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 pro duc tive harm. Wash
hands after handling.

CAUTION: Muffl er 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 operate the mower when barefoot or wearing
open sandals. Always wear substantial foot wear.

• 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 artifi cial light.

• Do not operate the machine while under the infl uence
of alcohol or drugs.

• Never operate machine in wet grass. Always be sure of
your footing: keep a fi rm 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 cause
slipping.

III. CHILDREN

Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to

Never

the machine and the mowing activity.

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.

IV. SAFE HANDLING OF GASOLINE

Use extreme care in handling gasoline. Gasoline is ex­tremely fl ammable 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 run-

ning. Allow engine to cool before refueling.

• Never refuel the machine indoors.

• Never store the machine or fuel container where there
is an open fl ame, spark or pilot light such as a water
heater or on other appliances.

• Never fi ll 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 fi lling.

• 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 overfi ll 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

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

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.

HOW TO USE YOUR LAWN MOWER

ENGINE SPEED

The engine speed was set at the factory for optimum per­formance. Speed is not adjustable.

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.

• 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 (See Fig. 4)

• 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.

• 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.

NOTE: If after releasing the drive control the mower will
not roll backwards, push the mower forward slightly to
disengage drive wheels.

OPERATOR PRESENCE CONTROL BAR

2. Rotate turnbuckle on drive control to increase drive
speed.

3. Operate mower to test drive speed. Readjust as re­quired.

and should be re placed.

ADJUSTMENT TURNBUCKLE
