.
