The Stihl hedge trimmer has a 2-cycle engine, which requires the same basic maintenance as any small motorcycle.

It is critical that proper care and tune-ups are done with precision in accordance with the manual.

Proper care will ensure there aren’t any problems with hard starting or loss of power issues like there are with many different types of motor vehicles – minor repairs can fix these simple problem areas.

If you don’t do the proper maintenance, it might result in more major and costly repairs down the road so it’s important to follow instructions carefully while also considering getting a gas/oil mix that’s compatible with your trimmer before getting started.

Here we provide you troubleshooting guide about your Stihl hedge trimmer.

Stihl Hedge trimmer won’t start

Inspect the spark plug for signs of wear and make sure it hasn’t been damaged in any way. If it has a cracked insulator, is missing an electrode, or has carbon buildup around it, then you need to replace it with a new one. Spark plugs can be tested using a spark plug tester.

The sparking should be stronger than 25-centimeters (10 inches) from the tip of the plug if there aren’t any problems with your new ignition system while you have plugged it in.

The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the hedge trimmer for a long period of time.

Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting.

Try cleaning it out with carburetor cleaner before you rebuild or replace anything else.

Stihl Hedge trimmer runs rough

Clogged fuel filters can cause problems with hedge trimmers. A clogged fuel filter is usually caused by leaving old fuel in the hedge trimmer over time, which can thicken and render it ineffective.

If you suspect your hedge trimmers have been running roughly due to a blocked fuel filter, drain the fuel tank and replace the fuel filter.

The air filter may be dirty or clogged. If the filter is clogged, the engine will receive too much fuel in relation to needing enough air. This makes the engine run roughly.

To remedy this and make your vehicle run smoothly, you can use a clean dry cloth to carefully wipe down all filters before they are put back into place.

Stihl Hedge trimmer starts then stalls

The spark arrestor is a device attached to the carburetor that captures dirt and grime. The screen becomes clogged with time and, if it is not removed, the entire engine could stop working, since fuel will not be able to flow correctly.

To fix this problem, see if you can find a replacement part so that you can remove the clogged one. In case you don’t, perhaps there’s another way in which you can reach the dirt inside – try cleaning it by hand.

Over time the carburetor may become clogged because of the fuel leftover in it. The fuel then tends to vaporize and create a thick substance, more like tar than gas, that can block up your engine completely.

If this happens to you, turn the hedge trimmer off right away then unplug it. Cleaning the carburetor first is a good idea if you suspect this has happened or even better – replace or rebuild the whole thing.
