Chain Maintenance - Ryobi P2508 Manual Del Operador

 Remove all slack from chain by turning the chain
tensioning screw clockwise, assuring that the
chain seats into the bar groove during tensioning.
 Tighten the chain cover screw securely.
 Return the combination wrench to the storage
area.
NOTE: Chain is correctly tensioned when there is
no slack on the underside of the bar, the chain is
snug, but it can be turned by hand without binding.
If chain is too tight, it will not rotate. Loosen the
chain cover screw slightly and turn chain tension-
ing screw 1/4 turn counterclockwise. Retighten
chain cover screw securely.

CHAIN MAINTENANCE

See Figure 19.
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.
For smooth and fast cutting, the chain needs to
be maintained properly. The following conditions
indicate that the chain requires sharpening:
 Wood chips are small and powdery
 Chain must be forced through the wood during
cutting
 Chain cuts to one side
During maintenance of the chain, consider the
following:
 Improper filing angle of the side plate can in-
crease the risk of a severe kickback.
 Depth gauge (or raker clearance) setting de-
termines the height the cutter enters the wood
and the size of the wood chip that is removed.
Too much clearance increases the potential for
kickback. Too little clearance decreases the size
of the wood chip thus decreasing the chain's
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.
