Starting the Engine
IMPORTANT!
Engine ignition is controled by a two position switch mounted on the throttle housing labeled, "I" for ON or START and "O" for OFF or STOP.

1.Slide the ignition switch to the “ON” position. See Figure 9.
2.Set the throttle lever to the “fast idle”;
a.Squeeze the throttle lever toward the handgrip on the shaft tube.
b.Depress and hold the throttle lock button.
c.While depressing the throttle lock button, release the throttle lever. Then release the throttle lock button. See Figure 9.

3.Press the primer bulb until fuel can be seen flowing in the transparent return tube.
IMPORTANT!
The primer system only pushes fuel through the carburetor. Repeatedly pressing the primer bulb will not flood the engine with fuel.

Make sure the cutting attach- ment
is clear of obstructions!

5.While holding the outer tube firmly with left hand. Use your other hand to slowly pull the recoil starter handle until resistance is felt, then pull quickly to start the engine.
CAUTION!
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.
WARNING!
The cutting blades may move (oscil- late) when the engine is started. Keep away from the cutter assembly while starting the engine!
6.When the engine starts, slowly move the choke lever to the "OPEN" position. See Figure 13. (If the engine stops after the initial start, close the choke and restart.)

WARNING!
Never start the engine from the oper- ating position.
IMPORTANT!
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,
move the choke lever to the open position and repeatedly pull the recoil starter to remove excess fuel and start the engine. If the engine still fails to start, refer to the troubleshooting section of this manual.
When the Engine Starts...
nAfter the engine starts, allow the engine to warm up at idle 2 or 3 minutes before operating the unit.
nAdvancing the throttle makes the cut- ting attachment oscillate faster; releas- ing the throttle permits the attachment to stop oscillating. If the cutting attach- ment continues to oscillate when the engine returns to idle, carburetor idle speed should be adjusted (see "Adjust- ing Engine Idle" on the next page).
Starting A Flooded Engine
1.Disconnect the spark plug lead and use the spark plug wrench to remove the spark plug (turn counter clockwise to remove).
2.Slide the ignition switch to the “O” (STOP) position.
If the spark plug is fouled or soaked with fuel, clean the plug as necessary.
3.Open the choke (Figure 13) and fully depress the throttle lever with your left hand, then pull the starter handle rap- idly with your right hand to clear excess fuel from the combustion chamber.
4.Reinstall the spark plug and tighten it firmly. If a torque wrench is available, torque the spark plug to
5.Repeat the starting procedure for a warm engine.
6.If the engine still fails to start, refer to the troubleshooting section near the end of this manual.
