5. Install the new blade (turn the blade bolt clockwise)
and all mounting hardware.
Important: Position the curved ends of the
blade to point toward the machine housing.
6. Use a torque wrench to tighten the blade bolt to
25 N-m (18 ft-lb).
Important: A bolt torqued to 25 N-m (18 ft-lb) is
very tight. While holding the blade with a block
of wood, put your weight behind the ratchet or
wrench and tighten the bolt securely. This bolt
is very difficult to overtighten.
Cleaning the Machine

Preparing the Machine for
Storage
WARNING
Gasoline vapors can explode.
• Do not store gasoline more than 30 days.
• Do not store the machine in an enclosure near
an open flame.
• Allow the engine to cool before storing it.
1. On the last refueling of the year, add fuel stabilizer
to the fuel as directed by the engine manufacturer.
2. Run the machine until the engine stops from running
out of fuel.
3. Prime the engine and start it again.
4. Allow the engine to run until it stops. When you can
no longer start the engine, it is sufficiently dry.
5. Disconnect the wire from the spark plug.
6. Remove the spark plug, add 30 ml (1 oz.) of oil
through the spark plug hole, and pull the starter rope
slowly several times to distribute oil throughout the
cylinder to prevent cylinder corrosion during the
off-season.
7. Install the spark plug and tighten it with a torque
wrench to 20 N-m (15 ft-lb).
8. Tighten all nuts, bolts, and screws.
