New gas can be a help...especially if the old gas is a month or more old. More important are all the different things that can lead to a no-start scenario with your machine. By process of elimination, you have to take it step by step and try to rule out all the different causes. Remember, this is an internal combusion engine, very similar to your car engine in that regard (it just doesn't have any valves and burn oil with the gas). A no start or stalling out and dying condition are the most common malady in these forums. For a start, check carbon buildup in the muffler and on the screen in the back of it. It's easy to take the muffler off. Torx head fasteners bolt it to the exhaust port of the engine. Check the exhaust port for bad buildup. Never clean it off the engine with metal...scrape it with a wooden device. Remove the spark plug. Shine flashlight down into engine. Is there a lot of carbon on top of the piston? Cleaning it up is a serious job if you remove the engine to do so.
Here is a Zama pdf file troubleshooting most possible mechanical and carburetor related problems. This is good reading and there is a lot to learn here. The charts are about 1/3 of the way into this file. Make sure all the screws and bolts to the carb and engine are tight and that the air filter is clean.

Take the air filter off of it and spray some carburetor/choke aerosol spray cleaner into it and immediately try to start it.

You may have too much string out. Try cutting off some if your machine auto cutting blade is gone or really dull

Have you checked the plug to the power socket,and the lead that comes with the machine,check these connections as sometimes they become corroded,have you tried to contact the seller?rgds

If you have the model number, we could assist better.

There should be a hole in the pulley that holds the starter rope in the starter/recoil unit. If you have taken the machine apart to that point, yes, there is only one way to reassemble it.
You will have to wind the starter recoil without the rope installed on itabout 5-6 complete revolutions to "pre-load" tension on the spring-steel starter spring, then lock the pulley in place, insert the pull rope and tie it off so it can come back out and then release the pulley, letting it draw in the new starter cord. Make sure you have the handle installed so it will stop when it gets to the body of the engine cover.

The title states that this is an electric trimmer, therefore no gas or oil is needed.

Does it not hold a charge, or will the charge not indicate "fast charge"? I had to apply a initial jump charge on the battery to get it up to 20 volts, then I put it in the Ryobi Charger, and it started charging it.

there is infact a small directional arrow on the head but if you cannot find it it should be replaced anti clockwise

well its not going to start with electric because the cord is out of it...
just take it apart becareful do not pull the recoil out or your in a mess....
but this should help you out if you need to know more just ask...

The knob is definitely a LEFT handed thread....try this...take a shop rag and double it. Wrap it around the red knob and with a pair of channel locks or large pliers...carefully turn it in a CLOCKWISE direction it should break loose...some crud or water may have gotten in the threads of the cap and are binding it....good maintenance tip....when you get it loose clean the threads and lubricate them with a small amount of grease on the threads....won't stick again...hope this helps...;-D

If you can get it going by "playing" with the cord, that is the problem. Either get a new cord or strip the one you have and find the break, repair it and go to work! Good luck...Lee

battery has had it buy new one
