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 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 gener
ally 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 tor a few seconds after the
blade control is released. 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 trail shield, discharge cover,
grass catcher, blade control handle or other safety protective de
vices in place and working. Never operate mower with damaged
safety devices. Failure to do so can result in personal injury.

• 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.
• If situations occur which are not covered in this manual, use care
and good judgement. Contact 1-800-659-5917 for information and
assistance.
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 Guide included as part of this manual to measure slopes before
operating this machine 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
extreme caution when changing direction on slopes.
• Watch for holes, ruts, rocks, hidden objects, or bumps which can
cause you to slip or trip. Tall grass can hide obstacles.
• 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 three (3) seconds.
Do Not:
• Do not mow near drop-offs, ditches or embankments, you could
lose your footing or balance.
• Do not mow slopes greater than 15 degrees as shown on the
slope gauge.
• Do not mow on wet grass. Unstable footing could cause slipping.
CHILDREN
Tragic accidents can occur it 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.
• Keep children out of the mowing area and under watchful care of
a responsible adult other than the operator.
• Be alert and turn mower off if a child enters the area.
• Before and while moving backwards, look behind and down for
small children.
• 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.
• Keep children away from hot or running engines. They can suffer
burns from a hot muffler.
• Never allow children under 14 years of age to operate this
machine. Children 14 and over should read and understand the
instructions and safe operation practices in this manual and on
the machine and be trained and supervised by an adult.
SERVICE
Safe Handling Of Gasoline:
• 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.
• 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.
• 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.

SERVICE AND MAINTENANCE
Awarning
Always stop engine, disconnect spark plug wire, and ground against
engine before performing any type of maintenance on your machine.
GENERAL RECOMMENDATIONS
• Always observe safety rules when performing any maintenance.
• 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 equipment as
instructed here.
• Changing of engine-governed speed will void engine warranty.
• All adjustments should be checked at least once each season.
• Periodically check all fasteners and make sure these are tight.
ENGINE MAINTENANCE Spark Plug
NOTE: Incorrect spark plugs can cause engine damage.
For good performance, the spark plug must be properly gapped and
free of deposits. Check the spark plug every 50 hours or once a
season. Replace the spark plug every 200 hours of operation.
1. Disconnect the cap from the spark plug, and remove any dirt from
the spark plug area.
2. Use the proper size spark plug wrench to remove the spark plug.
3. Inspect the spark plug. Replace it it damaged, badly fouled, it the
sealing washer is in poor condition, or if the electrode is worn.
4. Measure the electrode gap with a suitable gauge. The correct gap
is 0.028 - 0.030 in. (0.70 - 0.80 mm). See Figure 12. If adjustment
is needed, correct the gap by carefully bending the side electrode.
5. Install the spark plug carefully, by hand, to avoid cross-threading.
6. After the spark plug is seated, tighten with the proper size spark
plug wrench to compress the washer.
When installing a new spark plug, tighten 1/2 turn after the spark plug
seats to compress the washer.
When reinstalling the original spark plug, tighten 1/8-1/4 turn after the
spark plug seats to compress the washer.
NOTE: Properly tighten the spark plug. A loose spark plug can become
very hot and can damage the engine. Overtightening the spark plug
can damage the threads in the cylinder head.
7. Attach the spark plug cap to the spark plug.
Air Cleaner
A dirty air cleaner will restrict airflow to the carburetor and cause poor
engine performance. Inspect the filter each time the engine is oper
ated. You will need to clean the filter more frequently it you operate the
engine in very dusty areas.
Clean the air cleaner every 25 hours of operation or once a season.
Replace the air cleaner every 200 hours of operation.
NOTE: Operating the engine without a filter, or with damaged filter, will
allow dirt to enter the engine, causing rapid engine wear.
Inspection
1. Press the latch tabs on the top of the air cleaner cover, and
remove the cover. Check the filter to be sure it is clean and in
good condition. See Figure 13.
2. Reinstall the filter and air cleaner cover.
Cleaning
Tap the filter several times on a hard surface to remove dirt, or
blow compressed air not exceeding 30 psi through the filter from
the clean side that faces the engine. Never try to brush off dirt.
Brushing will force dirt into the fibers.
Wipe dirt from the air cleaner body and cover using a moist rag.
Be careful to prevent dirt from entering the air duct that leads to
the carburetor.

SERVICE AND MAINTENANCE
Check Engine Oil
Check oil level before each operation. Be sure oil level is maintained.
1. Check the oil with the engine stopped and level.
2. Remove the oil filler cap/dipstick and wipe It clean.
3. Insert the oil filler cap/dipstick into the oil filler neck as far as It will
go, but do not screw It in, then remove It to check the oil level.
4. If the oil level is near or below the lower limit mark on the dipstick,
remove the oil filler cap/dipstick, and fill with the recommended oil
to the upper limit mark. Do not overfill.
5. Reinstall the oil filler cap/dipstick.
Change Engine Oil
Change engine oil after the first month or five hours of operation, and
every fifty hours or once a season thereafter.
Drain the engine oil when the engine is warm. Warm oil drains quickly
and completely.
1. Turn the fuel valve (Fig. 11) to the OFF position to reduce the
possibility of fuel leakage.
2. Place a suitable container next to the engine to catch the used oil.
3. Remove the oil filler cap/dipstick and drain the oil into the
container by tipping the engine toward the oil filler neck. See
Figure 14.

OFF-SEASON STORAG
Awarning
Never store lawn mower with fuel in tank indoors or in poorly
ventilated areas where fuel fumes may reach an open flame, spark,
or pilot light as on a furnace, water heater, clothes dryer, or gas
appliance.
I
PREPARING THE ENGINE
Fuel in tank can become stale when equipment is stored over 30 days.
Stale fuel causes acid and gum deposits to form in fuel system or on
essential carburetor parts.
To Prevent Fuel-Related Problems:
1. Add gasoline stabilizer following the manufacturer's instructions.
When adding a gasoline stabilizer, fill the fuel tank with fresh
gasoline. If only partially filled, air in the tank will promote fuel
deterioration during storage. If you keep a container of gasoline
for refueling, be sure that it contains only fresh gasoline.
2. After adding a gasoline stabilizer, run the engine outdoors tor
10 minutes to be sure that treated gasoline has replaced the
untreated gasoline in the carburetor.
3. Turn the fuel valve to the OFF position.
4. Continue to run the engine until it stops from the lack of fuel in the
carburetor fuel bowl. Running time should be less than 3 minutes.
IMPORTANT: If fuel stabilizer is not used, you need to drain gasoline
from equipment prior to storage. Run engine until it stops from a lack
of fuel.
Perform the following before long-term storage of equipment:
1.
While engine is still warm, change oil.
2.
Remove spark plug and pour approximately 1/2 oz. (15 ml) of
new engine oil into spark plug cavity which puts oil into cylinder.
Replace spark plug securely.
3.
Pull starter rope slowly. This turns the engine’s crankshaft and
distributes oil through the engine.
4.
Add fuel stabilizer or drain fuel from engine.
5.
Clean dirt and debris from top and all areas around engine.
Store in a clean, dry area.
6.
PREPARING THE LAWN MOWER
• Clean and lubricate mower thoroughly as described in the lubrica
tion instructions.
• Do not use a pressure washer or garden hose to clean your unit.
• Coat mower’s cutting blade with chassis grease to prevent
rusting.
• Refer to PREPARING THE ENGINE for correct engine storage
instructions.
• Store mower in a dry, clean area. Do not store next to corrosive
materials, such as fertilizer.
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 of your lawn mower before storage.
