control on the engine to “CHOKE”. Move the
throttle control to halfway between “SLOW” and

4. Grasp the starter grip and pull slowly until the
starter engages and then pull the cord rapidly to
overcome compression, prevent kickback and
start the engine. Allow the cord to recoil slowly.
Repeat if necessary.

throttle to produce the amount of sweeping power
required.
