Chain Maintenance - Ryobi RY40050 Manuel D'utilisation

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 OILER
See Figure 18.
 Use Premium Bar and Chain Lubricant. It is
designed for chains and chain oilers and is
formulated to perform over a wide temperature
range with no dilution required.
 Remove the cap and carefully pour approxi-
mately 2 oz. of bar and chain lubricant into the
bar lube reservoir.
 Replace the cap and tighten securely.
 Check and refill the bar lube reservoir every time
the pole saw is used.
NOTE: Do not use dirty, used, or otherwise con-
taminated lubricants. Damage may occur to the
oil pump, bar, or chain.

CHAIN MAINTENANCE

See Figure 19.
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
increase the risk of a severe kickback.
 Depth gauge (or raker clearance) setting
determines 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.
