8. Operation

OP3

OP4

NOTE

In case of restarting immediately after stopping the engine, pull the starter knob with the choke knob pushed in (choke open).

4.Push in a decomp valve on right side of the machine. (OP3)

(1) Decomp valve

NOTE

In case a starter rope felt to be heavy, check if the decomp valve is pushed in.

5.Place the machine on stable ground and confirm that there is no obstacle around the cutter blade. As in the left Fig., securely hold the machine with left hand and right foot, and pull the starter knob. Pull the knob lightly in the beginning and then hard when it becomes heavy. (OP4)

IMPORTANT

Do not fully pull out the rope at once or let the knob go for free return as those may cause failure of the starter.

6.When initial combustion noise is heard, pull the throttle lever slightly to return the choke knob to the first stage position, press the decomp valve, and pull the starter knob again.

IMPORTANT

By pulling the starter rope repeatedly with choke knob pulled out position, the engine may have difficulty to start due to excess fuel. In case the engine does not start though the rope is repeatedly pulled, push in the choke knob and pull the rope until it starts. Otherwise, remove a spark plug to dry its electrode, and reassemble. Try again the starting operation.

7.When the engine is started, lightly pull the throttle lever and unlock the start setting button.
