CHAIN MAINTENANCE
See Figures 32 and 33.
CAUTION:
Remove the battery pack and make sure the
chain has stopped before you do any work on the
saw.
Use only low-kickback chain on this saw. This fast-
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 mid-point of the bar.
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.
