the potential for injury, comply with these safety
instructions and always pay attention to the safety
alert
WARNING, or DANGER—“personal safety
instruction.” Failure to comply with the
instruction may result in personal injury or death.
symbol, which means CAUTION,
Safe Operating Practices
This product is capable of amputating hands and feet
and throwing objects. Always follow all safety
instructions to avoid serious injury or death.
POTENTIAL HAZARD
• Engine exhaust contains carbon monoxide,
which is an odorless, deadly poison.
WHAT CAN HAPPEN
• Carbon monoxide can kill you and is also
known to the State of California to cause
birth defects.
General Operation
1. Read, understand, and follow all instructions in
the operator’s manual and on the machine before
starting.
2. Allow only responsible adults who are familiar
with the instructions to operate the machine.
3. Clear the area of objects such as rocks, toys,
wire, etc., which could be picked up and thrown
by the blade.
4. Be sure the area is clear of other people before
mowing. Stop the machine if anyone enters the
area.
5. Never carry passengers.
6. Do not mow in reverse unless absolutely
necessary. Always look down and behind before
and while backing.
7. Be aware of the mower discharge direction and
do not point it at anyone. Do not operate the
mower without either the entire grass catcher or
the guard in place.
8. Slow down before turning. Sharp turns on any
terrain may cause loss of control.
HOW TO AVOID THE HAZARD
• Do not run engine indoors or in an enclosed
area.
2
9. Never leave a running machine unattended.
Always turn off blades, set parking brake, stop
engine, and remove key before dismounting.
10. Turn off blades when not mowing.
11. Keep hands, feet, hair and loose clothing away
from attachment discharge area, underside of
mower and any moving parts while engine is
running.
12. Stop the engine before removing the grass
catcher or unclogging the chute.
13. Mow only in daylight or good artificial light.
Safety
14. Do not operate the machine while under the
influence of alcohol or drugs.
15. Watch for traffic when operating near or crossing
roadways.
16. Use extra care when loading or unloading the
machine onto a trailer or truck.
17. Do not touch equipment or attachment parts
which may be hot from operation. Allow to cool
before attempting to maintain, adjust or service.
Slope Operation
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.
DO
• Keep all movement on slopes slow and gradual.
Do not make sudden changes in speed or
direction.
• Avoid starting or stopping on a slope. If tires
lose traction, disengage the blades and proceed
slowly straight down the slope.
DO NOT
• Do not operate machine on hillsides or slopes
exceeding 15°.
• Avoid turning on slopes. If you must turn, turn
slowly and gradually downhill, if possible.
• Do not mow near drop-offs, ditches, or
embankments. The machine could suddenly turn
over if a wheel goes over the edge of a cliff or
ditch, or if an edge caves in.
• Do not mow on wet grass. Reduced traction
could cause sliding.
• Mow up and down slopes greater than 5°, not
across.
• Mow downhill only on slopes above 10°, never
mow uphill. If a steep slope must be ascended,
back up the hill, and drive forward down the hill,
keeping the machine in gear.
• Remove obstacles such as rocks, tree limbs, etc.
from the mowing area. Watch for holes, ruts or
bumps, as uneven terrain could overturn the
machine. Tall grass can hide obstacles.
• Use slow speed. Choose a low gear so that you
will not have to stop or shift while on the slope.
• Follow the manufacturer’s recommendations for
wheel weight or counterweights to improve
stability.
• Use extra care with grass catchers or other
attachments. These can change the stability of
the machine.
• Do not try to stabilize the machine by putting
your foot on the ground.
• Do not use a grass catcher on steep slopes.
Heavy grass bags could cause loss of control or
overturn the machine.
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. The following requirements must be
followed to prevent injury to children.
1. Keep children out of the mowing area and under
the watchful care of another responsible adult.
2. Be alert and turn the machine off if children
enter the area.
3. Before and while backing, look behind and down
for small children.
3
Safety
4. Never carry children. They may fall off and be
seriously injured or interfere with safe machine
operation.
5. Never allow children to operate the machine.
6. Use extra care when approaching blind corners,
shrubs, trees, the end of a fence or other objects
that may obscure vision.
Service
1. Stop the engine and disconnect spark plug
wire(s) before performing any service, repairs,
maintenance or adjustments.
2. Use extra care when handling gasoline and other
fuels. They are flammable and vapors are
explosive.

Gasoline and Oil
Recommended Gasoline
Use UNLEADED Regular Gasoline suitable for
automotive use (85 pump octane minimum). Leaded
regular gasoline may be used if unleaded regular is
not available.
IMPORTANT: Never use methanol, gasoline
containing methanol, or gasohol containing
more than 10% ethanol because the fuel
system could be damaged. Do not mix oil with
gasoline.
POTENTIAL HAZARD
• In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
• A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AVOID THE HAZARD
• Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is cold.
Wipe up any gasoline that spills.
• Do not fill the fuel tank completely full.
Add gasoline to the fuel tank until the level
is 1/4” to 1/2” (6 mm to 13 mm) below the
bottom of the filler neck. This empty space
in the tank allows gasoline to expand.
• Never smoke when handling gasoline, and
stay away from an open flame or where
gasoline fumes may be ignited by a spark.
• Store gasoline in an approved container
and keep it out of the reach of children.
Never buy more than a 30-day supply of
gasoline.
POTENTIAL HAZARD
• In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
• A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AVOID THE HAZARD
• Always place gasoline containers on the
ground away from your vehicle before
filling.
• Do not fill gasoline containers inside a
vehicle or on a truck or trailer bed because
interior carpets or plastic truck bed liners
may insulate the container and slow the
loss of any static charge.
• When practical, remove gas–powered
equipment from the truck or trailer and
refuel the equipment with its wheels on the
round.
• If this is not possible, then refuel such
equipment on a truck or trailer from a
portable container, rather than from a
gasoline dispenser nozzle.
• If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of
the fuel tank or container opening at all
times until fueling is complete.
10
Gasoline and Oil
Stabilizer/Conditioner
Add the correct amount of gas stabilizer/conditioner
to the gas. Using a stabilizer/conditioner in the
machine:
• Keeps gasoline fresh during storage of 90 days
or less. For longer storage it is recommended
that the fuel tank be drained.
• Cleans the engine while it runs
• Eliminates gum-like buildup in the fuel system,
which causes hard starting
IMPORTANT: Never use fuel additives
containing methanol or ethanol.
Filling the Fuel Tank
1. Shut the engine off and set the parking brake.
2. Clean around each fuel tank cap and remove the
cap. Add unleaded regular gasoline to both fuel
tanks, until the level is 1/4 to 1/2 inch (6 mm to
13 mm) below the bottom of the filler neck. This
space in the tank allows gasoline to expand. Do
not fill the fuel tanks completely full.
3. Install fuel tank caps securely. Wipe up any
gasoline that may have spilled.
4. Fuel gauge is located in right side tank.
Check Engine Oil Level
Before you start the engine and use the machine,
check the oil level in the engine crankcase; refer to
