I have a Ryobi SS 26 the starter cord will not retract. I have change the starter spring but the cord will not retract after one pull. Could you send me instructions on how to change the starter spring and cord? The video on how to change the starter spring for a SS30 which is totally different from the SS26.

Thank you

Will

Hello joegab3,

You can order the spool with the line already in it. The part number you would need to order is 309562002 string head assembly.

Question: Spring Crazy

I am with you guys ... How do you put that spring back in place? Is it on top of the trigger or under it?

Take the spring with the single bend down and the hook end towards the trigger. Turn counterclockwise until you can slide the hook into the pocket of the trigger. Inside you'll see a pocket with a small slot. You turn the spring clockwise until the hook locks on then move the spring so that it is inside the hole. Drop the trigger onto the shaft and push the single bend into the pocket just about the shaft.

The Ryobi RY28040 actually has an air filter. It is Ryobi's version of an air filter on this model. It is part number 518766001 air filter base. As for the problems you all are having getting you engine to run correctly. We have an article and video that I hope will help you. Here is the link to it.

Question: Airbox Cover

lawnmomma

i just want to say that this cover has come off several times and luckily we've been able to find it but this time its gone. The weed-eater does'nt seem to work very well without it so i dont understand why it is'nt screwed on with at lest one tiny screw.

Question: Airfilter

does the airfilter just snap in?

Reply: Airfilter

Hi cmg,

The air filter base is held to the tool using the same screws that hold the carb to the engine. Tools that use this base don't have a filter. Ryobi considers the piece of window screen over the air intake opening to be the filter. Not the best design in my opinion...

I ordered a foam filter for mine because the factory screen is not suitable to keep the dust out. The filter from the link below comes with the part in the picture and also the middle section which fits the model RY28040 perfectely.

Ebay seller 'mowers4u' has a foam filter that fits perfect in the Model RY28040. It comes with two pieces, use the inner piece.

Review: Ryobi - RY28040 Weed Eater
1 star
Pissed Off
This is the biggest piece of trimmer crap I have ever bought. I should have been aware something was up when I saw the starting instructions, turn here, pump, pull, turn here, pump, pull, what kind a crap did I get into? I will never buy another Ryobi product even if it's the last manufacturer in China. It also has a horrible glide distance, I had to finish kicking it out to the street. It laid there all night, nobody ran over the dang thing or stole it! Oh, no wonder, it's a Ryobi!!
