How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle. If a fuel line is cracked, it will leak gasoline and draw air from outside into the fuel line. If the line is leaking fuel, it needs to be replaced.
The throttle and lock safety feature prevents accidental throttle engagement. Both the throttle and and lock must be pressed in order for the chain to move.
To reduce the risk of kickback injury use STIHL reduced kickback bar and STIHL PM 1 (3/8″ Picco), RM 2 (0.325″) or PM 2 (3/8″) chain depending on sprocket pitch or other available low kickback components.
If your saw idles fine, and then bogs down when pressing the throttle, then adjust your `H` screw by unscrewing. This will increase the amount of fuel to the carburetor under load. If your saw idles fine, then runs lumpy with a lot of smoke when pressing the throttle, then adjust your `H` screw by screwing in.
STIHL recommends that you do not run your engine at wide open throttle without a load. A blower is under a load at all times, a trimmer is under a load as long as the trimmer head is in place and the line is to the correct length, while a chainsaw is under a load when the bar and chain are in a cut.
Generally, two-stroke chainsaw engines are built to conveniently run at full throttle without an engine breakdown. Therefore, running at any throttle speed below the full throttle is not advised. Cutting a thick wood or timber while running at a low speed or throttle can cause the blades of the chainsaw to become dull.
