CHAIN MAINTENANCE
See Figures 30 - 31.
WARNING:
Remove the battery pack and make sure the
chain has stopped before you do any work on
the saw to avoid accidental starting and pos-
sible serious personal injury.
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
maintained properly. The chain requires sharpen-
ing when the wood chips are small and powdery,
the chain must be forced through the wood dur-
ing 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 dam-
age 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 Figures 32 - 33.
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.
WARNING:
The saw chain is very sharp, always wear pro-
tective gloves when performing maintenance
to the chain to prevent serious personal injury.
Properly tension the chain prior to sharpening.
Refer to Adjusting the Chain Tension earlier in
this manual. Do all of your filing at the mid-point
of the bar.
Use a 5/32 in. diameter round file and holder.
Keep the file level with the top plate of the tooth.
Do not let the file dip or rock.
