Battery Care

Electrical System: Service and Repairs
1. The battery-electrolyte level must be properly maintained. The top of the
battery must be kept clean. If the machine is stored in a location where the
temperatures are extremely high, the battery will discharge more rapidly than
if the machine is stored in a location where the temperatures are cool.
The gases are explosive; also, they can cause nausea.
• Wear safety goggles and rubber gloves when working with
electrolyte. Charge the battery in a well ventilated place so that
the gasses produced while charging can dissipate.
• Keep open flames and electrical sparks away from the battery;
do not smoke.
• Disconnect the charger from the electrical outlet before
connecting or disconnecting charger leads to or from the
battery posts.
2. Clean the top of the battery by washing at the intervals with a brush dipped
in ammonia or bicarbonate of soda solution. Flush the top surface with
water after cleaning.
Do not remove fill caps while cleaning.
3. Tighten the battery cables on the battery terminals to provide a good
electrical contact.
Connecting the cables to the wrong battery post could result in
personal injury and/or damage to the electrical system.
Ensure that the cables are properly connected to the correct battery
posts before operating the machine.
4. If corrosion occurs at the battery terminals, disconnect the cables. Always
disconnect the negative (-) cable first. Clean the cable clamps and terminals
separately. Connect the cables with the positive (+) cable first. Apply a layer
of battery terminal protector (Toro Part No. 107-0392) or a light coat of
grease to the terminals to reduce corrosion after you make the connections.
5. Check the battery-electrolyte level every 25 operating hours and every 30
days if machine is in storage.
6. Maintain the cell level with the distilled or demineralized water.
Note: Do not fill the cells above the fill line.
