4.5.BATTERY SERVICE
4.5.1. NEW BATTERY PREPARATION
1.Remove battery from carton.
2.Place battery in a well ventilated area on a level
3.Remove battery cell caps. Fill cells as required with electrolyte (supplied with battery) to proper level. Filling battery with electrolyte will bring the battery to 80% charged state.
4.With cell caps removed, connect battery charger to battery terminals; RED to positive (+) and BLACK to negative
IMPORTANT: Never place anything in battery other than specified electrolyte.
5.Stow charge the battery at 1 amp for 2 hours to bring the battery to full charge.
6.After charging, check level of electrolyte and add as needed to bring to proper fluid level.
7.Reinstall cell caps.
8.Install battery into power unit.
9.Connect positive (+) cable (red) first, from wiring harness to the positive terminal (+) on battery using bolt and nut provided in hardware bag. Connect negative

clear water and neutralize with baking soda. Never attempt to charge battery while installed on the walk behind. Never use "BOOST" chargers on the battery.
4.5.2.BATTERY SERVICE
1.Remove battery.
2.Place battery in a well ventilated area on a level surface.
3.Using distilled water, refill cells as required to cover cell plates.
4.With cell caps removed, connect battery charger to battery terminals. Red to positive (+) terminal and black to negative
5.Stow charge battery at 1 amp for 10 hours.
6.If battery will not accept charge or is partially charged after 10 hours of charging at 1 amp, replace with new battery.
4.5.3.BATTERY STORAGE
If Walk Behind is to be stored out of season on its rear bumper, it is recommended the battery be removed, charged and stored.
1.Remove battery.
2.Perform battery service.
3.Bring battery to full charge, if required.
4.Store battery in an area away from the Walk Behind on a wood surface. DO NOT STORE BATTERY ON A CONCRETE SURFACE.
4.5.4.BATTERY TESTING
There are two types of battery tests: Unloaded and Loaded. The unloaded test is the procedure that will be discussed. It'sthe simplest and most commonly used. An unloaded test is made on a battery without discharging current. To perform unloaded testing, check charge condition using either a hydrometer or voltmeter.
1.Using a voltmeter, voltage readings appear instantly to show the state of charge. Remember to hook the positive lead to the battery's positive terminal, and the negative lead to the negative terminal.
2.A hydrometer measures the specific gravity of each cell. The specific gravity tells the degree of charge; generally, a specific gravity of about 1.265 to 1.280 indicates full charge. A reading of 1.230 to 1.260 indicates the battery should be charged. The chart on the next page shows the charge level as measured by syringe float hydrometer, digital voltmeter and five ball hydrometer.
