cutting chain will provide kickback reduction when properly maintained.
For smooth and fast cutting, chain needs to be main- tained properly. The chain requires sharpening when the wood chips are small and powdery, the chain must be forced through the wood during cutting, or the chain cuts to one side. During maintenance of your chain, consider the following:

■Improper filing angle of the side plate can increase the risk of a severe kickback.
■Raker (depth gauge) clearance.
■Too low increases the potential for kickback.
■Not low enough decreases cutting ability.
■If cutter teeth have hit hard objects such as nails and stones, or have been abraded by mud or sand on the wood, have service dealer sharpen chain.
NOTE: Inspect the drive sprocket for wear or damage when replacing the chain. If signs of wear or damage are present in the areas indicated, have the drive sprocket replaced by a Ryobi Service dealer.
HOW TO SHARPEN THE CUTTERS
See Figure 34 and 35.
Be careful to file all cutters to the specified angles and to the same length, as fast cutting can be obtained only when all cutters are uniform.
1.Wear gloves for protection. Properly tension the chain prior to sharpening. Refer to “Chain Tension Section” earlier in this manual. Do all of your filing at the
2.Use A 5/32 in. diameter round file and holder.
3.Keep the file level with the top plate of the tooth. Do not let the file dip or rock.
4.Using light but firm pressure, stroke towards the front corner of the tooth.
Lift file away from the steel on each return stroke.
