Diesel Lubricating Oil Note:
With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use
with a low-sulfur fuel used in on-road vehicle engines. When an off-road vehicle engine runs on a high-
sulfur fuel, it is advisable to employ the CF, CD or CE lubricating oil with a high total base number. If the
CF-4 or CG-4 lubricating oil is used with a high-sulfur fuel, change the lubricating oil at shorter intervals.

To check the engine coolant level, open and prop the engine cover and observe the coolant level in the coolant
overflow tank. If the level is low, add a 50/50 mix of water and the recommended type antifreeze. Clean the
radiator and oil cooler exteriors every 150 hours by washing with low-pressure water or using compressed
air.
