IMPORTANT

Safe Practices for Pedestrian-controlled Mowers

This cutting 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.

I. GENERAL OPERATION

1. Read, understand, and follow all instructions on

the machine and in the manual(s) before starting.

2. Do not put hands or feet near or under the machine.

Keep clear of the discharge opening at all times.

3. Only allow responsible adults who are familiar

with the instructions to operate this machine.

4. Clear the area of objects such as rocks, wire, toys,

etc., which could be thrown by the blade. Stay

behind the handle when the engine is running.

5. Be sure the area is clear of bystanders before

operating. Stop machine if anyone enters the area.

6. Do not operate machine barefooted or while wearing

sandals. Always wear substantial footwear.

7. Do not pull machine backward unless absolutely

necessary. Always look down and behind

before and while moving backward.

8. Never direct discharged material toward

anyone. Avoid discharging material against

a wall or obstruction. Material may ricochet

back toward the operator. Stop the blade

when crossing gravel surfaces.

9. Do not operate machine without the entire grass

catcher, discharge guard, rear guard, or other

safety protective devices in place and working.

10. Never leave a running machine unattended.

11. Stop the engine and wait until the blade

comes to a complete stop before cleaning

the machine, removing grass catcher,

or unclogging the discharge guard.

12. Operate machine only in daylight

or good artificial light.

13. Do not operate machine while under

the influence of alcohol or drugs.

14. Never operate mower in wet grass. Always

be sure of your footing; walk, never run.

15. Disengage the drive system, if so

equipped, before starting the engine.

16. If the machine should start to vibrate

abnormally, stop the engine and check

for the cause immediately. Vibration is

generally a warning of trouble.

17. Always wear eye protection when

operating machine.

18. See manufacturer’s instructions for proper

operation and installation of accessories. Only

use accessories approved by the manufacturer.

19. The warnings and precautions discussed in this

manual cannot cover all possible conditions and

situations that may occur. It must be understood

by the operator that common sense and caution

are factors which cannot be built into this

product, but must be supplied by the operator.

20. WARNING: This product contains di (2-ethylhexyl)

phthalate (DEHP), a chemical known to the State

of California to cause cancer and birth defects

or other reproductive harm. (California Health

& Safety Code § 25249.5, et seq.)

II. SLOPE OPERATION

Slopes are a major factor related to slip and fall accidents, which can result in severe injury.

Operation on all slopes requires extra caution. If you feel uneasy on a slope, do not mow it.

1. Mow across the face of slopes; never

up and down. Exercise extreme caution

when changing direction on slopes.

2. Watch for holes, ruts, bumps, rocks, or other

hidden objects. Uneven terrain could cause a slip

and fall accident. Tall grass can hide obstacles.

3. Do not mow on wet grass or excessively

steep slopes. Poor footing could

cause a slip and fall accident.

4. Do not mow near drop offs, ditches,

or embankments. You could lose

your footing or balance.

Children are often attracted to the machine and the mowing activity.

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. Never allow children to operate the machine.

4. Use extra care when approaching

blind corners, shrubs, trees, or other objects

that may block your view of a child.

IV. 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.

1. Extinguish all cigarettes, cigars, pipes,

and other sources of ignition.

2. Use only an approved gasoline container.

3. Never remove gas cap or add fuel

with the engine running.

4. Allow engine to cool before refueling.

5. Never refuel the machine indoors.

6. Never store the machine or fuel container where

there is an open flame, spark, or pilot light such

as on a water heater or on other appliances.

7. 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.

8. Remove gas powered equipment from the

truck or trailer and refuel it on the ground.

If this is not possible, then refuel such

equipment with a portable container, rather

than from a gasoline dispenser nozzle.

9. 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.

10. If fuel is spilled on clothing, change

clothing immediately.

11. Never overfill fuel tank. Replace gas

cap and tighten securely.

12. When spills of fuel or oil occur, they must be

cleaned up immediately. Dispose of fluids and

cleaning materials as per any local, state, or

federal codes and regulations. Store oil rags in

a bottom-ventilated, covered, metal container.

13. Do not fill fuel tank to the top.

Leave a little room for the fuel to expand as needed.

14. Wipe up any spilled fuel and allow excess

to evaporate before starting engine.

To prevent FIRE, do not start the engine

while the smell of fuel hangs in the air.

GENERAL SERVICE

1. Never operate machine in a closed area.

2. Keep all nuts and bolts tight to be sure the

Vibration Hazard

This tool vibrates during use. Repeated or

long-term exposure to vibration may cause

temporary or permanent physical injury,

particularly to the hands, arms and shoulders.

To reduce the risk of vibration-related injury:

1. Anyone using vibrating tools regularly or for an

extended period should first be examined by a

doctor and then have regular medical check-

ups to ensure medical problems are not being

caused or worsened from use. Pregnant women

or people who have impaired blood circulation

to the hand, past hand injuries, nervous system

disorders, diabetes, or Raynaud’s Disease should

not use this tool. If you feel any medical or

physical symptoms related to vibration (such as

tingling, numbness, and white or blue fingers),

seek medical advice as soon as possible.

2. Do not smoke during use. Nicotine reduces

the blood supply to the hands and fingers,

increasing the risk of vibration-related injury.

3. Wear suitable gloves to reduce the

vibration effects on the user.

4. Use tools with the lowest vibration when there

is a choice between different processes.

5. Include vibration-free periods each day of work.

6. Grip tool as lightly as possible (while still keeping

safe control of it). Let the tool do the work.

7. To reduce vibration, maintain the tool as

explained in this manual. If any abnormal

vibration occurs, stop use immediately.

Check/Fill Fuel

WARNING! TO PREVENT SERIOUS

INJURY FROM FIRE:

Fill the fuel tank in a well-ventilated area

away from ignition sources. If the engine is

hot from use, shut the engine off and wait

for it to cool before adding fuel. Do not smoke.

1. Clean the Fuel Cap and the area around it.

2. Unscrew and remove the Fuel Cap.

3. Remove the Strainer and remove any dirt

and debris. Then replace the Strainer.

Note: Do not use gasoline containing more than

10% ethanol (E10). Do not use E85 ethanol. Add fuel

stabilizer to the gasoline or the Warranty is VOID.

Note: Do not use gasoline that has been stored in a

metal fuel container or a dirty fuel container. It can

cause particles to enter the carburetor, affecting

engine performance and/or causing damage.

4. If needed, fill the Fuel Tank to about 1 inch under

the fill neck of the Fuel Tank with 87 octane or

higher unleaded gasoline that has been treated

with a fuel stabilizer additive. Follow fuel stabilizer

manufacturer’s recommendations for use.

5. Then replace the Fuel Cap.

6. Wipe up any spilled fuel and allow excess

to evaporate before starting engine.

To prevent FIRE, do not start the engine

while the smell of fuel hangs in the air.

Change Engine Oil

CAUTION! Oil is very hot during operation and can

cause burns. Wait for engine to cool before changing oil.

1. Make sure the engine is stopped and is level.

2. Close the Fuel Valve.

3. Place a drain pan (not included) underneath

the crankcase’s drain plug.

4. Remove the drain plug and, if possible,

tilt the crankcase slightly to help drain

the oil out. Recycle used oil.

5. Replace the drain plug and tighten it.

6. Clean the top of the Dipstick and the area around it.

7. Remove the Dipstick by turning it counterclockwise,

and wipe it off with a clean, lint free rag.
