All vehicles:
8. Disconnect the battery cables, negative (–) cable first. See WARNING “To avoid unintentionally start-
ing...” in Section 1 – Safety on page 1-2.
9. Batteries should be clean and free of corrosion. Wash tops and terminals of batteries with a solution of
baking soda and water (1 cup (237 mL) baking soda per 1 gallon (3.8 L) of water). Rinse solution off bat-
teries. Do not allow this solution to enter the batteries. Be sure terminals are tight. Let the terminals dry
and then coat them with Battery Terminal Protector Spray (Husqvarna 603 00 00-03).
10. Adjust the tires to the recommended tire pressure. See Section 8 – Wheels and Tires.
11. Perform semiannual periodic lubrication. See Periodic Lubrication Schedule on page 10-4.
12. Thoroughly clean the front body, rear body, seats, cargo bed, engine compartment, and underside of
vehicle.
13. Do not engage the park brake. Chock the wheels to prevent the vehicle from rolling.
RETURNING THE STORED VEHICLE TO SERVICE
1. Make sure the key switch is in the OFF position and the Forward/Reverse handle is in the NEUTRAL
position. Chock the wheels.
2. Restore the fuel system to operation (Figure 3-2, Page 3-3 or Figure 3-3, Page 3-3) .
2.1. Remove the plug from the fuel tank vent.
2.2. Connect the vent tube to the fuel tank vent.
3. Connect the battery cables, positive (+) cable first, and tighten the terminals to 12 ft-lb (16 N·m). Coat ter-
minals with Battery Terminal Protector Spray (Husqvarna 603 00 00-03).
4. Gasoline vehicles only: Completely open the fuel shut-off valve (Figure 3-4, Page 3-4) . Ensure that
the valve is fully open. A partially closed fuel shut-off valve combined with the use of the choke can result
in a fouled spark plug and engine failure
(Figure 3-6, Page 3-4) .
