PREVENTIVE MAINTENANCE
• 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
causing 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, lintfree
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
ENGINE MAINTENANCE
Specification: Use only Diesel Fuel, Grade 2-D, as recommended
by engine manufacturers. If you need further
information on Grade 2-D fuel specifications, consult the
Engine Operation Manual in the glove compartment.
WARNING! Diesel fuel in the presence of an
ignition 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. Otherwise,
the pump and engine will be damaged.
Don't try to dilute the gasoline by adding diesel
fuel (see Warning above).
CAUTION: Use Ultra Low Sulfur Diesel fuel
only. Failure to do so may damage components
of the engine and Diesel Particulate Filter
(DPF).
