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 machine on a sloped or
hilly area. If the slope is greater than 15 degrees, do not mow it.

Service

SafeHandling OfGas01ine:

I. 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 engine is hot or
running. Allow engine to cool at least two minutes before

refueling.

9. Never overfill fuel tank. Filltankto no more than I inch
below bottom of filler neck to provide for fuel expansion.

I0. Replace gasoline cap and tighten securely.
1I. If gasoline is spilled, wipe it off the engine and equipment.

Move machine to another area. Wait 5 minutes before
starting 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 machine free of grass, leaves,
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel soaked debris.

14. Allow machine to cool at least 5 minutes before storing.

GeneralService:

I. 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's governor setting or over-speed
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 and instruction labels, as
necessary.

14. Observe proper disposal laws and regulations. Improper
disposal of fluids and materials can harm the environment.

15. According to the Consumer Products Safety Commission
(CPSC) and the U.S. Environmental Protection Agency (EPA),

this product has an Average Useful Life of seven (7) years,
or 140 hours of operation. At the end of the Average Useful
Life have the machine inspected annually by an authorized
service dealer to ensure that all mechanical and safety

systems are working properly and not worn excessively.
Failure to do so can result in accidents, injuries or death.

Donot 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.

Maintenance&Adjustments

Maintenance

GeneralRecommendations

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 lawn mower as instructed here.

Changing of engine-governed speed will void engine
wa rra nty.

All adjustments should be checked at least once each
season.

Periodically check all fasteners and make sure these are
tight.

WARNING: Always stop engine, disconnect spark

plug, and ground against engine before performing

any type of maintenance on your machine.

Lubrication

1. Lubricate pivot points on the blade control at least once
a season with light oil. This control must operate freely in

both directions. See Fig. 6-1.

2. Lubricate the wheels at least once a season with light oil (or
motor oil). If wheels are removed for any reason, lubricate
surface of the pivot arm and inner surface of the wheel

with light oil. See Fig. 6-1.

3. Lubricate the torsion spring and pivot point on the rear
discharge door and side mulch plug periodically with light
oil to prevent rust. See Fig. 6-1.

4. Follow the Engine Maintenance section for lubrication
schedule and instruction for engine lubrication.

DeckCare

Clean underside of the mower deck after each use to prevent
build-up of grass clippings or other debris. Follow steps below

for this job.

1. Disconnect spark plug wire. Drain gasoline from lawn
mower or place a piece of plastic under the gas cap.

2. Tip mower so that it rests on the housing. Keep the side
with the air cleaner facing up. Hold mower firmly.

any direction and do not leave the mower tipped for

WARNING: Never tip the mower more than 90° in

any length of time. Oil can drain into the upper part

of the engine causing a starting problem.

3. Scrape and clean the underside of the deck with a suitable
tool. Do not spray with water.

IMPORTANT: Do not use a pressure washer or garden hose
to clean your unit. These may cause damage to the engine.

The use of water will result in shortened life and reduce
serviceability.

4. Put the mower back on its wheels on the ground. Ifyou
had put plastic under the gas cap earlier, make sure to
remove it now.

EngineCare

NOTE: Refer to the engine operation and maintenance sections
in this manual for detailed instructions.

Maintain oil level.
Service air cleaner every 100 hours or once a season under

normal conditions. Clean more frequently under extremely
dusty conditions.

Clean spark plug and reset the gap once a season.
Clean engine regularly with a cloth or brush. Keep the area

around the top of the engine clean to permit proper air
circulation. Remove all grass, dirt, and combustible debris
