PROTECTION FOR CHILDREN

Tragic accidents can occu r if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

1. KEEP children out of the mowing area and under the watchful care of a responsible adult.

2. DO NOT allow children in yard when machine is operated (even with the blade OFF).

3. DO NOT allow children or others to ride on machine or on attachments (even with the blades OFF). They may fall and be seriously injured.

4. DO NOT allow pre-teenage children to operate machine.

5. ALLOW only responsible adults & teenagers with mature judgment under close adult supervision to operate machine.

6. DO NOT operate blades in reverse. STO P BLADES. LOOK and SEE behind an d down for children, pets and hazards before and while backing.

7. USE EXTRA CARE when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

PROTECTION AGAINST TIPOVERS

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra CAUTION. If you cannot back up the slope or if you feel uneasy on the slope, DO NOT mow it. Use extra care with grass catchers or other attachments; these affect the handling and the stability of the machine.

1. DO NOT operate machine on slopes exceeding 15 degrees (27% grade).

2. Exercise EXTREME CAUTION on slop es above 10 degrees (18% grade). Turn blades OFF when traveling uphill. Use a slow speed and avoid sudden or sharp turns.

3. DO NOT operate machine back and forth across face of slopes. Operate up and down. Practice on slopes with blades off.

4. AVOID uphill starts. If machine stops going uphill or tires lose traction, turn blades OFF and back slowly down the slope.

PROTECTION AGAINST TIPOVERS

WARNING

The electrolyte (acid) produces a h ighly explosive gas. Keep all sparks, flame and fire away from area when charging battery or when handling electrolyte or battery. Electrolyte (acid) is a highly corrosive liquid. Wear eye protection. Wash affected areas immed iately after having eye or skin contact w ith electrolyte (acid). Battery acid is corrosive. Rinse empty acid containers with water and mutilate before discarding. If acid is spilled on battery, bench, or clothing, etc., flush with clear water and neutralize with baking soda.

WARNING

DO NOT attempt to charge battery while installed on the Riding Mower. DO NOT use “BOOST” chargers on the battery. DO NOT OVERFILL!

4.8.3. Battery Service

1. Remove battery. Refer to Section “BATTERY

REMOVAL”.

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 r emoved, connect battery charger to battery terminals. Red to positive (+) terminal and black to negative (-) terminal.

5. Slow 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.

4.8.4. Battery Storage

If machine is to be stored out of season, it is recommended the battery be removed, charged and stored. If the machine is stored out of season on its rear bumper, the battery must be removed, charged and stored.

4.8.5. Battery Testing

There are two types of battery tests: Unloaded and Loaded. The unloaded test is the proc edur e that will be discussed. It’s the sim plest and most comm only 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. Measure the battery voltage and com pare to the voltages listed in the “BATTERY CONDIT IO N CHART” in this manual to determine condition of battery.

2. A hydrometer measures the specific gravity of the electrolytes in 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 “Battery Condition Chart” included in this manual shows the charge level as measured by syringe float hydrometer, digital voltmeter and five ball hydrometer.
