Chain Maintenance - Ryobi RY10520 Manual Del Operador

CHAIN MAINTENANCE

See Figures 47 - 48.
CAUTION:
Check that the switch is in the STOP " O " posi-
tion before you work on the saw.
Use only a low-kickback chain on this saw. This
fast- cutting chain provides kickback 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 severe kickback.
 Raker (depth gauge) clearance.
• Too low increases the potential for kick-
back.
• Not low enough decreases cutting ability.
 If the cutter teeth hit hard objects such as nails
and stones, or are abraded by mud or sand on
the wood, have an authorized service center
sharpen the 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 indi-
cated, have the drive sprocket replaced by an
authorized service center.
NOTE: If you do not fully understand the correct
procedure for sharpening the chain after reading the
instructions that follow, have the saw chain sharp-
ened by an authorized service center or replace
with a recommended low-kickback chain.
