Types of Fuel to Use
Fuel represents the major portion of the crane’s operating
costs. Therefore, it is important to use it efficiently. Don’t let
cost tempt you to use an inferior diesel fuel. The savings is a
false economy when you consider the damage poor fuel can
do to your crane’s engine.
NOTE: Use only diesel fuel designed for diesel engines.
Some heating fuels contain harmful chemicals
which can seriously affect engine efficiency and
performance.
NOTE: Due to precise tolerances of diesel fuel injection
systems, it is extremely important that the fuel be
kept clean and free of dirt and water. Dirt or water in
the system can cause severe damage to both the
injection pump and the injection nozzles.
Use either a Grade No. 1D or a Grade No. 2 ultra
low sulfur diesel fuel as defined by ASTM
Designation D-975 for diesel engines. In European
countries, use ISO 1585 commercial diesel fuel.
Find the expected air temperature at time of start
up on the thermostatic scale in Figure 6-2. Correct
diesel fuel grade (A, B) is shown next to the scale.
NOTE: If engine is operating at temperatures -40° to -57°C
(0-40° to -70°F), Grade DF-A arctic fuel is
recommended. Also consult the engine distributor
for special lubricants and starting aids.
Cetane number should be a minimum of 40 to
assure satisfactory starting and overall
performance. At low temperatures and/or high
altitudes, minimum cetane number of 45 is
recommended.
NOTE: Excessive white smoke at start up could be a result
of low cetane fuel.
Use Ultra Low Sulfur Diesel (ULSD), with a
maximum sulfur content of 15 ppm in the United
States and 10 ppm in the European Union, with a
cloud point of at least 6°C (10°F) below the lowest
expected air temperature at time of starting. The
cloud point is temperature at which wax crystals
begin to form in diesel fuel.
ENGINE AIR INTAKE SYSTEM
Air for combustion is pulled through an air filter by the
engine. Dust and foreign materials are removed from the air
by the air filter.
WARNING
DO NOT mix gasoline or alcohol with diesel fuel. This
mixture can cause an explosion.
