7 - MAINTENANCE
• Wear and corrosion of internal components due to wa-
ter content, which affects lubricity.
• Deterioration of some rubber sealing compounds in the
fuel system.
• Biodiesel oxidation, which can lead to the formation of
deposits that can harm the fuel injection system.
NOTICE: any problem in the engine fuel injection equip-
ment associated with non-compliance to the following
conditions for biodiesel fuel handling and maintenance
will not be covered for Warranty by CASE CONSTRUC-
TION.
Purchase biodiesel fuel from a trusted supplier who
understands the product and maintains acceptable fuel
quality. The National Biodiesel Board awards
BQ-9000®
accreditation to biodiesel marketers and producers that
meet strict quality and consistency standards. Biodiesel
users in North America are strongly encouraged to pur-
chase biodiesel blends from the
BQ-9000® Certified
Marketers and sourced from the BQ-9000® Accredited
Producers found on the BQ-9000® website.
The use of biodiesel blends up to B5 will not void
the CASE CONSTRUCTION warranty as long as the
following conditions for biodiesel fuel handling and main-
tenance are stringently followed:
Biodiesel fuel must be pre-blended by the supplier. Mixing
biodiesel fuels on-site can result in an incorrect mixture
that could damage the engine and/or fuel system.
NOTICE: CASE CONSTRUCTION may void your war-
ranty if the problem is associated with poor fuel quality
due to improper blending. It is the responsibility of the
fuel supplier and/or yourself to ensure the right type of
fuel and blend is delivered and used.
Storage
The machine should not be stored for more than 6 months
with biodiesel in the fuel system. For longer storage time,
it is strongly suggested that only regular #2 diesel fuel is
used.
NOTE: if storage for longer than 6 months is necessary,
the engine must be run on regular #2 diesel for a minimum
of 20 hours to flush the biodiesel fuel out of the fuel system
prior to storage.
Biodiesel is highly hygroscopic and tends to collect water
more than diesel fuel. This increases the risk of algae
and bacteria growth which can cause severe damage to
the fuel injection system. Keep the machine fuel tanks
and on-site storage tanks as full as possible to limit the
amount of air and water vapors inside the tank. Drain
water from the tanks at least once a week.
NOTICE: use only CASE CONSTRUCTION approved
biocide additives on TIER4B engines with an exhaust
aftertreatment system.
Limited B10 biodiesel approval
CASE CONSTRUCTION approves the use of up to B10
on TIER4B engines only in Minnesota (or other States &
Provinces) where the state legislation mandates its us-
age during the months of April to September only and the
state legislation mandates strict compliance of the B10 to
specification
ASTM D7467 . The B10 must consist of a
blend of S15 #2D Diesel Fuel per ASTM D975 and B100
blend stock per ASTM D6751 only.
