Safety
Improper use or maintenance by the operator or
owner can result in injury. To reduce the potential
for injury, comply with these safety instructions
and always pay attention to the safety alert
symbol, which means CAUTION, WARNING, or
DANGER—“personal safety instruction.” Failure
to comply with the instruction may result in
personal injury or death.
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.
HOW TO AVOID THE HAZARD
• Do not run engine indoors or in an enclosed
area.
This product is designed for cutting and recycling
grass or, when equipped with a grass bagger, for
catching cut grass. Any use for purposes other than
these could prove dangerous to user and bystanders.
Note: This engine is NOT equipped with a
spark arrestor muffler. Use or operation
of this mower in the State of California
on any forest-covered or unimproved
grass-covered land, without an
approved spark arrester muffler, is a
violation of the law. Other states may
have similar laws.
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.
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.
2
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.
18. Wear seat belt when operating a machine with
ROPS (roll over protection).
19. Wear ear protection when operating this
machine.
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
• Mow up and down slopes greater than 5°, not
across.
• Mow downhill only on slopes less than 10°,
Mow uphill only on slopes less than 15°
• 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.
• 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.
• When operating machine on slopes, banks or
near drop offs, always have ROPS (roll over
protection) installed.
• When operating a machine with ROPS (roll over
protection) always use seat belt.
• Be certain that the seat belt can be released
quickly if the machine is driven or rolls into
ponds of water.
• Check carefully for overhead clearances (i.e.
branches, doorways, electrical wires) before
driving under any objects and do not contact
them.
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.
• 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.
• Use extra care with grass catchers or other
attachments. These can change the stability of
the machine.

Safety
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.
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.
4. Keep nuts and bolts tight, especially the blade
attachment bolts. Keep equipment in good
condition.
5. Never tamper with safety devices. Check safety
systems for proper operation before each use.
6. Keep the machine free of grass, leaves, or other
debris build-up. Clean up oil or fuel spillage.
Allow the machine to cool before storing.
7. Stop and inspect the equipment if you strike an
object. Repair, if necessary, before restarting.
8. Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown.
Frequently check components and replace with
manufacturer’s recommended parts, when
necessary.
9. Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves, and use extra caution
when servicing them.
10. Use only genuine replacement parts to ensure
that original standards are maintained.
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.
A. Use only an approved container.
B. Never remove the gas cap or add fuel when
the engine is running. Allow the engine to
cool before refueling. Do not smoke.
C. Never refuel the machine indoors.
D. Never store the machine or fuel container
inside where there is an open flame, such as
near a water heater or furnace.
3. Never run a machine inside a closed area.
11. Check brake operation frequently. Adjust and
service as required.
12. Battery acid is poisonous and can cause burns.
Avoid contact with skin, eyes and clothing.
Protect your face, eyes and clothing when
working with a battery.
13. Battery gases can explode. Keep cigarettes,
sparks and flames away from battery.
14. Hydraulic fluid escaping under pressure can
penetrate the skin and cause injury. Use
cardboard or paper to find hydraulic leaks.
15. Never modify ROPS (roll over protection)
frames or structures because they are specifically
designed, sized, located and tested for injury
reduction. If a rollover occurs, a modified ROPS
will not provide adequate protection.

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.
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
• 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 the fuel tank cap and remove the
cap. Add unleaded regular gasoline until the
level is to the bottom of the filler neck. Do not
fill the neck completely full, this space in the
tank allows gasoline to expand.
3. Install fuel tank cap securely. Wipe up any
gasoline that may have spilled.
Check Engine Oil Level
Before you start the engine and use the machine,
check the oil level in the engine crankcase; refer to
Checking Oil Level, page 23.
