1. General 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.

Fuel return connection Filler port Fuel pipe To engine Sediment Drain cock 006761-00E 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.
Selection of viscosity (SAE Service grade) (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 or 15W-40 can be used throughout the year.
