9. The battery should be clean and free of corrosion. Wash the battery top and terminals with a solution of
baking soda and water (1 cup (237 mL) baking soda per 1 gallon (3.8 L) of water). Rinse the solution off
the battery. Do not allow this solution to enter the battery. Be sure the terminals are tight. Let the terminals
dry and then coat them with Battery Terminal Protector Spray (P/N 603 00 00-03).
10. Adjust the tires to the recommended tire pressure. See Vehicle Specifications on page 50.
11. Perform semiannual periodic lubrication. See Periodic Lubrication Schedule on page 32.
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 35 or Figure 36, Page 43).
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 (P/N 603 00 00-03).
4. Gasoline vehicles only: Completely open the fuel shut-off valve (Figure 13, Page 27). Ensure 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 14, Page 27).
5. Place the Forward/Reverse handle in the NEUTRAL position. Crank the engine until fuel is pumped into
the carburetor (gasoline vehicles) and the fuel lines (all vehicles) and the engine starts. Turn the engine
off. See following NOTE.
NOTE: Due to the oil added to the gasoline engine in preparation for storage, the engine may smoke
excessively for a short time when it is run for the first time after storage.
6. Perform the Pre-Operation and Daily Safety Checklist on page 17 and the Performance Inspection on
page 18.
MAINTENANCE
See General Warnings on page 8.
To ensure trouble-free vehicle performance, follow an established preventive maintenance program. Regular
and consistent maintenance can prevent vehicle downtime and expensive repairs. Use the Pre-Operation
and Daily Safety Checklist on page 17, the Performance Inspection on page 18, and the following Periodic
Service Schedule and Periodic Lubrication Schedule to keep the vehicle in proper working condition.
Any vehicle not functioning correctly should not be used until it is properly repaired. This will prevent further
damage to the vehicle and help prevent injury to occupants resulting from unsafe conditions.
Contact your local Husqvarna dealer/distributor for repairs and semiannual and annual periodic service.
