PROTECTION FOR CHILDREN

PROTECTION 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.

(Continued From Previous Column)
4. AVOID uphill starts. If machine stops going uphill
or tires lose traction, turn blade OFF and back
slowly down the slope.
5. STAY ALERT for holes and other hidden hazards.
Tall grass can hide obstacles. Keep away from
ditches,
washouts,
culverts,
fences
and
protruding objects.
6. KEEP A SAFE DISTANCE (at least 3 feet) away
from edge of ditches and other drop offs. The
mower could turn over if an edge caves in.
7. Always begin forward motion in the #1 speed
position.
8. Use weights or a weighted load carrier in accordance
with instructions supplied with a grass catcher. DO
NOT operate machine on slopes exceeding 10
degrees (18% grade) when equipped with grass
catcher.
9. DO NOT put your foot on the ground to try to
stabilize the machine.
10. DO NOT mow on wet grass. Reduced traction
could cause sliding.
11. DO NOT mow under any condition where traction,
steering or stability is doubtful without first test
driving over the terrain with blade OFF.

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 other passengers to ride
on machine or on attachments (even with the
blade 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. BE SURE the area is clear of others before
mowing and turn machine OFF if anyone enters
the area.
7. DO NOT operate blades in reverse. STOP BLADES.
Look and See behind and down for children, pets
and hazards before and while backing.
8. USE EXTRA CARE when approaching blind
corners, shrubs, trees, or other objects that may
obscure vision.

PREPARATION
1. Read this manual, get to know where all controls
are located and practice how to use them before
starting for the first time, and at the beginning of
each season. Read and follow Warnings and
Instructions on engine and machine. Read and
follow operator’s manual and instructions
furnished with attachments.
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 to
protect themselves and others from serious injury.

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
it, DO NOT mow it. Use extra care with grass catchers
or other attachments; these can change 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 blade OFF when
traveling uphill. Use first speed and avoid sudden
or sharp turns.
3. DO NOT mow back and forth across face of
slopes. Mow up and down.

4. Handle fuel with extra care. Fuels are flammable
and vapors are explosive. Use only an approved
fuel container. Never remove fuel cap or add fuel
with engine running. Add fuel outdoors only with
engine stopped and cool. Clean spilled fuel from
machine. DO NOT smoke.
5. Practice operation of machine with BLADE 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 other
objects that could cause injury if thrown by blade
or interfere with mowing.
7. Keep people and pets a safe distance from
machine.
8. Check shields, deflectors, switches, blade controls
and other safety devices frequently for proper
operation and location.
9. Make sure all safety decals are clearly legible.
Replace if damaged.
10. Protect yourself when mowing and wear safety
glasses, long pants and substantial footwear.
11. Know how to STOP blade and engine quickly in
preparation for emergencies.
12. Use extra care when loading or unloading the
machine into a trailer or truck.
13. Check grass catcher components frequently for
signs of wear or deterioration and replace as
needed to prevent injury from thrown objects
going through weak or worn spots.

(Continued From Previous Column)
12. Mow only in daylight or with good artificial light.
13. Move joystick (if equipped) SLOWLY to
maintain control during speed and directional
changes.
14. Exercise CAUTION when pulling loads. Limit
loads to those you can safely control and attach
loads to hitch plate as specified with SNAPPER
attachment instructions.

MAINTENANCE
1. Never store machine or fuel container inside
where fumes may reach an open flame, spark or
pilot light such as in a water heater, furnace,
clothes dryer or other gas appliance. Allow
engine to cool before storing machine in an
enclosure. Store fuel container out of the reach
of children in a well ventilated, unoccupied
building.
2. Keep engine free of grass, leaves or excess
grease to reduce fire hazard and engine
overheating.
3. When draining fuel tank, drain fuel into an
approved container outdoors and away from
open flame.
4. Check brakes frequently; adjust, repair or
replace as needed.
5. Keep all bolts, nuts and screws properly tight.
Check that all cotter pins are in proper position.

WARNING

WARNING

The electrolyte (acid) produces a highly 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 immediately after
having eye or skin contact with 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. Never attempt to
charge battery while installed on the YARD CRUISER.
Never use “BOOST” chargers on the battery.

DO NOT OVERFILL! Never attempt to charge battery
while installed on the Yard Cruiser. Never use
“BOOST” chargers on the battery.
5. Slow 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 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.

4.4.3. BATTERY SERVICE
1. Remove battery. See Section on 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 of which can also be visualized
through the plastic battery case.
4. With cell caps removed, 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, Part Number 6-0753.

WARNING
Shield the positive terminal with terminal cover
located on battery harness. This prevents metal
from touching the positive terminal which could
cause sparks.
4.4.6. BATTERY TESTING
There are two types of battery tests: Unloaded and
Loaded. 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.

4.4.4. BATTERY STORAGE
If YARD CRUISER is to be stored out of season on
its rear bumper, it is recommended the battery be
removed, charged and stored.
1. Remove battery. (See 4.4.1., Battery Removal)
2. Perform battery service.
3. Bring battery to full charge, if required.
4. Store battery in an area away from the YARD
CRUISER on a wood surface. DO NOT STORE
BATTERY ON A CONCRETE SURFACE.

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.

4.4.5. NEW BATTERY PREPARATION
1. Remove battery from carton.
2. Place battery in a well ventilated area on a level
non-concrete surface.
3. Remove battery cell caps. Fill cells as required
with electrolyte (purchased separately) to proper
level. Fill to 3/16” above cell plates. 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 (-) terminal.

(Continued on Next Page)

IMPORTANT: 3/16” above cell plates is the recommended
level. However do not try to measure this dimension. Never
place anything in battery other than specified electrolyte.
