5. While holding the unit firmly, pull out the starter rope

quickly until engine fires. (OP4)

• Avoid pulling the rope to its end or returning it by

releasing the knob. Such actions can cause starter
failures.

before starting operation.

stopping it, leave the choke open (OP2) and push
the primer pump several times (OP4).

to excess fuel. When the engine failed to start after
several attempts, open the choke and repeat pulling
the rope, or remove the spark plug and dry it.
