TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.
• Do not operate the mower when barefoot or wearing
open sandals. Always wear substantial foot wear.
Look for this symbol to point out im por tant
safety precautions. It means CAUTION!!!
BE COME ALERT!!! YOUR SAFE TY IS IN VOLVED.
CAUTION: Always disconnect spark plug wire and
place wire where it cannot contact spark plug in
order to prevent ac ci den tal starting when setting
up, trans port ing, adjusting or making re pairs.
WARNING: Engine exhaust, some of its
con stit u ents, and certain vehicle com po nents
contain or emit chem i cals known to the State of
Cal i for nia to cause can cer and birth defects or
oth er re pro duc tive harm.
WARNING: Battery posts, terminals and related
ac ces so ries contain lead and lead compounds,
chemicals known to the State of Cal i for nia to cause
can cer and birth defects or oth er re produc tive
harm. Wash hands after handling.
CAUTION: Muffler and other engine parts become
extremely hot during operation and remain hot
after engine has stopped. To avoid severe burns
on contact, stay away from these areas.
I. GENERAL OPERATION
• Read, understand, and follow all instructions on the
machine and in the manual(s) before starting. Be
thor ough ly familiar with the controls and the proper
use of the machine before starting.
• Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
• Only allow responsible individuals, who are familiar
with the instructions, to operate the machine.
• Clear the area of objects such as rocks, toys, wire,
bones, sticks, etc., which could be picked up and
thrown by the blade.
• Be sure the area is clear of other people before mow ing.
Stop machine if anyone enters the area.
• Do not pull mower backwards unless absolutely
nec es sary. Always look down and behind before and
while moving backwards.
• Never direct discharged material toward anyone.
Avoid discharging material against a wall or obstruction.
Material may richochet back toward the operator. Stop
the blade when crossing gravel surfaces.
• Do not operate the mower without proper guards,
plates, grass catcher or other safety protective devices
in place.
• See manufacturer’s instructions for proper operation
and installation of accessories. Only use accessories
approved by the manufacturer.
• Stop the blade(s) when crossing gravel drives, walks,
or roads.
• Stop the engine (motor) whenever you leave the
equip ment, before cleaning the mower or unclogging
the chute.
• Shut the engine (motor) off and wait until the blade
comes to complete stop before removing grass catch er.
• Mow only in daylight or good artificial light.
• Do not operate the machine while under the influence
of alcohol or drugs.
• Never operate machine in wet grass. Always be sure
of your footing: keep a firm hold on the handle and
walk; never run.
• Disengage the self-propelled mechanism or drive clutch
on mowers so equipped before starting the engine
(motor).
• If the equipment should start to vibrate abnormally,
stop the engine (motor) and check immediately for
the cause. Vibration is generally a warning of trouble.
• Always wear safety goggles or safety glasses with side
shields when operating mower.
II. SLOPE OPERATION
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.
DO:
• Mow across the face of slopes: never up and down. Exercise extreme caution when changing direction on slopes.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts, or bumps. Tall grass can hide
obstacles.
DO NOT:
• Do not trim near drop-offs, ditches or embankments.
The operator could lose footing or balance.
• Do not trim excessively steep slopes.
• Do not mow on wet grass. Reduced footing could
2
cause slipping.
III. 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.
• Keep children out of the trimming area and under the
watchful care of another re spon si ble adult.
• Be alert and turn machine off if children enter the area.
• Before and while walking backwards, look behind and
down for small children.
• Never allow children to operate the machine.
• Use extra care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.
WARNING: This lawn mower is equipped with an
internal com bus tion engine and should not be
used on or near any un im proved forest-covered,
brush-covered or grass-cov ered land unless
the engine’s exhaust system is equipped with a
spark arrester meeting applicable local or state
laws (if any). If a spark arrester is used, it should
be maintained in effective working order by the
operator.
A spark arrester for the muffler is available through
your nearest authorized service center.
IV. SAFE HANDLING OF GASOLINE
Use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Use only an approved container.
• Never remove gas cap or add fuel with the engine
running. Allow engine to cool before refueling.
• Never refuel the machine indoors.
• Never store the machine or fuel container where there
is an open flame, spark or pilot light such as a water
heater or on other appliances.
• Never fill containers inside a vehicle, on a truck or trailer
bed with a plastic liner. Always place containers on
the ground away from your vehicle before filling.
• Remove gas-powered equipment from the truck or
trailer and refuel it on the ground. If this is not possible,
then refuel such equipment 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.
• If fuel is spilled on clothing, change clothing immediately.
• Never overfill fuel tank. Replace gas cap and tighten
securely.
V. GENERAL SERVICE
• Never run a machine inside a closed area.
• Never make adjustments or repairs with the engine
(motor) running. Disconnect spark plug wire, and keep
wire away from plug to prevent accidental starting.
• Keep nuts and bolts, especially blade attachement
bolts, tight and keep equipment in good condition.
• Never tamper with safety devices. Check their proper
operation regularly.
• Keep machine free of grass, leaves, or other debris
build-up. Clean oil or fuel spillage. Allow machine to
cool before storing.
• Stop and inspect the equipment if you strike an object.
Repair, if necessary, before restarting.
• Never attempt to make wheel height adjustments while
the engine (motor) is running.
• Grass catcher components are subject to wear, dam age, and deterioration, which could expose moving
parts or allow objects to be thrown. Frequently check
com po nents and replace with manufacturer’s rec om mend ed parts, when necessary.
• Mower blade is sharp and can cut. Wrap the blade or
wear gloves, and use extra caution when servicing it.
• Do not change the engine governor setting or overspeed the engine.
• Maintain or replace safety and instruction labels, as
necessary.

OPERATION
OPERATION
ENGINE SPEED
The engine speed was set at the factory for optimum performance. Speed is not adjustable.
The operation of any lawn mower can result
in foreign objects thrown into the eyes, which
can result in severe eye damage. Always
wear safety glasses or eye shields while
operating your lawn mower or performing
any adjustments or repairs. We recommend
standard safety glasses or a wide vision safety mask over
spectacles.
IMPORTANT: This lawn mower is shipped WITHOUT OIL
OR GASOLINE in the engine.
WARNING: The blade turns when the engine is
running.
ENGINE ZONE CONTROL
CAUTION: Federal regulations require an engine
control to be installed on this lawn mower in order
to minimize the risk of blade contact injury. Do
not un der any cir cum stanc es attempt to defeat
the function of the operator control. The blade
turns when the engine is running.
NOTE: Your lawn mower is equipped with an operator
presence control bar which requires the operator to be
positioned behind the mower handle to start and operate
the mower.
DRIVE CONTROL
1. Self-propelling is controlled by hold ing the operator
presence control bar down to the handle and pulling
either drive control lever rearward to the handle. The
further toward the handle a lever is pulled, the faster
the unit will travel (Figure 6).
2. Forward motion will stop when either the operator
presence control bar or a drive control lever are
released. To stop forward motion without stop ping
engine, re lease a drive control lever only. Hold op er a tor
presence control bar down against handle to con tin ue
mowing without self-propelling (Figure 7).
NOTE: If after releasing the drive control the mower will
not roll backwards, push the mower forward slightly to
disengage drive wheels.
