Ryobi is not a make, it is a marketing brand
Ryobi can be made by any one of 1000 different factories as the manufacture is contracted out .
Most Ryobi products are designed not the be repaired right down to snap in parts that can not be removed without breaking them .
On top of that depending upon the manufacturere there may or may not be an IPL let alone any sort of repair manual or even specifications .
Like most I do not repair Ryobi for 2 reasons
1) can not get parts unless it is rebadged from a major maker
2) cost of repair almost always is higher than the replacement price particularly for hand held items
Silly example for an 18" walk behind
Blades $ 30
Air filter $ 45
Fuel filter $ 14 ( Aftermarket $ 6.50 )
Fixed rate service charge $ 45
New mower $ 110
Note these are $ AUS .
The Ryobi Aust only carry limited parts for the models they imported and all of the big retailers do direct imports for various Ryobi outlets in HK, China, Korea, Vietnam, The Phillipines & even USA all of which are considered to be "grey imports"
Ryobi themselves do not repair anything they just replace items that failed under warranty and sell off the returned items at auctions .
SO no real purpose for a dedicated Ryobi section
