manual. As with any ty pe of power equipment, carelessnes s or error on the part of the oper ator can
result in serious in jury. This lawn mow er is capable of am putating han ds and feet and thro wing objects.
Failure to observe the following safety instructions could result in serious injury or death.
: Your lawn mower was built to be operated according to the ru les for safe operation in this
GENERAL OPERA TION
•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.
•Your rotary mower 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
a power mower. Children 14 years old and over
should only operate mower under close parental
supervision. Only responsible individuals who are
familiar with these rules of safe operation should be
allowed to use your mower.
•Keep the area of operation clear of all persons,
particularly small children and pets. Stop engine
when they are in the vicinity of your mower to help
prevent blade contact or thrown object injury.
Although the area of operation should be
completely cleared of foreign objects, an object
may have been overlooked and could be
accidenta lly thrown by the mower in an y directi on
and cause serious personal injury to the operator or
any others allowed in the area.
•Wear sturdy, rough-soled work shoes and closefitting slacks and shirts. Shirts and pants that cover
the arms and legs and steel-toed shoes are
recommended. Do not wear loose fitting clothes or
jewelry. They can be caught in moving parts. Never
operate a unit in bare feet, sandals, slippery or light
weight (e.g. canvas) shoes.
•Always wear safety glasses or safety goggles
during operation or while performing an adjustment
or repair, to protect eyes from foreign objects that
may be thrown from the machine in any direction.
•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 picked up and thrown by the mower in any
direction and cause serious personal injury to the
operator or an y others al lowed in th e area. Pla n
your mowing pattern to avoid discharge of material
toward roads, sidewalks, bystanders and the like.
To help avoid a thrown objects injury, keep
children, bystanders and helpers at least 75 feet
from the mower while it is in operation.
•Do not put hands or feet near or under rotating
parts. Keep clear of discharge opening at all times
as the rotating blade can cause injury.
•Many injuries occur as a result of the mower being
pulled over the foot during a fall. Do not hang on to
the mower if you are falling; release the handle
immediately.
•Never pull the m ower towar d you while you ar e
walking. If yo u must back th e mower away from a
wall or obstruction first look down and behind, and
then follow these steps:
•Step back from the mower to fully extend your
arms.
•Be sure you are we ll balan ced with sur e footin g.
•Pull the mower back slowly, no more than half way
toward you.
•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. Keep a firm hold on the
handle and walk, never run. 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 good artificial light.
•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.
•Shut the engine off and wait until the blade comes
to a complete stop before removing the grass
catcher or unclogging the chute. The cutting blade
continues to rotate for a few seconds after the
engine is shut off. Never place any part of the body
in the blade area until you are sure the blade has
stopped rotating.
•Never operate mower without proper guards, grass
catcher, plates or other safety protective devices in
place.
•Muffler and engine become hot and can cause a
burn. Do not touch.
•Only use accessories approved for this machine by
the manufacturer. Read, understand, and follow all
instructions provided with the approved accessory.
•If situations occur which are not covered in this
manual, use care and good judgment. Contact your
dealer for assistance.
SLOPE OPERA TI ON
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
as shown on the slope gauge, do not operate this unit on
that area or serious injury could result.
DO:
•Mow across the face of slopes; never up and down.
Exercise extreme caution when changing direction
on slopes.
•Always be sure of your footing. A slip and fall can
cause serious personal injury. If you feel you are
losing your balance release the blade control
handle immediately and the blade will stop in less
than 3 seco nds.

disconnect the spark plug wire before
performing any maintenance work or
adjustments on your lawn mower.
Cleaning Mower
The underside of the mower deck should be cleaned
after each use to prevent any build-up of grass
clippings, leaves, dirt, or other debris. If this debris is
allowed to accumulate, it will result in rust and
corrosion.
NOTE: We do not recommend the use of pressure
washers or garden hose to cl ean your unit. They may
cause damage to electric components, spindles,
pulleys, bearings, or the engine. The use of water will
result in shortened life and reduce serviceability.
•Disconnect spark plug wire.
•Drain the gasoline from the lawn mower, or place a
piece of plastic under the gas cap.
•Tip the mower so that it rests on the housing. Keep
the side with the air cleaner facing UP. Hold the
mower firmly.
•Scrape and clean the underside of the deck with a
suitable tool. Do NOT spray with water.
•Put the mower back on its wheels on the ground. If
you had put plastic under the gas cap, make sure to
remove it now.
WARNING: Never tip the mower more than
90 degrees in any directions and do not
leave the mower tipped for any length of
time. Oil can drain into the upper part of th e
engine causing a starting problem.
Engine Maintenance
•A list of key maintenance jobs required for good
performance by the mower is given below. Follow
the accompanying engine manual for detailed list
and instructions.
•Change engine oil after the first two operating
hours and every 25 operating hours thereafter.
Check the oil level before starting the engine every
time.
•Service foam filter in the air cleaner every 25 hours
of use and replace the paper filter component every
100 hours. You may have to service the air filter
more frequently if you are operating the mower
under extremely dusty conditions.
•Clean the engine periodically. Remove dirt and
debris with a cloth or brush.
•Clean the spark plug and reset the gap to .030” at
least once a season or every 50 hours of operation.
Spark plug replacement is recommended at the
start of each season. Refer to the engine manual
for correct spark plug type.
•Inspect muffler periodically, and replace if
necessary. Damaged mufflers or spark arresters
can create a fire hazard. Make sure to avoid muffler
and surrounding areas while the mower engine is
hot because temperature of these areas of the
engine may ex ceed 150
o
F.
Lubrication
Wheels
•Lubricate the wheels and bearings, if so equipped,
at least once a season with light oil or engine oil.
Also, if the wheels are removed for any reason,
lubricate the surface of the axle bolt and the inner
surface of the wheel with light oil.
Chute Deflector & Rear Discharge Door
•Lubricate the torsion spring and the pivot point on
each end of the chute deflector and the rear
discharge door using a light oil. This will prevent
rusting and ensure that the deflector, which is a
safety device, can always work properly.
Engine
•Follow the engine manual instructions and
recommended schedule for lubricating engine
components.
