7.7 BATTERY
A. Checking Electrolyte Level and Cleaning Battery
After every 40 hours of operation or weekly, whichever occurs first, check the electrolyte level in the battery and clean the battery and connections. Dirt and fluid on the top of the battery can cause the battery to discharge.
Corrosion of the battery terminals or loose connections will cause poor battery performance.
WARNING:
1.Loosen the two plastic wing nuts and then remove the battery cover.
2.Remove the battery cell caps. Visually inspect electrolyte level in the cells. If electrolyte is
below the bottom of vent well, fill with clean distilled water to the bottom of vent wells (1/4 to 1/2 inch above the plates). Install the battery cell caps.
Do not overfill the battery. Electrolyte will overflow through the vent tube onto parts of the machine, resulting in severe corrosion.
3.Clean the cable ends and battery posts with steel wool. Use a solution of baking soda and water to clean the battery. Do not allow the solution to enter the battery cells.
4.Tighten the cable connections securely and apply a light coat of silicone dielectric grease to the terminal connections to prevent corrosion.
5.Install the battery cover.
WARNING:
Electric storage battery fluid contains sulfuric acid which is POISON and can cause SEVERE CHEMICAL BURNS. Avoid contact of fluid with eyes, skin, or clothing. Use proper protective gear when handling batteries. DO NOT tip any battery beyond 45° angle in any direction. If fluid contact does occur, follow first aid suggestions below.
BATTERY ELECTROLYTE FIRST AID
EXTERNAL CONTACT — Flush with water.
EYES — Flush with water for at least 15 minutes and get medical attention immediately.
INTERNAL — Drink large quantities of water. Follow with Milk Of Magnesia, beaten egg,
or vegetable oil. Get medical attention immediately. In case of internal contact, DO NOT give fluids that would induce vomiting.
B. Charging the Battery
Refer to the battery charger’s manual for specific instructions.
Under normal conditions the engine’s alternator will have no problem keeping a charge on the battery. If the battery has been completely discharged for a long period of time, the alternator may not be able to recharge the battery, and a battery charger will be required.
DO NOT charge a frozen battery. It may explode and cause injury. Let the battery warm before attaching a charger.
Whenever possible, remove the battery from the mower before charging and make sure the electrolyte covers the plates in all cells.
