67Maintenance Instructions CHECKING/SERVICINGBatteryNOTE: For initial battery service during setup, referto Battery Service in Assembly Instructions.IMPORTANT: Make sure battery is securely mount-ed in the frame. A loose battery may cause damageto the case resulting in acid leakage and severe dam-age to the machine. A hazard may be created bydamage to critical working parts and safety systems.CAUTIONImportant Battery Service, Installation, andChanging Tips:• Do not allow the battery cables to touchopposing terminals. When connecting bat-tery cables attach the positive (+) cable topositive (+) battery terminal first, followedby negative (-) cable to negative (-) batteryterminal.• Never start the engine when the cablesare loose or poorly connected to the bat-tery terminals.• Never disconnect battery while engineis running.• Never use a quick battery charger tostart the engine.• Never “jump start” the engine using an-other source. Electricity fluctuations candamage the ECU (Electronic Control Unit).• Always disconnect negative (-) batterycable lead before charging battery, andalso unplug harness from ECU before per-forming any welding on equipment.Electrolyte LevelThe battery electrolyte level should be checked af-ter every 25 hours of operation. To check electro-lyte level:1. Remove battery cell filler caps.2. Check the electrolyte level. If the level is belowthe bottom of the vent well, fill with drinking wa-ter to the bottom of the vent wells [1/4 to 1/2 in.(6 to 13 mm) above the plates].3. Replace filler caps.IMPORTANT: DO NOT overfill the battery. Electro-lyte will overflow through the vented caps onto partsof the machine and WILL result in severe corrosion.Cleaning the TerminalsIf battery terminals are corroded, remove batteryfrom the mower. Using a wire brush, remove corro-sion with a solution of one part baking soda andfour parts water. Rinse with clean water. Coat theterminals with petroleum jelly or terminal protectorspray to retard further corrosion.Charging the BatteryDANGERBATTERIES PRODUCE EXPLOSIVE GASES• Charge the battery in a well-ventilatedarea, so that gases produced while charg-ing can dissipate.• Keep sparks, flames, and smoking ma-terials away from the battery at all times.• Make sure the battery cap vents areopen (check manifold vent on each cap).• Make sure the battery charger is un-plugged before connecting or discon-necting cables to the battery.Check the battery charge by measuring the specificgravity of electrolyte; if specific gravity is less than1.225, the battery will need to be charged as follows:IMPORTANT: Always disconnect the negative (-)battery terminal before charging. Failure to do socan result in damage to the ECU.1. Charge the battery at 15 amps for 10 minutes.DO NOT exceed 20 amps maximum recom-mended charging rate. Charge until specificgravity is at least 1.250. Total charging timeshould not exceed one (1) hour.2. After charging the battery, use distilled water toadjust the electrolyte level to the bottom of thevent wells [1/4 to 1/2 in. (6 to 13 mm) above theplates].
