SAFE OPERATION PRACTICES FOR WALK-BEHIND MOWERS

TRAINING

1. Read this owner’s manual carefully in its en tirety before attempting to assembie or operate this machine. Be completeiy familiar with the controls and the proper use of this machine before operating it. Keep this manuai in a safe place for future and regular reference and for ordering replacement parts.

2. Your rotary mower is a precision piece of power equipment, not a plaything. Therefore, exercise extreme caution at all times.

3. Never allow children to operate a power

mower. Only persons well acquainted with

these rules of safe operation should be al

lowed to use your mower.

4. Keep the area of operation clear of all per sons, particularly small children and pets. Stop engine when they are in the vicinity of your mower. Although the area of operation should be completely cleared of foreign ob jects, an object may have been overlooked and could be accidently thrown by the mower

in any direction and cause serious personal injury to the operator or any others allowed in

the area.

PREPARATION

1. Thoroughly inspect the area where the equip

ment is to be used. Remove all stones, sticks,

' wire, bones and other foreign objects which

could be picked up and thrown by the mower

in any direction and cause serious personal injury to the operator or any others allowed in

the area.

2. Do not operate equipment when barefoot or wearing open sandals. Always wear substan tial footwear.

3. Do not wear loose fitting clothing that could get caught on the mower.

4. Check the fuel before starting the engine. Gasoline is an extremely flammable fuel. Do

not fill the gasoline tank indoors, while the

engine is running, or while the engine is still

hot. Wipe off any spilled gasoline before start ing the engine as it may cause a fire or explo

sion.

5. Disengage the self-propelled mechanism or drive clutch on units so equipped before start

ing the engine.

6. 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 han dle must operate easily in both directions.

7. Never attempt to make a wheel or cutting height adjustment while the engine is run ning.

N 8. Mow only in daylight or in good artificial light.

9. Never operate the equipment in wet grass. Always be sure of your footing. A slip and fall can cause serious personal injury. Keep a firm

hold on the handle and walk, never run.

OPERATION

1. Do not change the engine governor settings or overspeed the engine. Excessive engine speeds are dangerous.

2. Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times as the rotating blade can cause in jury.

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

4. After striking a foreign object, stop the engine, remove the wire from the spark plug, and thoroughly inspect the mower for any damage. Repair the damage before restarting and operating the mower.

5. If the equipment should start to vibrate abnor

mally, stop the engine and check immediately

for the cause. Vibration is generally a warning of trouble.

6. 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 un til you are sure the blade has stopped rotating.

7. Before cleaning, repairing or inspecting, make

certain the blade and all moving parts have stopped. Disconnect the spark plug wire, and keep the wire away from the spark plug to pre

vent accidental starting.

8. Do not run the engine indoors.

9. Mow across the face of slopes, never up-and-

down. Exercise extreme caution when chang ing direction on slopes. Do not mow ex cessively steep slopes. Always be sure of your footing. A slip and fall can cause serious personal injury.

10. Always disconnect electric mowers (line

operated) before cleaning, repairing or ad justing.

11. Never operate mower without proper guards, plates or other safety protective devices in

place.

MAINTENANCE AND STORAGE

1. Check the blade and engine mounting bolts at

frequent intervals for proper tightness.

2. Keep all nuts, bolts, and screws tight to be

sure the equipment is in safe working condi tion.

3. Never store the equipment with gasoline in the tank inside of a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any en closure.

4. To reduce fire hazard, keep the engine free of grass, leaves, or excessive grease.

5. Check the grass catcher bag frequently for wear or deterioration. For safety protection, replace only with new bag meeting original

equipment specifications.

NOTE

This unit is'shipped WITHOUT GAS OLINE or OIL. After assembly, see separate engine manual for proper fuel and engine oil recommenda tions.
