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 blade OFF).
3. DO NOT allow children or others to ride onmachine or on attachments (even with the bladesOFF). They may fall and be seriously injured.
4. DO NOT allow pre-teenage children to operatemachine.
5. ALLOW only responsible adults & 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.
Tall grass can hide obstacles. Keep away fromditches,
washouts,
culverts,
fencesandprotruding objects.
6. KEEP A SAFE DISTANCE (at least 3 feet) awayfrom edge of ditches and other drop offs. The
machine could turn over if an edge caves in.
7. Always begin forward motion slowly and withcaution.
8. Use weights or a weighted load carrier in accordancewith instructions supplied with a grass catcher. DO
NOT operate machine on slopes exceeding 10
degrees (18% grade) when equipped with grasscatcher.
9. DO NOT put your foot on the ground to try tostabilize the machine.
10. DO NOT operate machine on wet grass. Reduced
traction could cause sliding.
11. DO NOT operate machine under any condition
where traction, steering or stability is doubtful.

PREPARATION
1. Read, understand, and follow instructions andwarnings in this manual and on the machine,engine and attachments. Know the controls andthe proper use of the machine before starting.
2. Only mature, responsible persons shall operate
the machine and only after proper instruction.
3. Data indicates that operators age 60 and above,
are involved in a large percentage of mowerrelated injuries. These operators should evaluate
their ability to operate the mower safely enough toprotect themselves and others from serious injury.
4. Handle fuel with extra care. Fuels are flammableand vapors are explosive. Use only an approved
fuel container. DO NOT remove fuel cap or add
fuel with engine running. Add fuel outdoors onlywith engine stopped and cool. Clean spilled fuelfrom machine. DO NOT smoke.
5. Practice operation of machine with BLADES OFF
to learn controls and develop skills.
6. Check the area to be mowed and remove all
objects such as toys, wire, rocks, limbs and otherobjects that could cause injury if thrown by blade
or interfere with mowing.

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 affect thehandling and the stability of the machine.
1. DO NOT operate machine on slopes exceeding 15
degrees (27% grade).
2. Exercise EXTREME CAUTION on slopes above 10
degrees (18% grade). Turn blades OFF whentraveling uphill. Use a slow speed and avoid
sudden or sharp turns.
3. DO NOT operate machine back and forth acrossface 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 backslowly down the slope.

Shield the positive terminal with terminal coverlocated on battery harness. This prevents metalfrom touching the positive terminal, which could
cause sparks.
4.4.6. BATTERY TESTING
There are two types of battery tests: Unloaded andLoaded. The unloaded test is the procedure that will
be discussed. It’s the 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.

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

1. Using a voltmeter, voltage readings appear
instantly to show the state of charge. Remember tohook the positive lead to the battery’s positive
terminal, and the negative lead to the negative
terminal.
2. A hydrometer measures the specific gravity ofeach cell. The specific gravity tells the degree ofcharge; 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 asmeasured by syringe float hydrometer, digital
voltmeter and five ball hydrometer.

WARNING
DO NOT OVERFILL! DO NOT attempt to charge
battery while installed on the Yard Cruiser. DO NOT
use “BOOST” chargers on the battery.
5. Slow charge the battery at 1 amp for 2 hours tobring the battery to full charge.
6. After charging, check level of electrolyte and add
as needed to bring level to 3/16” above cell plates.
7. Reinstall cell caps.
8. Install battery into power unit. Connect over flow
tube.
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 (-) cable (black) last, to negative terminal(-) on battery using bolt and nut. Apply a small
amount of grease over terminals to prevent
corrosion.
