■ Fit the bar flush against the mounting surface so that
the bar studs are in the long slot of the bar.
■ Replace the clutch cover, ensuring that the adjusting
pin in the clutch cover is in the bar chain tensioning
pin hole.
■ Replace the clutch cover and rotate clutch cover lock
knob just enough to hold the cover in position.
NOTE: The bar must be free to move for tension
adjustment.
■ Remove all slack from the chain by rotating the chain
tensioning dial clockwise until the chain seats snugly
against the bar with the drive links in the bar groove.
■ Lift the tip of the guide bar up to check for sag.
■ Release the tip of the guide bar and turn the chain
tensioning dial clockwise. Repeat this process until
sag does not exist.
Hold the tip of the guide bar up and tighten the clutch

tensioned when there is no sag on the underside of

securely. Ensure that the chain will rotate without
binding.

CHAIN MAINTENANCE

See figure 45 - 47.
WARNING
Check that the switch is in the STOP "O" position before
you work on the saw.
Use only a low-kick-back chain on this saw. This
fastcutting chain provides kick-back reduction when
properly maintained.
For smooth and fast cutting, maintain the chain 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 the chain, consider the following:
■ Improper filing angle of the side plate can increase the
risk of a severe kick-back.
■ Raker (depth gauge) clearance.
– Too low increases the potential for kick-back.

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.
NOTE: If you do not fully understand the correct procedure
for sharpening the chain after reading the instructions that
follow, have the saw chain sharpened by an authorised
service centre or replace with a recommended low-
kickback chain.
SHARPENING THE CUTTERS
See figure 48 - 51.
Be careful to file all cutters to the specified angles and to
the same length, as fast cutting can only be obtained when
all cutters are uniform.
The saw chain is very sharp. Always wear protective
gloves when performing maintenance to the chain.
■ Tension the chain prior to sharpening.
■ Use a 4 mm (5/32 inch) diameter round file and holder.
■ Keep the file level with the top plate of the tooth. Do not
■ Using light but firm pressure, stroke towards the front
■ Lift the file away from the steel on each return stroke.
■ Put a few firm strokes on every tooth. File all left-hand
■ Remove filings from the file with a wire brush.
A dull or improperly sharpened chain can cause
excessive engine speed during cutting which may result
in severe engine damage.
Improper chain sharpening increases the potential of
kick-back.
