Note: For engine component repair information (e.g. starter motor), refer to the
Yanmar Workshop Manual that is correct for your Groundsmaster model.
1. 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 discharge
more rapidly than if the machine is stored in a location where temperatures
are cool.
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. Unplug charger from electrical outlet before connecting or
disconnecting charger leads to or from battery posts.
Do not remove fill caps (if equipped) while cleaning the battery.
2. Check battery condition weekly or after every 50 hours of operation. Keep
terminals and entire battery case clean because a dirty battery will discharge
slowly.
A. Clean battery by washing entire case with a solution of baking soda and
water. Rinse with clear water.
B. Coat battery posts and cable connectors with battery terminal protector
(Toro Part No. 107−0392) or petroleum jelly to prevent corrosion.
3. Battery cables must be tight on terminals to provide good electrical contact.
Connecting battery cables to the wrong battery post could result in
personal injury and/or damage to the electrical system.
4. If corrosion occurs at terminals, disconnect cables. Always disconnect
negative (−) cable first. Clean clamps and terminals separately. Reconnect
cables with positive (+) cable first. Coat battery posts and cable connectors
with battery terminal protector (Toro Part No. 107−0392) or petroleum jelly
to prevent corrosion.
5. If the battery electrolyte is accessible, check electrolyte level every 25
operating hours and every 30 days if machine is in storage. Maintain cell
level with distilled water. Do not fill cells above the fill line.
