WARMING UP ENGINE

1)After the engine starts, return the choke knob to the half-way position. For approximately the first 5 minutes after starting, warm up the engine by operat- ing at one fifth throttle or less. After the engine has warmed up, completely push in the choke knob. (Failure to do so will shorten engine life.)

NOTE:

●If the choke knob is left pulled out after the engine starts, the engine will stall.

●In temperatures of –5 °C or less, leave the choke knob completely pulled out for approximately 30 seconds after starting. Then follow the standard instructions for warming up the engine.

CHECKING POINTS AFTER

STARTING ENGINE

●After the engine has warmed up, check that the engine idling speed is stable.

●Check that the low oil pressure warning indicator light is off. (Refer to “WARNING SYSTEM” section.)

●Check for a steady flow of water from the cooling-water pilot hole.

CAUTION:

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 serious damage could occur. Stop the engine and check if the water inlet on the lower casing is blocked. If the problem cannot be found and corrected, consult your Yamaha dealer.
