Maintenance
Note:
Determine the left and right sides of the machine from the normal operating position.
Important:
You can tip the machine backward or on its side to clean or service it, but no longer than 2 minutes. If
you hold the machine this position for too long, fuel can drain into the crankcase and damage the engine. Should
this happen, perform an extra oil change on the engine. Then turn the engine over a few revolutions with the starter
handle before starting the engine again.
