Storing Safety
CAUTION: Avoid injury! Fuel vapors are explosive and
ammable.
Engine exhaust fumes contain carbon monoxide and cause
serious illness or death:
● Run the engine only long enough to move the machine to
or from storage.
● If a machine is stored before allowing it to cool, machine
res and structure res can occur. Fires can occur if
debris is not removed from around the engine and
muer, or if stored near combustible materials.
● Do not store vehicle with fuel in the tank inside a building
where fumes reach an open ame or spark.
● Allow the engine to cool before storing the machine in
any enclosure.

Preparing Machine for Storage
1. Repair any worn or damaged parts. Replace parts if necessary.
Tighten loose hardware.
2. To prevent rust, repair scratched or chipped metal surfaces.
3. Remove grass and debris from machine.
4. Clean under the rotary deck and remove grass and debris from
inside chute and bagger, if applicable.
5. Wash the machine and apply wax to metal and plastic surfaces.
6. To dry belts and pulleys, run machine for ve minutes.
7. To prevent rust, apply light coat of engine oil on pivot and wear
points.
8. 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”:
1. 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.
2. Turn on engine and allow to run until it runs out of fuel.
3. For machines equipped with key switch, turn key to o position.
IMPORTANT: Avoid damage! Stale fuel can produce varnish and
plug carburetor or injector components and aect engine
performance.
● Add fuel conditioner or stabilizer to fresh fuel before
lling tank.
4. Mix fresh fuel and fuel stabilizer in separate container. Follow
stabilizer instructions for mixing.
5. Fill fuel tank with stabilized fuel.
6. Run engine for a few minutes to allow fuel mixture to circulate
through carburetor on gas engine or fuel injectors on diesel engine.
Engine:
Engine storage procedure should be used when vehicle is not to be
used for longer than 60 days.
1. Change engine oil and lter.
2. Service air lter if necessary.
3. Clean debris from engine air intake screen.
4. On gas engines:
● Remove spark plugs. Put 30 mL (1 oz) of clean engine oil in
cylinders.
● Install spark plugs, but do not connect spark plug wires.
● Crank the engine 5 or 6 times to allow oil to be distributed.
5. Clean the engine and engine compartment.
6. Remove battery.
7. Clean the battery and battery posts. Check the electrolyte level if
your battery is not maintenance free.
8. Close fuel shuto valve if your machine is equipped.
9. Store the battery in a cool, dry place where it will not freeze.
NOTE: The stored battery should be recharged every 90 days.
10. Charge the battery.
IMPORTANT: Avoid damage! Prolonged exposure to sunlight
could damage surfaces. Store machine inside or use a
cover if stored outside.
11. Store the vehicle in a dry, protected place. If vehicle is stored
outside, put a waterproof cover over it.

Removing Machine From Storage
1. Check tire pressure.
2. Check engine oil level.
3. Check battery electrolyte level if your battery is not maintenance
free. Charge battery if necessary.
4. Install battery.
5. On gas engines: check spark plug gap. Install and tighten plugs to
specied torque.
6. Lubricate all grease points.
7. Open fuel shut-o valve if your machine is equipped.
8. Run the engine 5 minutes without the mower or any attachments
running to allow oil to be distributed throughout engine.
9. Be sure all shields and guards or deectors are in place.
