and follow the warnings
and instructions
in this manual
and on the machine.
WARNING: Engine Exhaust, some of its constituents, and certain vehicle components contain
or emit chemicals known to the State of California to cause cancer and birth defects or other
reproductive harm.
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.
General Operation
1. 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. Keep this manual in a safe place for future
and regular reference and for ordering replacement parts.
2. Be completely familiar with the controls and the proper use of
this machine before operating it.
3. 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.
4. Never allow children under 14 years old to operate this
machine. Children 14 years old and over should read and
understand the instructions in this manual and should be
trained and supervised by a adult.
5. Only responsible individuals who are familiar with these rules
of safe operation should be allowed to use this machine.
6. 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.
7. Plan your mowing pattern to avoid discharge of material 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.
8. 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.
9. 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.
10. 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.
11. Do not put hands or feet near rotating parts or under the cutting
deck. Contact with the blade can amputate hands and feet.
12. A missing or damaged discharge cover can cause blade
contact or thrown object injuries.
13. Many injuries occur as a result of the mower being pulled
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.
14. 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.
15. Do not operate the mower while under the influence of alcohol or
drugs.
16. Do not engage the self-propelled mechanism on units so
equipped while starting engine.
17. 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.
18. 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.
19. Mow only in daylight or in good artificial light. Walk, never run.
20. Stop the blade when crossing gravel drives, walks or roads.
21. If the equipment should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is generally a warning of trouble.
22. 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.
23. Never operate mower without proper trail shield, discharge cover,
grass catcher, blade control handle or other safety protective
devices in place and working. Never operate mower with
damaged safety devices. Failure to do so, can result in personal
injury.
24. Muffler and engine become hot and can cause a burn. Do not
touch.
25. Never attempt to make a wheel or cutting height adjustment while
the engine is running.
26. Only use parts and accessories made for this machine by the
manufacturer. Failure to do so can result in personal injury.
27. When starting engine, pull cord slowly until resistance is felt, then
pull rapidly. Rapid retraction of starter cord (kickback) will pull
hand and arm toward engine faster than you can let go. Broken
bones, fractures, bruises or sprains could result.
28. If situations occur which are not covered in this manual, use care
and good judgment. Call customer assistance for the name of
your nearest servicing dealer.
Slope Operation
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.
Do:
Mow across the face of slopes; never up and down. Exercise
1.
extreme caution when changing direction on slopes.
2. Watch for holes, ruts, rocks, hidden objects, or bumps which can
cause you to slip or trip. Tall grass can hide obstacles.
4
3. 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
rotating within 3 seconds.
Do Not:
1. Do not mow near drop-offs, ditches or embankments, you could
lose your footing or balance.
2. Do not mow slopes greater than 15 degrees as shown on the slope
gauge.
3. Do not mow on wet grass. Unstable footing could cause slipping.
Children
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.
1. Keep children out of the mowing area and under the watchful
care of a responsible adult other than the operator.
2. Be alert and turn mower off if a child enters the area.
3. Before and while moving backwards, look behind and down for
small children.
4. Use extreme care when approaching blind corners, doorways,
shrubs, trees, or other objects that may obscure your vision of a
child who may run into the mower.
5. Keep children away from hot or running engines. They can suffer
burns from a hot muffler.
6. Never allow children under 14 years old to operate a power
mower. 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.
Service
Safe Handling Of Gasoline:
1. To avoid personal injury or property damage use extreme care
in handling gasoline. Gasoline is extremely flammable and the
vapors are explosive. Serious personal injury can occur when
gasoline is spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.
2. Use only an approved gasoline container.
3. 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.
4. 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.
5. 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.
6 Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
7. Never fuel machine indoors because flammable vapors will
accumulate in the area.
8. Never remove gas cap or add fuel while the engine is hot or run
ning. Allow engine to cool at least two minutes before refueling.
9. Never over fill fuel tank. Fill tank to no more than ½ inch below
bottom of filler neck to provide for fuel expansion.
10. Replace gasoline cap and tighten securely.
11. If gasoline is spilled, wipe it off the engine and equipment. Move
unit to another area. Wait 5 minutes before starting the engine.
12. Never store the machine or fuel container near an open flame,
spark or pilot light as on a water heater, space heater, furnace,
clothes dryer or other gas appliances.
-
13. 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.
14. Allow a mower to cool at least 5 minutes before storing.
General Service:
1. Never run an engine indoors or in a poorly ventilated area.
Engine exhaust contains carbon monoxide, an odorless and
deadly gas.
2. Before cleaning, repairing, or inspecting, make certain the
blade and all moving parts have stopped. Disconnect the spark
plug wire and ground against the engine to prevent unintended
starting.
3. Check the blade and engine mounting bolts at frequent
intervals for proper tightness. Also, visually inspect blade for
damage (e.g., bent, cracked, worn) Replace blade with the
original equipment manufacture’s (O.E.M.) blade only, listed
in this manual. “Use of parts which do not meet the original
equipment specifications may lead to improper performance
and compromise safety!”
4. Mower blades are sharp and can cut. Wrap the blade or wear
gloves, and use extra caution when servicing them.
5. Keep all nuts, bolts, and screws tight to be sure the equipment
is in safe working condition.
6. Never tamper with safety devices. Check their proper operation
regularly.
7. 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.
8. 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.
11. Check fuel line, tank, cap, and fittings frequently for cracks or
leaks. Replace if necessary.
12. Do not crank engine with spark plug removed.
13. Maintain or replace safety labels, as necessary.
14. Observe proper disposal laws and regulations. Improper
disposal of fluids and materials can harm the environment.
Do not modify engine
To avoid serious injury or death, do not modify engine in any way.
Tampering with the governor setting can lead to a runaway engine
and cause it to operate at unsafe speeds. Never tamper with
factory setting of engine governor.

General Recommendations
1. Always observe safety rules when performing
any maintenance.
2. The warranty on this lawn mower does not cover
items that have been subjected to operator abuse
or negligence. To receive full value from warranty,
operator must maintain the lawn mower as
instructed here.
3. Changing of engine-governed speed will void
engine warranty.
4. All adjustments should be checked at least once
each season.
5. Periodically check all fasteners and make sure these
are tight.
Lubrication
1. Lubricate the pivot points on the blade control handle
at least once a season with light oil. The blade
control must operate freely in both directions. See
Figure 10.
2. If your mower is equipped with ball bearing wheels,
lubricate at least once a season with a light oil, all
other types require no lubrication. However, if the
wheels are removed for any reason, lubricate the
surface of the axle bolt and the inner surface of the
wheel with light automotive oil.
3. Lubricate the torsion spring and pivot point periodically with light oil to prevent rust. See Figure 10.
4. Follow the accompanying engine manual for lubrication schedule and instruction.
Engine
1. Refer to the separate engine manual for engine
maintenance instructions.
2. Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
3. Under normal conditions service air cleaner as
instructed in the separate engine manual packed with
your unit. Clean every few hours under extremely
dusty conditions. Poor engine performance and
flooding usually indicates that the air cleaner should be
serviced.
4. 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; check
engine manual for correct plug type and gap specifications.
NOTE: This spark ignition system meets all requirements of the Canadian Interference-Causing Equipment
Regulations.
5. Clean the engine regularly with a cloth or brush.

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.
The deck may be cleaned by tilting the mower and scraping clean with a suitable tool (make certain the spark plug
wire is disconnected).
Blade Care
WARNING: 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.
Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.
Follow the steps below for blade service:
1. Disconnect spark plug wire from spark plug.
2. Tip mower as specified in separate engine manual. If
it does not specify turn mower on its side making sure
that the air filter and the carburetor are up.
3. Remove the bolt and the blade bell support which
hold the blade and the blade adapter to the engine
crankshaft. See Figure 11.
