PROTECTION FOR CHILDREN
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 is
operated and turn machine OFF if anyone enters
the area.
3. DO NOT allow pre-teenage children to operate

necessary. LOOK and SEE behind and down for
children, pets and hazards before and while
backing.
6. USE EXTRA CARE when approaching blind
corners, shrubs, trees, or other objects that may
obscure vision.
SLOPE OPERATION
1. Slopes are a major factor related to slip and fall
accidents, which can result in severe injury. All
slopes require extra caution. If you feel uneasy on
a slope, DO NOT mow it.
2. Mow across slopes, never up-and-dow n. Exercise
extreme CAUTION when changing directions on
slopes. DO NOT mow steep slopes or other areas
where stability or traction is in doubt.
3. Use extra care with grass catchers or other
attachments; these affect the handling and the
stability of the machine.

PREPARATION
(Continued From Previous Column)
3. Data indicates that operators age 60 and above, are
involved in a large percentage of mower-related
injuries. These operators should evaluate their
ability to operate the mower safely enough to
protect themselves and others from serious injury.
4. Handle fuel with extra care. Fuels are flammable
and vapors are explosive. Use only an approved
fuel container. DO NOT remove fuel cap or add fuel
with engine running. Add fuel outdoors only with
engine stopped and cool. Clean spilled fuel and oil
from machine. DO NOT smoke.
5. 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. Also note the location of
holes, stumps, and other possible hazards.

truck or trailer bed with a plastic liner. Always place
the containers on the ground away from the vehicle
before filling.
7. Remove gas-powered equipment from the vehicle or
trailer and refuel it on the ground. If this is not
possible, then refuel equipment using a portable
container, rather than a gasoline dispenser nozzle.
8. DO NOT start gas powered equipment in enclosed
vehicles or trailers.
9. Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until fueling is
complete. DO NOT use a nozzle lock-open device
10. If fuel is spilled on clothing, change clothing
immediately.
11. DO NOT overfill a fuel tank. Replace fuel cap and
tighten securely.
OPERATION
1. DO NOT put hands or feet near or under rotating
parts. Keep clear of discharge area while engine is
running.
2. STOP engine when crossing gravel drives, walks, or
roads, and under any conditions where thrown
objects might be a hazard.
3. Mow only in daylight or good artificial light.
4. DO NOT operate mower while under the influence of
alcohol or drugs.
5. After striking a foreign object or if mower vibrates
abnormally, STOP the engine, disconnect and
secure spark plug wire. Inspect the mow er for any
damage and repair the damage.
6. DO NOT mow near drop offs, ditches or
embankments. Operator could lose footing or
balance.
7. STAY ALERT for holes and other hidden hazards.
Tall grass can hide obstacles. Keep away from
ditches, washouts, culverts, fences and protruding
objects.
8. DO NOT mow on wet grass. Always be sure of your
footing. Keep a firm hold on the handle and walk,
never run. Slipping could cause injury.
9. DO NOT leave the machine with the engine running.
STOP BLADE and STOP ENGINE before leaving the
operators position for any reason.
10. Before cleaning, repairing or inspecting make
certain engine, blade and all moving parts have

catcher or guards in place. DO NOT point discharge
at people, passing cars, windows or doors.
13. Slow down before turning.
14. Watch out for traffic when near or crossing
roadways.
15. DO NOT operate engine in enclosed areas. Engine
exhaust gases contain carbon monoxide, a deadly
poison.
MAINTENANCE AND STORAGE
1. DO NOT store mower 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 reach of children in a well
ventilated, unoccupied building.
2. Keep mower and 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. Keep all bolts, especially blade bolts, nuts and
screws properly tight. Check that all cotter pins are
in proper position.
5. Alw ays provide adequate ventilation when running
engine. Engine exhaust gases contain carbon
monoxide, a deadly poison.
6. Service engine and make adjustments only when
engine is stopped. Removed spark plug wire from
spark plug and secure wire away from spark plug to
prevent accidental starting.
7. DO NOT change engine governor speed settings or
overspeed engine.
8. Check grass bag assembly frequently for wear or
deterioration to avoid thrown objects and exposure
to moving parts. Replace with new bag if loose
seams or tears are evident. Replace slider or bag
adapter if broken or cracked.
9. Mower blades are sharp and can cut. Wrap the
blades or wear heavy leather gloves and use
CAUTION when handling them.
10. DO NOT test for spark by grounding spark plug next
to spark plug hole; spark plug could ignite gas
exiting engine.

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
non-concrete surface.
3. Remove battery cell caps. Fill cells with electrolyte
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 (-) terminal.
IMPORTANT: Never place anything in battery other than
specified electrolyte.
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 to proper 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 (-) cable (black) last, to negative terminal (-)
on battery using bolt and nut. Apply a small amount of
grease over terminals to prevent corrosion.
WARNING
DO NOT over fill battery with electrolyte. Shield the
positive terminal with terminal cover located on battery
harness. This prevents metal from touching the
positive terminal, which could cause sparks. 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 walk
behind. Never use “BOOST” chargers on the battery.

0% Charged Less than 1.100 Less than 11.80v Zero Balls Floating
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 bring
fluid to proper level.
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.
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’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.
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.
