CHAIN REPLACEMENT
WARNING: Wear protective
gloves when handling chain. The chain
is sharp and can cut you even when it is
not moving.
It is normal for a new chain to stretch dur-
ing the first 15 minutes of operation. You
should recheck your chain tension fre-
quently and adjust the chain tension as
required. See CHECK CHAIN TENSION
section.
Replace the old chain when it becomes
worn or damaged.
