the throttle lever lockout (22) pressed and immediately release
the throttle lever (23). Then half-throttle is disengaged. (Fig. 18)

(Fig. 2)
Allow the engine about 2-3 minutes to warm up before subjecting
it to any load.
Do not run the engine at high speed without the load to avoid
shortening the life of the engine.
Starting the warm engine
Use only 1, 2, 7, and 9 of the starting procedure for a cold engine.
If the engine does not start, use the same starting procedure as for
a cold engine.
Chain lubrication test (Fig. 19)
Check that chain oil is discharged properly. When the saw chain
starts to revolve, point the head of the guide bar to a stump, etc.,
and pull the throttle lever to perform high-speed operation for around
10 seconds. If chain oil is sprayed over the stump, it is discharged
properly.
