Ryobi One+ 18V Cordless OCS1825 Questions & Answers

The chain sprocket is a press fit . When it wears it doesn’t hold . Ryobi should have used a key to secure the sprocket but that involves cutting into they profit margins . I fixed mine by glueing sprocket on with Loctite 263

thanks. I'll give it a try. Are there any problems pulling it apart?

I have the same problem and I'm selling it I bought a 6inch brushles cordless on ebay and I've.chopped 13 medium palm trees down with not too much effort all on one chain I bought a spray can of canola oil and spray on chain frequently tensioning this little saw is so easy

I retention mine before going out bush each time. Easy enough to do. Just release the hex bolt on the side of the chainsaw and then pull the front chain assembly forward and then retention the hex bolt.

You haven't indicated how long you used the saw for during the first three outings. If you flogged it for several hours at a time during each outing, the motor may have been stressed beyond an acceptable limit. However it could also be a bad battery connection seeing that it continues to work intermittently - or the battery itself may have developed a fault; unfortunately they often do - I've already had three Ryobi's which failed within a short period of time and just outside the warranty period wouldn't you know. Make certain the battery is pushed completely home to begin with; if it is, then I'd take the saw back for a replacement because it's likely to have developed a fault. I can't complain about the one I got - it's done great for what it was purchased for - clearing away the odd small tree and branches which had fallen across fences and access tracks along property boundaries. Just need to carry a few batteries on standby.

Same for me. Being that the chain tension system on these things seem just enough to be adequate enough for a new unstretched chain, I doubt it can be altered once the chain has stretched - and it doesn't take long to do so. You could try removing a link, but I thought being such a small chain anyway I wasn't certain I could remove one without the chain becoming too short to put back on - but give it a go and let us know! I assume that being one of the cheaper versions of an electric chainsaw - and you only get what you pay for - a really good chain tension system is probably not part of the deal. I replaced the original chain with a second chain and this worked to solve the slackness in the tension I had - until the next time I guess. Maybe I should try to remove a link and see for myself

thanks Waz, will give that a go. A bit disappointed that the engineering crew who designed it didn't rectify this problem before releasing it to the market otherwise a good little saw.

All part of their business plan Wayne. All part of the plan to get your money! They're pretty much aware of all the faults before they place it on the market, but their 'Dracula' strategy is to suck us dry before we wake up!

Most problems in this department are created by the vacuum release valve system used in a chainsaw to supply oil to the bar of your chainsaw. Oil reservoirs often build up pressure while using the saw and until this pressure equalizes, oil keeps seeping past the valve. Very often though, the valve system is too weak to seal off the oil flow completely - or it fails to close properly due to dirt being in the oil itself. Other reasons are simply due to poor design. Whatever. it's no big deal - just a pain to keep having to empty the oil reservoir every time after use. I've used McCulloch, Jonsered, Stihl and Husqvarna chainsaws over the years and they all leaked oil when not in use to varying degrees. The small Ryobi Cordless I purchased for the wife for pruning does the same even though it requires hand pumping. No surprise at all!

Poor design!

Unfortunately, until Ryobi re-designs a battery that releases itself more easily, I think you're going to be stuck with it. It's always been a problem for me as well and I don't consider myself weak in the hand department at all. The problem they have is that the battery is too wide and the release clips seem to need an extraordinary amount of force when squeezing them until the battery comes free! Unless you have very large hands and the strength of a gorilla, it will always be the case that Ryobi batteries will be difficult to remove. With arthritic hands, the only thing I can suggest is to get hold of something like a VICEGRIP 'C' clamp from the hardware shop and use it to close the clips up, then pull out the battery. The problem though, is that you'd need to be careful not to crack the battery case in the process. Ryobi really need to get onto this.

Thank heaps for replying. Not just Ryobi batteries as I also have another brand with the same issue. Sigh....

Take off the cap that covers the oil reservoir then remove/pull out the piece of foam inside the reservoir itself. If you don't, you'll be there forever trying to fill it. I did it to mine and haven't had any issues other than the oil might tend to leak out on it's own overnight! I simply empty the oil in mine back into a container after finishing with the saw.

Did you get an answer? I too have bought a brand new one and started to prepare it today but as much as I press the oil bulb, no oil comes into the chain. I won’t use it until I have an response to our question.

Yes. I removed the nut on the chain tensioner and found a small hole where the oil was supposed to come out. The hole was blocked, apparently from faulty plastic moulding in the first place. A pin managed to break the hole through and it works fine now. Hope this helps you.

Flat battery - faulty switch - or the saw has developed a fault in which case it may be covered under warranty!

I didn't notice that in the manual. But i had a major issue with mine where the "gearbox" had a screw come loose. So I had to pull it apart and it was full of grease

I see , yes that makes me wonder if that grease needs replenishing . I watched some videos on the 18V Chainsaw external link  & in the comments some people say even with the petrol ones its better to not grease them . They say the oil will do the job instead ,even in the ones with a grease hole so you may be right. I think I'll ring Ryobi . Ok , I just rang Ryobi 1300697624 Aus. Helpline, they said the chainsaw comes with the grease pre-lubed & ready to go , & that after about 100 hours of use you should then check the hole where you add grease . After purchase this hole will have a bit of grease sitting in sight in the open hole , if that grease has disappeared then probably the grease has been used up so then add some grease ,& anyway they said you should add some grease after every 100hours of use .

Sound about right!

I found the chainsaw does leak if upside down or possibly at certain angles. I store mine flat now to prevent this. It is a bit of a design fault I believe.

Thanks Robert, love the product except for the oil leak

Yep the leaking is very annoying and impractical. The manual says drain all oil out after every use. Poor design.

It's the same with every chainsaw I've ever used, both battery and petrol - par for the course I'm afraid. Tipping the saw upside down only encourages the oil to leak out of the airhole on the filler cap itself.

Not funny I know - but knowing Chinese might help!

None that I'm aware of - and I've used lots of different ones. Just something you have to put up with. I'd suggest it might be something to do with designing and fitting an accurate automatic oiling system, which would raise the cost of a saw significantly for not much benefit. Oiling a chainsaw using a manual application gets to be second nature after a while.

That's normal... most chainsaws do that in my experience. I empty the oil before storing it and put a rag under the bar to catch drips. You can buy a tray for this purpose on eBay as well

A standard 18volt rryobi bat available from bunnings

Jem, it will run on any of the Ryobi One + batteries (Bunnings). The difference in Amp hour (Ah) is reflected in the price, it will run on the smallest (1.3 Ah) but it won’t run as long as it will on the 5 Ah, which is a lot more expensive, it’ll run for a day’s work on the 5 Ah

Lol It lasts 30minutes on a 5Ah

Only requires chain oil

I've found Ozito tools to either cut or grind etc well or not to work well. I bought the ozito electric pole chainsaw - 240volt and it has been tremendous. If you are going to cut reasonably thick wood, I would stay clear of the battery chainsaws. If you're going to buy a 2 stroke machine, try to drain all the fuel after you use it before you store it. Carburettors dont like fuel in them while in storage. I've had problems with every 2 stroke if I dont use it consistently. If you're using it on your block, I'd get a 240 volt machine and an long extension cord. The machine will last for years and you wont have batteries that dont like storage in a discharged state.
