First Time Start-Up
 If a saw is left in the fast idle position with the chain brake 
engaged for even a very short period of time it may overheat 
the clutch and chain brake components and possibly ruin the 
tank housing as well
 To stop the engine raise the Master Control Lever™ to the 0 
(off) position, #4 in the picture

First Time Start-Up: Warm Up 
 After the engine has started and the chain brake has been 
released, slowly squeeze the throttle about half way open and 
then slowly release it back to idle
 Do this several times, for at least 20 seconds, to completely 
purge any remaining air from the carburetor circuits and to 
allow the chain lubrication pump time to prime the system with 
bar and chain oil
 Never allow any chain saw engine to run at full throttle without
a load, regardless if it is new or broken-in, for more than a few 
seconds
