Hedge trimmer starts fine then stops after 5 minutes

electric hedge trimmers have 2 switches to press before it runs
one is the trigger that you pull and the other is in the handle that you hold in your left hand
both have to be on before it starts
it is a safety feature to stop operators cutting off their fingers

If the engine starts 'fine" then it has not seized.

Many, if not most, hedge trimmers are , for safety, equipped with a "CENTRIFUGAL CLUTCH" between the engine and the blade to prevent blade operation unless the engine is at full RPM.

IF your machine is so equipped, it's possible that the clutch is worn and slipping so badly that the blade can't move.

If you are not using fresh fuel, change the fuel and replace. Although you will still have fuel in the carburetor and the lines. If you do not remove and drain it may take a little while to get it to start, but should be a lot less then what you are doing now.

Have you changed the H T lead and then check the cut of swicth for faulty wireing

Check the air filter, replace the fuel if it is last year's, clean the spark plug or replace. Also lube the blade. Good luck...Lee

Hello. Get a can of starter fluid and a helper. Spray some into the air cleaner and start it up. Have your helper continue to spray a little starter fluid to keep it running for a minute or so. This will clear whatever blockage you have. Once it sounds like it is running well stop adding starter fluid and see. Joe

I have a Troy-Bilt gas powered hedge trimmer. My blades would not move. After tearing it apart, I found that there were some spacers under the 5 or 6 screws along the blades. These spacers are steel and designed so that you don't overtighten the screws. However, around those steel spacers, there is a teflon type material that makes the oval shape of the slot. That teflon had fallen apart and lodged so that the blades would not move. I removed the teflon and put the spacers back in and it now works fine. There is a little play between the spacer and the edge of the slot and it will probably eventually wear out but at least I got a few more cuttings off of it.

Check your fuel lines. It is probably getting air into the system. Also check inside the gas tank to make sure the fuel pick up line is still attached.


If you need more assistance please provide an exact model number and I can better help you.

could be the coil

The problem you are experiencing is the coil. I had the same problem and confronted a freind that works on small engines. I asked him if the coil could be the problem and he gave me one to try out of another trimmer he had for parts. It is running well. The problem I now have is the blade tang that moves it back and forth broke. Now I'm trying to locate one of them.
