Fuel
Recommended Fuel
Use commercially available diesel fuel (JIS K2204).
Note: Some Class-A heavy oils are unsuitable for
use in the Mitsubishi diesel engine. Use fuel
that meets the Use Limit Property Guideline
for Diesel Fuel. If the engine is continuously
used for many hours, refer to the recom-
mended use limit.
It is necessary to use fuel that has a pour point suit-
able for the ambient temperature. Choose the fuel
type from the chart on the right.
Handling Fuel
When using fuel kept in a storage tank, allow it to sit
for more than 24 hours so dust and water can settle at the bottom. Then, use clean fuel from the upper layer.
Fill the fuel tank or service tank after each work day. This prevents water from mixing with fuel in the tank and
gives time for dust and water to separate and settle at the bottom of the tank.
Before removing the caps from the drum and tank, clean the areas around the caps thoroughly. Also clean
your hands and the hose used for refueling. When a hand-operated pump is used, be careful not to pump
water or sediment accumulated at the bottom of the storage tank.
Be sure to pour fuel through a strainer. Use of a clean, lint-free cheesecloth is recommended.
