DANGER:
This machine was built to be operated according to the rules for safe operation in this
manual. As with any type of power equipment, carelessness or error on the part of the operator can
result in serious injury. This machine is capable of amputating hands and feet and throwing objects.
Failure to observe the following safety instructions could result in serious injury or death.

8.
Read this operator's manual carefully in its entirety
before attempting to assemble this machine. Read,
understand, and follow all instructions on the machine
and in the manual(s) before operation. Be completely
familiar with the controls and the proper use of this
machine before operating it. Keep this manual in a safe
place for future and regular reference and for ordering
replacement parts.
This machine is a precision piece of power equipment,
not a plaything. Therefore, exercise extreme caution at all
times. Your unit has been designed to perform one job: to
mow grass. Do not use it for any other purpose.
Never allow children under 14 years old to operate this
machine. Children 14 years old and over should read and
understand the operation instructions and safety rules in
this manual and should be trained and supervised by a
parent. Only responsible individuals who are familiar with
these rules of safe operation should be allowed to use
this machine.
Thoroughly inspect the area where the equipment is to
be used. Remove all stones, sticks, wire, bones, toys and
other foreign objects which could be tripped over or
picked up and thrown by the blade. Thrown objects can
cause serious personal injury. Plan your mowing pattern
to avoid discharge of matedal toward roads, sidewalks,
bystanders and the like. Also, avoid discharging material
against a wall or obstruction which may cause
discharged material to ricochet back toward the operator.
To help avoid blade contact or a thrown object injury, stay
in the operator zone behind the handles and keep
children, bystanders, helpers and pets at least 75 feet
from the mower while it is in operation. Stop machine if
anyone enters the area.
Always wear safety glasses or safety goggles during
operation and while performing an adjustment or repair to
protect your eyes. Thrown objects which ricochet can
cause serious injury to the eyes.
Wear sturdy, rough-soled work shoes and close-fitting
slacks and shirts. Shirts and pants that cover the arms
and legs and steel-toed shoes are recommended. Never
operate this machine in bare feet, sandals, slippery or
light weight (e.g. canvas) shoes.

Do not put hands or feet near rotating parts or under the
cutting deck. Contact with the blade can amputate hands
and feet.
A missing or damaged discharge cover can cause blade
contact or thrown object injuries.
Many injuries occur as a result of the mower being puned
over the foot during a fall caused by slipping or tripping.
Do not hold on to the mower if you are falling; release the
handle immediately.
Never pull the mower back toward you while you are
walking. If you must back the mower away from a wall or
obstruction first look down and behind to avoid tripping
and then follow these steps:
a. Step back from the mower to fully extend your
arms.
b. Be sure you are well balanced with sure footing.
c. Pull the mower back slowly, no more than half way
toward you.
d. Repeat these steps as needed.
Do not operate the mower while under the influence of
alcohol or drugs.
Do not engage the self-propelled mechanism on units so
equipped while starting engine.
The blade control handle is a safety device. Never
attempt to bypass its operation. Doing so makes the
safety device inoperative and may result in personal
injury through contact with the rotating blade. The blade
control handle must operate easily in both directions and
automatically return to the disengaged position when
released.
Never operate the mower in wet grass. Always be sure of
your footing. A slip and fall can cause serious personal
injury. If you feel you are losing your footing, release the
blade control handle immediately and the blade will stop
rotating within three seconds.
Mow only in daylight or in good artificial light. Walk, never
run.
Stop the blade when crossing gravel drives, walks or
roads.
If the equipment should start to vibrate abnormally, stop
the engine and check immediately for the cause.
Vibration is generally a warning of trouble.

SlopeOperation
Slopes are a major factor related to slip and fall accidents
which can result in severe injury. Operation on slopes
requires extra caution. If you feel uneasy on a slope, do not
mow it. For your safety, use the slope gauge included as part
of this manual to measure slopes before operating this unit on
a sloped or hilly area. If the slope is greater than 15 degrees,
do not mow it.

Wash your skin and change clothes immediately.
Use only an approved gasoline container.
Never fill containers inside a vehicle or on a truck or
trailer bed with a plastic liner. Always place containers on
the ground away from your vehicle before filling.
When practical, remove gas-powered equipment from
the truck or trailer and refuel it on the ground. If this is not
possible, then refuel such equipment on a trailer with a
portable container, rather than from a gasoline dispenser
nozzle.
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.
Extinguish all cigarettes, cigars, pipes and other sources
of ignition.
Never fuel machine indoors because flammable vapors
will accumulate in the area.
Never remove gas cap or add fuel while the engine is hot
or running. Allow engine to cool at least two minutes
before refueling.
Neverover fill fueltank. Fill tank to no more than Y_inch
below bottom of filler neck to provide space for fuel
expansion.
Replace gasoline cap and tighten securely.
If gasoline is spined, wipe it off the engine and equipment.
Move unit to another area. Wait 5 minutes before starting
the engine.
Never store the machine or fuel container inside where
there is an open flame, spark or pilot light as on a water
heater, space heater, furnace ,clothes dryer or other gas
appliances.
To reduce fire hazard, keep mower free of grass, leaves,
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel soaked debris.
Allow a mower to cool at least 5 minutes before storing.
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
mower and the mowing activity. They do not understand the
dangers. Never assume that children will remain where you
last saw them.
General Service:

Mower blades are sharp and can cut. Wrap the blade or
wear gloves, and use extra caution when servicing them.
Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.
Never tamper with safety devices. Check their proper
operation regularly.
After striking a foreign object, stop the engine, disconnect
the spark plug wire and ground against the engine.
Thoroughly inspect the mower for any damage. Repair
the damage before starting and operating the mower.
Never attempt to make a wheel or cutting height
adjustment while the engine is running.
9.
Grass catcher components, discharge cover, and trail
shield are subject to wear and damage which could
expose moving parts or allow objects to be thrown. For
safety protection, frequently check components and
replace immediately with original equipment
manufacturer's (O.E.M.) parts only, listed in this manual.
"Use of parts which do not meet the original equipment
specifications may lead to improper performance and
compromise safety!"
10. Do not change the engine governor setting or overspeed
the engine. The governor controls the maximum safe
operating speed of the engine.

UsingYourLawnMower
Be sure that the lawn is clear of stones, sticks, wire, or
other objects which could damage the lawn mower or
the engine. Such objects could be accidently thrown by
the mower in any direction and cause serious personal
injury to the operator and others.
For best results, do not cut wet grass because it tends
to stick to the underside of the mower, preventing
proper discharge of grass clippings, and could cause
you to slip and fall. New grass, thick grass, or wet grass
may require a narrower cut.
Mulching
For effective mulching, do not cut wet grass because it
tends to stick to the underside of the deck, preventing
proper mulching of grass clippings. New or thick grass
may require a narrower cut. The ground speed should
be adjusted to the condition of the lawn. If mowing has
been delayed and the grass has been allowed to grow
in excess of 4", mulching is not recommended. Mow
using the side discharge to reduce the grass height to
For a healthier lawn, never cut off more than one-third
of the total length of the grass. Your lawn should be cut
in the fall as long as there is growth. This mower is
designed to be operated at full throttle to give you the
best cut and do the most effective job of mowing or
mulching.

CuttingBlade Removal,Replacement,and Sharpening
•
When removing the cutting blade for sharpening or
replacement, protect your hands with a pair of
heavy gloves or use a heavy rag to hold the blade.
•
Remove the bolt and the blade bell support which
hold the blade and the blade adapter to the engine
crankshaft. See Figure 11.
•
Remove the blade and the adapter from the
crankshaft.

Maintenance
NOTE: When tipping the unit or emptying the fuel tank
keep the air cleaner side of engine up. Never tip the
mower more than 90 degrees and do not leave the
mower tipped for any length of time. Oil can drain into
the upper part of the engine causing a starting problem.

a foreign object. Replace when necessary.
When sharpening the blade, follow the original angle of
grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade will
cause excessive vibration when rotating at high
speeds. It may cause damage to the mower, and could
break causing personal injury.
Maintain engine oil as instructed in the separate
engine manual packed with your unit.
Service air cleaner every 25 hours under normal
conditions. Poor engine performance and flooding
usually indicate that the air cleaner should be
serviced. To service the air cleaner, refer to the
separate engine manual packed with your unit.
The spark plug should be cleaned and the gap
reset once a season. Spark plug replacement is
recommended at the start of each mowing season.
Clean the engine regularly with a cloth or brush. Keep
the cooling system (blower housing area) clean to
permit proper air circulation which is essential to engine
performance and life. Be certain to remove all grass,
dirt, and combustible debris from muffler area.
Deck
The underside of the mower deck should be cleaned
after each use to prevent a buildup of grass clippings,
leaves, dirt, or other matter. If this debris is allowed to
accumulate, it will invite rust and corrosion, and may
prevent proper mulching, discharge, or bagging. The
deck may be cleaned by tilting the mower and scraping
clean with a suitable tool (make certain the spark plug
wire is disconnected).

The following steps should be taken to prepare your
lawn mower for storage.
•
•
Clean and lubricate mower thoroughly as described
in the lubrication instructions.
NOTE: When storing any type of power equipment in a
poorly ventilated or metal storage shed, care should be
taken to rust-proof the equipment. Using a light oil or
silicone, coat the equipment, especially cables and all
moving parts.
IMPORTANT:We do not recommend the use of a
pressure washer or garden hose to clean your unit.
•
Coat mower's cutting blade with chassis grease to
prevent rusting.
Store mower in a dry, clean area. Do not store next
to corrosive materials, such as fertilizer.
