Assembly Instructions18IMPORTANT: Obtain and use only batterygrade sulfuric acid electrolyte with a 1.265 spe-cific gravity to activate the battery. DO NOT usewater or any other liquid during initial activation.2. Remove the filler caps and carefully fill each celluntil the electrolyte is just above the plates.3. After the battery is filled with electrolyte, replacethe filler caps and charge the battery. Refer toBattery Charging.Battery ChargingDANGERBATTERIES PRODUCE EXPLOSIVE GASES• Charge the battery in a well-ventilatedarea, so that gases produced while charg-ing can dissipate.• Keep sparks, flames, and smoking materials away from the battery at all times.• Make sure the battery cap vents areopen after the battery is filled with acid(check manifold vent on each cap).• Make sure the battery charger is un-plugged before connecting or disconnect-ing cables to the battery.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, adjust the electrolytelevel to the bottom of the vent wells [1/4 to 1/2 in.(6 to 13 mm) above the plates].IMPORTANT: DO NOT overfill the battery.Electrolyte will overflow through the vented capsonto parts of the machine and WILL result in se-vere corrosion.3. Install battery.Battery InstallationIMPORTANT: Make sure battery is securely mount-ed in the frame. A loose battery may cause damageto the case resulting in acid leakage and severedamage to the machine. A hazard may be createdby damage to critical working parts and safety sys-tems.Install the battery in the mower as shown in BatteryInstallation photo. Connect the positive (+) first andthen the negative (-) cable to the proper battery ter-minal [red cable and boot connects to the Posi-tive (+) terminal]. Slide the rubber boot up and overthe battery post, making sure it covers the post com-pletely to prevent an electrical short.WARNINGMake sure the battery cap vents are open.Improper venting of the battery COULDcause a battery explosion.Battery ClampSecured byWing Nut(s)Battery Installation
