damaged by overheating.

• Never twist the starter cord around your hand.
• Avoid pulling the starter rope out to its full extent and allowing the starter rope
to snap back. This will prevent premature damage to the starter.
• Do not let a person stand near the blower or the exhaust port.
5. Once the engine is running, gradually open the choke if it was set closed, and let the
engine run at idle speed for a minute to warm it up.
NOTE
When the engine fails to start after several attempts due to overchoking, open
the choke and repeat pulling the rope.
ADJUSTING IDLE SPEED
• The idling speed is set for 2000 rpm at the factory. If it is necessary to adjust the idle
speed, use the adjustment screw on the top side of carburetor.
