7 - MAINTENANCE
equipment you fit to a CASE CONSTRUCTION machine
that is found to have run with blend of NON-APPROVED
fuel (fuel that does not fulfill the requirements of
ASTM
D6751 or EN14214 ).
Biodiesel fuel usage conditions
You must stringently follow the biodiesel fuel usage con-
ditions. Incorrect application of the biodiesel fuel usage
conditions could lead to severe damage to the engine and
fuel injection equipment.
The main concerns about operation of equipment with
biodiesel fuels are:
• Filter and injector blockage caused by poor fuel quality
• 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 may harm the fuel injection system
NOTICE: CASE CONSTRUCTION Warranty will not
cover any problem in the engine fuel injection equip-
ment that results from non-compliance with the following
conditions for biodiesel fuel handling and biodiesel fuel
maintenance.
Purchase biodiesel fuel from a trusted supplier who
understands the product and maintains acceptable
fuel quality.
It is highly recommended that you use
biodiesel from BQ 9000 accredited suppliers to maintain
the quality and consistency of the fuel. The BQ 9000
Quality Management Program is accredited by the Na-
tional Biodiesel Board for producers and marketers of
biodiesel fuel. See the National Biodiesel Board website
at www.biodiesel.org for more information.
The supplier must pre-blend biodiesel fuel. Mixing
biodiesel fuel blends on-site can result in an incorrect
mixture that may 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.
Maintenance intervals
For machines using the all-electronic engines with a high-
pressure common rail fuel system, the use of biodiesel
blends up to B20 reduces the engine oil and filter change
interval to
250 h . For all engines, see the operator’s man-
ual for specific maintenance intervals.
Check all hoses, connections and gaskets to ensure in-
tegrity and cleanliness every 3 months or 150 hours of
operation, whichever comes first.
Regular oil sampling is highly recommended to monitor
for oil deterioration and engine deterioration.
NOTE: Oil sampling kits are available from your autho-
rized CASE CONSTRUCTION dealer.
When switching back from biodiesel to regular #2 diesel,
you should change all fuel filters, oil and oil filter even if
the changeover falls between routine service intervals.
Storage
You should not store the machine for more than three
months with biodiesel fuel in the fuel system. For longer
storage time, CASE CONSTRUCTION strongly suggests
that you use only regular #2 or
EN 590 diesel fuel.
NOTE: If you must store a machine for longer than 3
months, you must run the engine regular #2 or EN 590
diesel fuel for a minimum of 20 h prior to storage. This
will flush the biodiesel fuel out of the fuel system.
Biodiesel fuel is highly hygroscopic and tends to collect
water more than diesel fuel. Water collection increases
the risk of algae and bacteria growth that can cause se-
vere damage to the fuel injection system. Keep the ma-
chine fuel tanks and on-site storage tanks as full as possi-
ble to limit the amount of air and water vapor inside. Drain
water from the tanks at least once a week.
NOTICE: Use only CASE CONSTRUCTION approved
biocide additives.
