1.3 Fuel oil, lubricating oil and cooling water
1.3.1 Fuel oil
IMPORTANT:
Only use the recommended fuel to obtain the best engine performance and prevent damage of parts,
also prevent air pollution.
(1) Selection of fuel oil
Use the following diesel fuels for best engine performance:
BS 2869 A1 or A2
Fuels equivalent to Japanese Industrial Standard, JIS. No. K2204-2
Fuel cetane number should be 45 or greater
(2) Fuel handling
• Water and dust in the fuel oil can cause operation
failure. Use containers which are clean inside to
store fuel oil. Store the containers away from rain
water and dust.
• Before supplying fuel, let the fuel container rest for
several hours so that water and dust in the fuel are
deposited on the bottom. Pump up only the clean
fuel.
(3) Fuel tank
Be sure to attach a drain cock, precipitation trap and
primary strainer to the fuel tank as shown illustration
right.
1.3.2 Lubricating oil
IMPORTANT:
Use of other than the specified engine oil may cause
inner parts seizure or early wear, leading to shorten
the engine service life.
(1) Selection of engine lube oil
Use the following engine oil
• API classification ......... CD or better
(Standards of America Petroleum Institute)
• SAE viscosity ......... 10W-30 or 15W-40
(Standard of Society of Automotive Engineering)
Engine oil with 10W-30 can be used throughout the
year.
(Refer to the right figure.)
Pump up only the fuel
in the upper half to
leave dregs near the bottom
Filler port
Fuel return
connection
Outlet
(to engine)
Drain cock
Primary
strainer
Selection of viscosity
(SAE Service grade)
Atmospheric temperature ( C)
10W-30/15W-40 can be used
almost throughout the year.
