Oil Draining:
• Refer to the engine manufacturer's Engine Operation
and Maintenance Manual supplied with your vehicle for
information about draining and refilling engine oil, engine
crankcase capacity, engine oil type, and changing oil fil-
ters, etc.
WARNING! Hot engine oil can be dangerous. You
could be seriously burned. Let the engine oil
cool down before changing it.
• Drain the oil into a container designed for this purpose.
• When draining the oil, remove the plug with the proper
size wrench and keep as far away as possible. Always
keep your forearm parallel to the ground to help prevent
hot oil from running down your arm.
• The oil filler cap must be secured to avoid oil spill caus-
ing a potential fire hazard.
Oil Level Check
• To check the engine oil level, park the vehicle on level
ground and wait 5 minutes after shutting the engine OFF.
This allows time for the oil to drain to the oil pan.
• Remove the dipstick and wipe it off with a clean, lint-free
rag.
• Reinsert the dipstick all the way in and pull it out again to
check oil level. Correct oil level is between the low (L)
and high (H) marks on the dipstick.
For further information regarding oil level, see the engine
manufacturer's Engine Operation and Maintenance Manual
supplied with the vehicle.
Fuel System
Specification: Use only Diesel Fuel, Grade 2-D, as recom-
mended by engine manufacturers. If you need further infor-
mation on Grade 2-D fuel specifications, consult the Engine
Operation Manual in the glove compartment.
WARNING! Diesel fuel in the presence of an igni-
tion source (such as a cigarette) could cause an
explosion. You could be killed or seriously
injured. A mixture of gasoline or alcohol with
diesel fuel increases this risk of explosion.
CAUTION: If anyone ever pours gasoline into
your fuel tank, drain the entire system. Other-
wise, the pump and engine will be damaged.
Don't try to dilute the gasoline by adding diesel
fuel (see Warning above).
