Storage

Store the machine in a cool, clean, dry place.

Storage Safety

Always shut off the machine, wait for all moving
parts to stop, and allow the machine to cool before
adjusting, servicing, cleaning, or storing it.
Preparing the Machine for
Storage
1.
On the last refueling of the year, add fuel
stabilizer (such as Toro Premium Fuel
Treatment) to the fuel as directed on the label.
2.
Dispose of any unused fuel properly. Recycle
it according to local codes or use it in your
automobile.
Important:
Old fuel in the fuel tank is the
leading cause of hard starting. Do not store
the fuel without fuel stabilizer more than
30 days, and do not store stabilized fuel
beyond the duration recommended by the
fuel-stabilizer manufacturer.
3.
Run the machine until the engine shuts off from
running out of fuel.
4.
Start the engine again and allow it to run until
it shuts off. When you can no longer start the
engine, it is sufficiently dry.
5.
Disconnect the wire from the spark plug and
connect the wire to the retaining post (if
equipped).
6.
Remove the spark plug, add 30 ml (1 fl oz) of
engine 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.
Loosely install the spark plug.
8.
Tighten all nuts, bolts, and screws.
Removing the Machine
from Storage
1.
Check and tighten all fasteners.
2.
Remove the spark plug and spin the engine
rapidly by pulling the recoil-start handle to blow
the excess oil from the cylinder.
3.
Install the spark plug and tighten it with a torque
wrench to 20 N∙m (15 ft-lb).
