AIR CLEANER ON ENGINE
Since the air cleaner on this engine is a dry type, never apply oil to it.
1. Open evacuator valve (see engine manual) once a week to remove large particles of dust and dirt.
2. Wipe the inside of the air cleaner with a cloth if it gets wet or dirty.
3. Avoid touching the element except when cleaning.
4. When dust adheres to the element, gently tap element on flat surface.
5. When carbon or oil adheres to the element clean according to engine manual.
6. Replace the element every year or every 6 months.
7. IMPORTANT - Make sure wing bolt for the element is tight enough. If it is loose, dust and dirt may be
sucked in, wearing down the cylinder liner and piston ring, resulting in poor power output.
Do not use petroleum solvents, e.g.., kerosene, which will cause cartridge to deteriorate. Do
not use pressurized air to clean cartridge. Pressurized air can damage cartridge.
FUEL
CHECK EMISSION REGULATIONS OF YOUR AREA
With Emission control now in effect diesel fuel specification type and sulfur content % (ppm) used must be in
compliant with all applicable emission regulations for the area in which the engine is operated.
Use of diesel fuel with sulfur content less than 0.10% (1000 ppm) is strongly recommended.
If high sulfur fuel is used, change oil and oil filters twice as often.
DO NOT USE Fuels that have sulfur content greater than 1.0% (10000 ppm).
Diesel fuels specified in EN 590 or ASTM D975 are recommended.
Since KUBOTA diesel engines of less than 56kW (75 hp) utilize EPA Tire 4 and Interim Tier 4 Standards, the use
of low sulfur fuel or ultra low sulfur fuel is mandatory for these engines, when operated in US EPA regulated ar-
eas. Therefore, use No.2-D S500 or S15 diesel fuel as a alternative toe No. 2-D for ambient temperatures below -
10°C (14° F).
