When starting the engine when the ambient temperature is below 5°C (40°F),the engine will cycle through a period during

nonresponsive while the engine is in warm-up mode. Warm-up mode lasts between 30 seconds and 3 minutes depending
on the temperature. The throttle will become active after the engine has stabilized and is idling normally.

Do NOT operate the engine above 1500 rpm until the engine temperature gauge is above 40°C (100°F).
IMPORTANT:
• Do NOT operate the starter for longer than 15 seconds at a time.
