Raise the tines, stop the machine, stop the engine, and
disconnect the spark-plug wire.
2.
Raise the front of the machine to gain access to the
chain, and block it in place.
CAUTION
If you do not securely block up the front of the
machine, the machine could fall on you during
service, injuring you.
Ensure that you place a jack stand or block
under the front of the machine to hold it up
securely.
Important:
Do not raise the rear of the machine.
Raising the rear of the machine will cause the
engine to flood and the air cleaner to be fouled
with gasoline.
