WARMING UP ENGINE

1) Before beginning operation, allow the

engine to warm up at idling speed for

3 minutes. (Failure to do this will

shorten engine life.)

2) Be sure the low oil pressure warning

indicator goes off after starting the

engine.

3) Check for a steady flow of water from

the cooling-water pilot hole.

cC

8 If the low oil pressure indicator does

not go off after the engine starts, stop

the engine. Otherwise, serious engine

damage could occur. Check the oil level

and add oil if necessary. If the cause for

the low oil pressure warning indicator

cannot be found, consult your Yamaha

dealer.

8 A continuous flow of water from the

pilot hole shows that the water pump

is pumping water through the cooling

passages. If water is not flowing out of

the pilot hole at all times while the

engine is running, do not continue to

run the engine. Overheating and seri-

ous damage could occur. Stop the

engine and check to see if the water

inlet on the lower casing is blocked. If

the problem cannot be found and cor-

rected, consult your Yamaha dealer.

NOTE:

After the engine starts, warm-up opera-

tion is automatically controlled by

Electronic Fuel Injection system.

Automatic control is canceled if the throt-

tle is opened more than halfway.
