Maintenance
5. To protect the engine, remove spark plug and pour 1/2 ounce (14.2 mL) of SAE 10 weight oil into the engine
through the spark plug hole. Rotate engine crankshaft by hand several times, then install the spark plug and
tighten to 20 ft-lb (27 N·m).
6. Adjust tires to recommended tire pressure. See Vehicle Specifications on page 48.
7. Perform semiannual periodic lubrication. See Periodic Lubrication Schedules on page 34.
8. Thoroughly clean front body, rear body, seats, engine compartment, and underside of vehicle.
9. Do not engage the park brake. Chock the wheels to prevent the vehicle from rolling.
RETURNING THE STORED GASOLINE VEHICLE TO SERVICE
1. Restore fuel system to operation (Figure 31).
1.1. Remove plug from fuel tank vent.
1.2. Connect vent tube to fuel tank vent.
2. Connect battery cables, positive (+) cable first, and tighten terminals to 144 in-lb (16 N·m).
3. Completely open the fuel shut-off valve (Figure 17). Make sure 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.
4. Place the Forward/Reverse handle in the NEUTRAL position. Crank the engine until fuel is pumped into the
carburetor and fuel lines and the engine starts. Turn the engine off. See following NOTE.
NOTE: Due to the oil added to the engine in preparation for storage, engine may smoke excessively for a short
time when it is run for the first time after storage.
5. Adjust tires to recommended tire pressure. See Vehicle Specifications on page 48.
6. Perform the Pre-Operation and Daily Safety Checklist on page 20.
MAINTENANCE
See General Warnings on page 10.
To ensure trouble-free vehicle performance, it is very important to follow an established preventive maintenance
program. Regular and consistent vehicle maintenance can prevent vehicle downtime and expensive repairs that can
result from neglect. Use the Pre-Operation and Daily Safety Checklist on page 20 and the following Periodic Service
Schedules and Periodic Lubrication Schedules to keep the vehicle in proper working condition.
Any vehicle not functioning correctly should be removed from use 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 distributor/dealer to perform all repairs and semiannual and annual periodic service.
WARNING
• If any problems are found during scheduled inspection or service, do not operate the vehicle until
repairs are made. Failure to make necessary repairs could result in fire, property damage, severe
personal injury, or death.
• Only trained technicians should service or repair the vehicle or battery charger. Anyone doing even
simple repairs or service should have knowledge and experience in electrical and mechanical repair.
The appropriate instructions must be used when performing maintenance, service, or accessory
installation.
