Service and Repairs

NOTE: For more component repair information, see the Briggs and Stratton Vanguard Service and Repair Manual for 4–Cycle, V–Twin Cylinder, OHV Engines.

Battery Storage

If the machine will be stored for more than 30 days

1.Remove the battery and charge it fully (see Battery Service).

2.Either store battery on a shelf or on the machine.

3.Leave cables disconnected if the battery is stored on the machine.

4.Store battery in a cool atmosphere to avoid quick deterioration of the battery charge.

5.To help prevent the battery from freezing, make sure it is fully charged (see Battery Service).

Battery Care

1.Battery electrolyte level must be properly main- tained. The top of the battery must be kept clean. lf the machine is stored in a location where temperatures are extremely high, the battery will run down more rapidly than if the machine is stored in a location where temper- atures are cool.

WARNING

Wear safety goggles and rubber gloves when working with electrolyte. Charge battery in a well ventilated place so gasses produced while charging can dissipate. Since the gases are explosive, keep open flames and electrical sparks away from the battery; do not smoke. Nausea may result if the gases are inhaled. Un- plug charger from electrical outlet before con- necting or disconnecting charger leads to or from battery posts.

2.Keep top of battery clean by washing periodically with a brush dipped in ammonia or bicarbonate of soda solution. Flush top surface with water after cleaning. Do not remove the fill cap while cleaning.

3.Battery cables must be tight on terminals to provide good electrical contact.

WARNING

Connecting cables to the wrong post could re- sult in personal injury and/or damage to the electrical system.

4.If corrosion occurs at terminals, disconnect cables. Always disconnect negative (–) cable first. Scrape clamps and terminals separately. Reconnect cables with positive (+) cable first. Coat terminals with petro- leum jelly.

5.Check electrolyte level every 25 operating hours, and every 30 days if machine is in storage.

6.Maintain cell level with distilled or demineralized water. Do not fill cells above the fill line.
