20 Most Recent Ryobi 15" Electric Factory Reconditioned Trimmer (ZRRY41002) - Factory Reconditioned Questions & Answers

if it's both of them then i am thinking you have a faulty charger. i have seen mine do that, i got a new charger and it worked properly.

Well, I don't know just yet.
Is the smoke blue and does it do it the whole time that it is running? If so, the gas could be mixed too rich.
Exactly how long does it run? If it is 10-15 minutes then it is probably your gas cap that is the problem. It is clogged with dirt. The gas cap must be able to breathe or the carburetor won't get the proper gas flow.

Check the outer tube has not moved forward out of its housing at the engine end as this would make the inner too short.

If it was just bought new I would take it back and let them deal with it.

Check on the web. The Ryobi battery is made by Hawker Energy. They call it the Cyclon sealed lead-acid battery. The part number for the Ryobi specific one (OEM) is 0859-1008, but the generic number for the same thing seems to be 0859-1008. I found it on several web sites for $55-$65 + shipping. I have not bought it yet, but the best price that I found was here: http://www.bestlaptopbattery.com/viewbattery.cfm/Sealed-Lead-Acid/All-vendor/0859-1008.htm

I have no connection with this company and have not yet ordered from them. It's the best price that I found ($62 including shipping), but I'm still not sure if it's worth it.

TJ, I've had the same problem since yesterday and I found the solution (lots of googling - that's how I found your post BTW).
It turned out that the switch malfunction is a common problem.

The part number for the FA3-4 switch is:

ut41002a-36 ("switch assembly")

Available here (thru Amazon):
http://factorylawnandgarden.com/product/553902/B000PLVCX8/SWITCH_ASSEMBLY_UT41002A_36/

It's a Homelite part, which is identical to Ryobi.

Here is the manual showing it (part 6):

Here is the thread with the solution:

This was answered in a previous solution

does it blow out alot of blue or dark exhaust? if so adjust screw on carberator as it maybe be running rich, if this doesnt work have the switch checked for malfunctioning

Take a large adjustable wrench and grip the bump head (black plastic) at the same time use your other hand to hold the line spool (orange plastic) rotate the the wrench in a counter clockwise direction slowly and carefully to ensure you are not applying force in any other plane than parallel to the spool or you may damage the bump head threads just until it breaks free. Remove the rest of the way by hand. This happens to me from time to time. If you care you can put a small amount of graphite on the bumphead threads to allow it to come off with hand pressure.

Ryobi trimmers I have had use a 32:1 oil mix. Just pick up a little bottle of Ryobi 2-cycle oil and read it to see that it will give a 32:1 mix in a gallon of gas. Pour it into a gallon of gas, and maybe a little fuel stabilizer too, shake it up and you should be good for the season.

Maybe try using a pair of channel-lock pliars or a pair of vise grip pliars on the thing. Please vote on this solution.
