Handling and Storing Diesel Fuel
CAUTION: Reduce the risk of re. Handle fuel
carefully. DO NOT ll the fuel tank when engine
is running. DO NOT smoke while you ll the
fuel tank or service the fuel system.
Fill the fuel tank at the end of each day's operation to
prevent water condensation and freezing during cold
weather.
Keep all storage tanks as full as practical to minimize
condensation.
Ensure that all fuel tank caps and covers are installed
properly to prevent moisture from entering. Monitor water
content of the fuel regularly.
When using biodiesel fuel, the fuel lter may require more
frequent replacement due to premature plugging.
Check engine oil level daily prior to starting engine. A
rising oil level may indicate fuel dilution of the engine oil.
IMPORTANT: The fuel tank is vented through the
ller cap. If a new ller cap is required, always
replace it with an original vented cap.
When fuel is stored for an extended period or if there is a
slow turnover of fuel, add a fuel conditioner to stabilize the
fuel and prevent water condensation. Contact fuel supplier
or authorized Hitachi dealer for recommendations.
Biodiesel Fuel
Biodiesel is a fuel comprised of mono-alkyl esters of long
chain fatty acids derived from vegetable oils or animal
fats. Biodiesel blends are biodiesel mixed with petroleum
diesel fuel on a volume basis.
Before using fuel containing biodiesel, review the
Biodiesel Use Requirements and Recommendations in
this operator's manual.
Environmental laws/regulations may encourage or
prohibit the use of biofuels. Operators should consult
with appropriate governmental authorities prior to using
biofuels.
Biodiesel users in the U.S. are strongly encouraged to
purchase biodiesel blends from a BQ-9000 Certied
Marketer and sourced from a BQ-9000 Accredited
Producer (as certied by the National Biodiesel Board).
Certied Marketers and Accredited Producers can be
found at the following website: http://www.bq-9000.org.
Biodiesel concentrations up to a 5% blend (B5) in
petroleum diesel fuel can be used in this engine.
The petroleum diesel portion of biodiesel blends must
meet the requirements of ASTM D975 (US) or EN 590
(EU) commercial standards.
Request a certicate of analysis from a fuel distributor to
ensure that the fuel is compliant with the specications in
this operator's manual.
When using biodiesel fuel, the engine oil level must be
checked daily. If oil becomes diluted with fuel, shorten
oil change intervals.
The following must be considered when using biodiesel
blends up to B5:
•
Cold weather ow degradation
•
Stability and storage issues (moisture absorption,
oxidation, microbial growth)
•
Possible lter restriction and plugging (usually a problem
when rst switching to biodiesel on used engines)
•
Possible fuel leakage through seals and hoses
•
Possible reduction of service life of engine components
IMPORTANT: Raw pressed vegetable oils are NOT
acceptable for use as fuel in any concentration
in this engine. Use of raw pressed vegetable
oils could cause engine failure.
Testing Diesel Fuel
A fuel analysis program can help to monitor the quality
of diesel fuel. The fuel analysis can provide critical
data such as cetane number, fuel type, sulfur content,
water content, appearance, suitability for cold weather
operations, bacteria, cloud point, acid number, particulate
contamination, and whether the fuel meets specication.
Contact an authorized Hitachi dealer for more information
on diesel fuel analysis.
