PROTECTION FOR CHILDRENPROTECTION AGAINST TIPOVERS

Tragic accidents can occur 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 isoperated (even with the blades OFF).
3. DO NOT allow children or others to ride onmachine or on attachments (even with the blade
OFF). They may fall and be seriously injured.
4. DO NOT allow pre-teenage children to operatemachine. Local regulations may restrict the age ofthe operator.
5. ALLOW only adults or responsible teenagers withmature judgment under close adult supervision tooperate machine.
6. DO NOT operate blades in reverse. STOP BLADES.
LOOK and SEE behind and down for children, petsand hazards before and while backing.
7. USE EXTRA CARE when approaching blind
corners, shrubs, trees, or other objects that may
obscure vision.

(Continued From Previous Column)
5. STAY ALERT for holes and other hidden hazards. Tallgrass can hide obstacles. Keep away from ditches,
washouts, culverts, fences and protruding objects.
6. DO NOT operate machine near drop offs, ditches,
embankments, washouts, culverts, fences andprotruding objects. KEEP A SAFE DISTANCE (at least
3 feet) away from edge of ditches and other drop offs.
The machine could turn over if an edge caves in.

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 grasscatchers or other attachments; these and turf
conditions affect the handling and the stability of themachine.
1. DO NOT operate machine on slopes exceeding 15
degrees (27% grade).

4. With cell caps removed, connect battery
charger to battery terminals; RED to positive(+) and BLACK to negative (-) terminal.

WARNING
Shield the positive terminal with terminal coverlocated on battery harness. This prevents metal fromtouching the positive terminal which could over heatbattery and/or battery cable and cause sparks. DO
NOT attempt to charge battery while installed on the
Zero Turning Radius Mower. DO NOT use “BOOST”
chargers on the battery.

IMPORTANT: 3/16” above cell plates is the recommended
level. DO NOT place anything in battery other than specified
electrolyte.

5.7.4. BATTERY TESTING

There are two types of battery tests:
Unloaded and Loaded. The unloaded test is
the procedure that will be discussed. It’s thesimplest 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 ofcharge. Remember to hook the positive
lead to the battery’s positive terminal, andthe negative lead to the negative terminal.
2. A hydrometer measures the specificgravity of each cell. The specific gravity tells
the degree of charge; generally, a specificgravity of about 1.265 to 1.280 indicates fullcharge. A reading of 1.230 to 1.260
indicates the battery should be charged
before testing. The Battery Condition chartshows the charge level as measured bysyringe float hydrometer, digital voltmeterand five ball hydrometer.
