Read and follow all instructions in this manual before attempting to operate this machine. Failure to comply with these instructions may result in personal injury. When you see this symbol.

HEED ITS WARNING!

Your Responsibility

Restrict the use of this power machine to persons who read, understand and follow the warnings and instructions in this manual and on the machine.

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.

Children

Tragic accidents can occur if operator is not alert to presence of children. Children are often attracted to mower and 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 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 operation instructions and safety rules in this

manual and should be trained and supervised by a parent.

General Operation

1. Read this operator’s manual carefully in its entiret y 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.

2. 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.

3. 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 parent. Only responsible

individuals who are familiar with these rules of safe

operation should be allowed to use this machine.

4. 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. 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.

5. To help avoid blade contact or a thrown object injury,

stay in operator zone behind handles and keep children,

bystanders, helpers and pets at least 75 feet from mower

while it is in operation. Stop machine if anyone enters

area.

6. Always wear safety glasses or safety goggles during opera

tion and while performing an adjustment or repair to protect

your eyes. Thrown objects which ricochet can cause serious

injury to the eyes.

7. Wear sturdy, rough-soled work shoes and close-fitting

slacks and shirts. Shir ts 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.

8. Do not put hands or feet near rotating parts or under cutting

deck. Contact with blade can amputate hands and feet.

9. A missing or damaged discharge cover can cause blade

contact or thrown object injuries.

10. 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.

11. 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 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.

12. Do not operate the mower while under the influence of

alcohol or drugs.

13. Do not engage the self-propelled mechanism on units so

equipped while starting engine.

14. 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.

15. 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.

16. Mow only in daylight or good artificial light. Walk, never run.

17. Stop the blade when crossing gravel drives, walks or roads.

18. If the equipment should start to vibrate abnormally, stop the

engine and check immediately for the cause. Vibration is

generally a warning of trouble.

19. Shut the engine off and wait until the blade comes to a

complete stop before removing the grass catcher or unclog-

ging 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.

20. 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.

21. Muffler and engine become hot and can cause a burn. Do

not touch.

22. Only use parts and accessories made for this machine by

manufacturer. Failure to do so can result in personal injury.

23. If situations occur which are not covered in this manual,

use care and good judgment. Contact your dealer for

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 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:

1. Mow across the face of slopes; never up and down. Exercise

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.

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.

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 indoor 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 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

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 equip ment 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, discon nect 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 adjust

ment while the engine is running.

9. Grass catcher components, discharge cover, and trail

shield are subject to wear and damage which could

expose moving par ts or allow objects to be thrown. For

safety protection, frequently check components and re-

place immediately with original equipment manufacturer’s

(O.E.M.) par ts 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 gover nor setting or over-rev the engine. The governor controls the maximum safe operating speed of the engine.

11. Maintain or replace safety labels, as necessar y.

12. Observe proper disposal laws and regulations. Improper

disposal of fluids and materials can harm the environment.

Replacing Fuse (If Equipped)

The electric starter circuit and battery are protected by a 40 ampere fuse. If the fuse burns out, the electric starter will not operate. If the unit fails to start with the electric starter, perform the following steps to check the fuse inside the battery housing:

1. Open the battery cover as described in Replacing Battery. See Figure 5-6.

2. Remove fuse from socket and inspect as shown in Figure 5-9. If it is burned out, replace with standard automotive 40 ampere fuse.

3. Carefully place wiring back into housing, close battery cover, and fold upper handle back into place.

NOTE: The engine can be started manually if the fuse burns out.

Off-Season Storage

The following steps should be taken to prepare your lawn mower for storage.

• Clean and lubricate mower thoroughly as described in the lubrication instructions.

• We do not recommend the use of a pressure washer or garden hose to clean your unit.

• Refer to engine manual for correct engine storage instructions.

• Coat mower’s cutting blade with chassis grease to prevent rusting.

• 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.

Battery (If Equipped)

The battery must be stored with a full charge. Extended storage of a discharged battery will reduce life and capacity of the battery.
