Preparing Machine for Storage

Repair any worn or damaged parts. Replace parts if necessary.
Tighten loose hardware.

Repair scratched or chipped metal surfaces to prevent rust.

Remove grass and debris from machine.

Clean under the deck and remove grass and debris from inside chute
and bagger.

Wash the machine and apply wax to metal and plastic surfaces.

Run machine for five minutes to dry belts and pulleys.

Apply light coat of engine oil to pivot and wear points to prevent rust.

Lubricate grease points and check tire pressure.

Preparing Fuel and Engine For Storage

Fuel:

If you have been using “Stabilized Fuel,” add stabilized fuel to tank until
the tank is full.

NOTE: Filling the fuel tank reduces the amount of air in the fuel tank and

helps reduce deterioration of fuel.

If you are not using “Stabilized Fuel:”

Park machine safely in a well-ventilated area. (See Parking Safely in
the SAFETY section.)

NOTE: Try to anticipate the last time the machine will be used for the

season so very little fuel is left in the fuel tank.

Turn on engine and allow to run until it runs out of fuel.

For machines equipped with key switch, turn key to off position.

IMPORTANT: Stale fuel can produce varnish and plug carburetor or

injector components and affect engine performance.
