I. GENERALOPERATION

1. Read, understand, and follow all instructionson the

machine and in the manuals. Be thoroughly familiar

with the controls and the proper use of the mower

before starting.

2. Do not put hands or feet near or under rotatingparts.

Keep clear of the mower blade and discharge open-

ing at all times.

3.' Only allow responsible individuals, who are familiar

with the instructions, to operate the mower.

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

bones, sticks, etc., which could be picked up and

thrown by the blade.

5. Be sure the area is clear of other people before

mowing. Stop mower if anyone enters the area.

Keep bystanders at least 25 feet away from the area

of operation.

Do not operate the mower when barefoot or wearing

open sandals. Always wear substantial foot wear.

Do not pull mower backwards unless absolutely nec-

essary. Look down and behind before and while

moving backwards.

10.

11.

Do not operate the mower without proper guards,

plates, grass catcher or other safety protective de-

vices in place.

Refer to provided instructionsfor proper operation

and installation of accessories. Only use acces-

sories approved by Sears, Roebuck and Co.

Stop the blade when crossing gravel drives, walks,

or roads.

Stop the engine and disconnect the spark plug wire

from the spark plug whenever you leave the unit, be-

fore cleaning the mower or unclogging the chute.

12. Shut the engine off, wait until the blade comes to a

complete stop, and disconnect the spark plug wire

before installing or removing the mulcher cover or

the optional grass catcher. Make certain that the

grass catcher is securely attached before operating

the mower. Empty the grass catcher after each use-

decomposing debris could generate enough heat to

catch fire.

13. Mow in daylight or good artificial light.

14. Do not operate the mower while under the influence

of alcohol or drugs.

15. Never operate mower in wet grass. Always be sure of

your footing; keep a firm hold on the handle and walk;

SAFETY RULES

18. Always wear safety goggles or safety glasses with

side shields when operating mower.

19. Watch for traffic when operating near, or when cross-

ing roadways.

20. Never attempt to carry children or other passengers

on the mower. They could fail off and be seriously in-

jured, or they could interfere with the safe operation

of the mower.

21. Check the operation of the Operator Presence Con-

trol before each use. See the Customer Responsibili-

ties Section of this manual for instructions. Ifthe

mower blades rotate longer than three seconds after

the Operator Presence Control is released, the sys-

tem is not working properly. Immediately contact

your local Sears Service Center/Department for in-

structions. Do not use the mower until the mecha-

nism is repaired.

22. The mower is equipped with a safety discharge

chute, comes with a special mulcher cover and offers

an optional grass catcher. The safety discharge

chute must be working properly at all times. Never

attempt to disconnect or otherwise cause this dis-

charge chute to cease working. If used, mulcher

cover or grass catcher attachment must be installed

properly and function correctly. Do not use your

equipment otherwise.

23. Never runthe engine in an enclosed area. Engine ex-

haust contains carbon monoxide, a deadly gas that is

ododess, colodess, and tasteless. Always runthe en-

gine outdoors and make sure there is adequate

ventilation.

II. SLOPEOPERATION

Slopes are a major factor related to slip and fall acci-

dents which can result in severe injury. All slopes

require extra caution. If you feel uneasy on a slope,

do not mow it.

DO:

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

Exercise extreme caution when changing direction on

slopes. Avoid slopes greater than 15o.

Remove objects such as recks, tree limbs, etc.

Watch for holes, ruts, or bumps. Tall grass can hide

obstacles.

DO NOT:

Do not mow near drop-offs, ditches, or embankments.

The operator could loose footing or balance.

Do not mow excessively steep slopes.

Do not mow on wet grass. Reduced footing could

cause slipping.

III. CHILDREN

Tragic accidents can occur if the operator is not alert

to the presence of children. Children are often at-

tracted to the mower and to 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.

2. Be alert and turn mower off ifchildren enter the area.

3. Before and while moving backwards, look behind

and down for small children.

4. Never allow children to operate the mower.

5. Use extra care when approaching blind comers,

shrubs, trees, or other objects that may obscure

vision.

IV.SERVICE

They are flammable and their vapors are explosive.

a) Use only an approved container.

b) Never remove gas cap or add fuel when the en-

gine is-running.Allow engine to cool before refu-

eling. Do not smoke.

c) Never refuel the machine indoors.

d) Never store the machine or fuel container inside

where there is an open flame, such as a water

heater, etc.

e) Move mower away from any gasoline fumes be-

fore starting the engine.

Never run an engine inside a closed area.

Never make adjustments or repairs with the engine

running. Disconnect the spark plug wire and keep

the wire away from the plug to prevent accidental

ment bolts, tight and keep equipment in good condi-

tion.
