Make sure the cutting attachment is clear of obstructions.
(d)Depressing the lock lever, pull the throttle lever fully and depress the throttle lock button. While depressing the throttle lock button, release the throttle lever and the lock lever. Now the throttle stays at high idle (starting speed).
(e)While firmly holding the outer tube with one hand, pull the recoil starter handle upward with your other hand.
Pull slowly at first until you feel the starter engage, then pull quickly to start the engine. Do not pull the starter rope to the end of its travel.
CAUTION!
Pulling the starter rope to the end of its travel may damage the starter mechanism.
IMPORTANT!
Repeated cranking of the engine with the choke CLOSED (“ “) will lead to engine flooding. If the engine fails to start after several attempts, move the choke lever to the OPEN position and continue cranking.
(f)When the engine first fires, gradu- ally return the choke to OPEN
(“ ”) position if you have not al- ready done so.
• If the engine stops before the choke is fully open, restart with the choke closed.
