156 S450 Operation & Maintenance Manual
FUEL SYSTEM
Fuel Specifications
Low sulfur diesel fuel or ultra low sulfur diesel fuel must
be used in this machine. Low sulfur is defined as 500 mg/
kg (500 ppm) sulfur maximum. Ultra low sulfur is defined
as 15 mg/kg (15 ppm) sulfur maximum.
Use only clean, high quality diesel fuel, Grade Number
2-D or Grade Number 1-D.
The following is one suggested blending guideline that
should prevent fuel gelling during cold temperatures:
NOTE: Contact your local fuel supplier to receive
specific recommendations for your region.
NOTE: Biodiesel blend fuel may also be used in this
machine. Biodiesel blend fuel must contain
no more than five percent biodiesel mixed
with low sulfur or ultra low sulfur petroleum
based diesel. This biodiesel blend fuel is
commonly marketed as B5 blended diesel
fuel. B5 blended diesel fuel must meet ASTM
D975 (US Standard) or EN590 (EU Standard)
specifications.
Biodiesel Blend Fuel
Biodiesel blend fuel has unique qualities that should be
considered before using in this machine:
• Cold weather conditions can lead to plugged fuel
system components and hard starting.
• Biodiesel blend fuel is an excellent medium for
microbial growth and contamination that can cause
corrosion and plugging of fuel system components.
• Use of biodiesel blend fuel may result in premature
failure of fuel system components, such as: plugged
fuel filters and deteriorated fuel lines.
• Shorter maintenance intervals may be required, such
as: cleaning the fuel system and replacing fuel filters
and fuel lines.
• Using biodiesel blended fuels containing more than
five percent biodiesel can affect engine life and cause
deterioration of hoses, tubelines, injectors, injector
pump, and seals.
Apply the following guidelines if biodiesel blend fuel is
used:
• Ensure the fuel tank is as full as possible at all times
to prevent moisture from collecting in the fuel tank.
• Ensure that the fuel tank cap is securely tightened.
• Biodiesel blend fuel can damage painted surfaces,
remove all spilled fuel from painted surfaces
immediately.
• Drain all water from the fuel filter daily before
operating the machine.
• Do not exceed engine oil change interval. Extended
oil change intervals can cause engine damage.
• Before machine storage; drain the fuel tank, refill with
100% petroleum diesel fuel, add fuel stabiliser, and
operate the engine for at least 30 minutes.
NOTE: Biodiesel blend fuel does not have long term
stability and should not be stored for more
than 3 months.
