SAFE OPERATION PRACTICES FOR WALK-BEHIND MOWERS

TRAINING

1. It is suggested that this manual be read in its entirety before attempting to assemble or operate this unit. Keep this manual in a safe place for future reference and for ordering replacement parts. Your rotary mower is a precision piece of

power equipment, not a plaything. Therefore, exercise extreme caution at all times.

Read this Owner’s Manual carefully. Be

3. thoroughly familiar with the controls and the

proper use of the equipment. 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. Keep the area of operation clear of all per

5. 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, a small object may have been over

looked and could be accidently thrown by the mower in any direction and cause injury.

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 injury. Do not operate equipment when barefoot or

wearing open sandals. Always wear substan tial footwear. Do not wear loose fitting clothing that could

get caught on the mower. 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. Disengage the self-propelled mechanism or

5. drive clutch on units so equipped before start

ing the engine.

Never attempt to make a wheel or cutting

height adjustment while the engine is run

ning. Mow only in daylight or in good artificial light.

Never operate the equipment in wet grass.

Always be sure of your footing. Keep a firm

hold on the handle and walk, never run.

OPERATION

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

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. Stop the blade when crossing gravel drives,

walks or roads.

After striking a foreign object, stop the

4. 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. 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. Stop the engine whenever you leave the

mower, before cleaning the mower housing, and when making any repairs or inspections. When 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 plug to prevent accidental starting.

Before attempting to unclog the mower or

discharge chute, stop the engine and be sure the blade has stopped completely. The cut ting 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.

Disconnect the spark plug wire and keep the wire away from the plug to prevent accidental starting.

Do not run the engine indoors.

9. Shut the engine off and wait until the blade

10.

comes to a complete stop before removing the grass catcher or unclogging chute.

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

11.

down. Exercise extreme caution when chang

ing direction on slopes. Do not mow ex cessively steep slopes. Always disconnect electric mowers (line

12.

operated) before cleaning, repairing or ad justing.

Never operate mower without proper guards,

13. plates or other safety protective devices in place. Keep washout ports and other mower-housing

14. service openings closed when mowing.

MAINTENANCE AND STORAGE
