Do not pull the recoil starter to the end of the rope travel. Pulling the recoil starter to the end of the rope travel can damage the starter.

6.When the engine starts, slowly move the choke lever to the “OPEN” position. (If the engine stops after the initial start, close the choke and restart.)

7.Operating the throttle will automati- cally disengage the fast idle setting.

If the engine fails to start after several attempts with the choke in the closed position, the engine may be flooded with fuel. If flooding is suspected, refer to the ”Starting a Flooded Engine” sec- tion of this manual.

When the Engine Starts...

■■After the engine starts, allow the engine to warm up at idle 2 or 3 min- utes before operating the unit.

■■If the engine does not continue to run, repeat the appropriate crank- ing procedures for a cold or warm engine.When the engine starts, clear excess fuel from the combustion chamber by accelerating the engine several times with the throttle lever.

■■Advancing the throttle makes the cut- ting attachment move faster; releas- ing the throttle permits the attach- ment to stop moving. If the cutting attachment continues to move when the engine returns to idle, carburetor idle speed should be adjusted (see “Adjusting Engine Idle”.).

If the engine does not start

■■Repeat the appropriate starting pro- cedure for a cold or warm engine.

■■If the engine still fails to start, use the procedures for “Starting a flooded engine.”
