How To Store The Battery
If the unit is to be stored out of season, it is recommended
the battery be removed, charged and stored.
1. Remove the battery. Refer to "How To Remove The
Battery".
2. Charge the battery. Refer to "How To Charge The
Battery".
3. Store the battery in an area away from the unit on a
wood surface. DO NOT STORE THE BATTERY ON A
CONCRETE SURFACE.
Storage
1. Thoroughly clean the unit by removing all grass clippings
and debris.
2. Perform maintenance and lubrication as required.
3. Drain the fuel from the fuel tank (unless using a fuel sta-
bilizer - Refer to "Fuel System").
4. Start the engine and allow it to run until the engine runs
out of fuel. This allows the carburetor and fuel system to
remain clean during storage.
5. Remove and store the battery. Refer to "How To Store
The Battery".

Fuel System

Fuel can become stale when stored over 30 days. Stale
fuel causes acid and gum deposits to form in the fuel sys-
tem or on essential carburetor parts. To keep fuel fresh, use
Briggs & Stratton Advanced Formula Fuel Treatment &
Stabilizer, available wherever Briggs & Stratton genuine ser-
vice parts are sold.
There is no need to drain gasoline from the engine if a fuel
stabilizer is added according to instructions. Run the engine
for two (2) minutes to circulate the stabilizer throughout the
fuel system before storage.
If gasoline in the engine has not been treated with a fuel sta-
bilizer, it must be drained into an approved container. Run the
engine until it stops from lack of fuel. The use of a fuel sta-
bilizer in the storage container is recommended to maintain
freshness.

(B) Wear limit (notch starts);
(C) Dangerous condition - do not use on mower! Replace
with new blade. Contact your authorized dealer.

How To Level The Mower Deck
WARNING
Wear heavy leather gloves when handling or working
around cutting blades. Blades are extremely sharp and can
cause severe injury.
Side-To-Side Leveling
Before making deck leveling adjustments, check the tire
pressure. Refer to "How To Check Tire Pressure". If tires are
properly inflated and mowing is still uneven, adjust side-to-
side deck leveling.
1. Place the unit on a smooth level surface.
2. Turn the engine off and remove the key. Remove the
spark plug wire from the spark plug and secure the wire
away from the plug.
3. Raise the mower deck to the highest cutting position.
4. Place a piece of angle iron, pipe, or similar object under
the rear center of the deck.
5. Lower the mower deck until the rear of the deck is sup-
ported by the object placed under it in the previous step.
(The rear hanger rods (A, Figure 36) should be loose.)
