Maintenance - Husqvarna HUV4420-D Owner's Manual

All vehicles:
8. Disconnect the battery cables, negative (–) cable first. See WARNING "To avoid unintentionally start-
ing..." on page 11.
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 (P/N 603 00 00-03).
10. Adjust the tires to the recommended tire pressure. See Vehicle Specifications on page 47.
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 32, Page 42 or Figure 33, Page 42).
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 20 ft-lb (27.1 N·m). Coat
terminals with Battery Terminal Protector Spray (P/N 603 00 00-03).
4. Gasoline vehicles only: Completely open the fuel shut-off valve (Figure 11). 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 12).
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 and the engine starts. Turn the engine off. See fol-
lowing NOTE.
NOTE: Due to the oil added to the 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 19.

MAINTENANCE

See General Warnings on page 10.
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 19 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 avoid the possibility of injury due to unsafe conditions.
Contact your local Husqvarna dealer/distributor for repairs and semiannual and annual periodic service.
