I. GENERAL OPERATION

• Read, understand, and follow all instructions on the machine and in the

manual(s) before starting. Be thoroughly familiar with the controls and the proper

use of the machine before starting.

• Do not put hands or feet near or under rotating parts. Keep clear of the dis-

charge opening at all times.

• Only allow responsible individuals, who are familiar with the instructions, to oper-

ate the machine.

• Clear the area of objects such as rocks, toys, wire, bones, sticks, etc., which could be picked up and thrown by the

blade.

• Be sure the area is clear of other people before mowing. Stop machine if anyone

enters the area.

• Do not operate the mower when bare- foot or wearing open sandals. Always

wear substantial foot wear.

• Do not pull mower backwards unless absolutely necessary. Always look down and behind before and while moving

backwards.

• Do not operate the mower without proper guards, plates, grass catcher or other safety protective devices in place.

• See manufacturer's instructions for proper operation and installation of

accessories. Only use accessories ap- proved by the manufacturer.

• Stop the blade(s) when crossing gravel drives, walks, or roads.

• Stop the engine (motor) whenever you leave the equipment, before cleaning the

mower or unclogging the chute.

• Shut the engine (motor) off and wait until the blade comes to complete stop before removing grass catcher.

• Mow only in daylight or good artificial light.

• Do not operate the machine while under the influence of alcohol or drugs.

• Never operate machine in wet grass. Always be sure of your footing: keep a

firm hold on the handle and walk; never run.

• Disengage the self-propelled mech- anism or drive clutch on mowers so

equipped before starting the engine (motor).

• If the equipment should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibra- tion is generally a warning of trouble.

• Always wear safety goggles or safety glasses with side shields when operating

mower.

II. SLOPE OPERATION Slopes are a major factor related to slip

and fall accidents which can result in severe injury. All slopes require extra cau- tion. 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.

• Remove obstacles such as rocks, tree limbs, etc.

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

DO NOT:

• Do not trim near drop-offs, ditches or embankments. The operator could lose

footing or balance.

• Do not trim excessively steep slopes.

• Do not mow on wet grass. Reduced foot- ing could cause slipping.

III. CHILDREN Tragic accidents can occur if the operator

is not alert to the presence of children.

Children are often attracted to the machine and the mowing activity. Never assume

that children will remain where you last saw them.

• Keep children out of the trimming area and under the watchful care of another

responsible adult.

• Be alert and turn machine off if children enter the area.

• Before and while walking backwards, look behind and down for small children.

• Never allow children to operate the ma- chine.

• Use extra care when approaching blind corners, shrubs, trees, or other objects

that may obscure vision.

IV. SERVICE

• Use extra care in handling gasoline and other fuels. They are flammable and

vapors are explosive.

- Use only an approved container.

- Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling.

Do not smoke.

- Never refuel the machine indoors.

- Never store the machine or fuel

container inside where there is an open flame, such as a water heater.

• Never run a machine inside a closed area.

• Never make adjustments or repairs with the engine (motor) running. Disconnect the

spark plug wire, and keep the wire away

3 from the plug to prevent accidental starting.

• Keepnutsandbolts,especiallyblade attachmentbolts,tightand keepequip- mentingood condition.

HOWTO USEYOUR LAWN MOWER ENGINE SPEED The engine speed was set at the factory

for optimum performance. Speed is not adjustable.

ENGINE ZONE CONTROL

• I,CAUTION: Federal regulations require an engine control to be installed on this

lawn mower in order to minimize the risk of blade contact injury. Do not under

any circumstances attempt to defeat the function of the operator control. The blade

turns when the engine is running.

• Your lawn mower is equipped with an

operator presence control bar which

requires the operator to be positioned

behind the lawn mower handle to start and operate the lawn mower.

BEFORE STARTING ENGINE

ADD OIL

Your lawnmower is shipped without oil in the engine. For type and grade of oil to

use, see "ENGINE" in the Maintenance section of this manual.

A CAUTION: DO NOT overfill engine with

oil, or it will smoke heavily from the muffler on startup.

1. Be sure lawnmower is level and area around oil fill is clean.

2. Remove engine oil plug and fill to the top slot in filler hole. Pour oil slowly.

NOTE: Allow oil to settle down into engine for accurate reading.

3. Reinstall engine oil plug and tighten.

IMPORTANT:

• Check oil level before each use. Add oil

if needed. Fill to top slot in filler hole.

• Change the oil after every 25 hours of

operation or each season. You may

need to change the oil more often under dusty, dirty conditions. See "TO

CHANGE ENGINE OIL' in the Mainte-

nance section of this manual.

TO ADJUST CUTTING HEIGHT

Raise wheels for low cut and lower wheels for high cut, adjust cutting height to suit

your requirements. Medium position is best for most lawns.

• To change cutting height, squeeze ad- juster lever toward wheel. Move wheel

up or down to suit your requirements. Be sure all wheels are in the same set-

ting.

NOTE: Adjuster is properly positioned when plate tab inserts into hole in lever.

Also, 9-position adjusters (if so equipped) allow lever to be positioned between the plate tabs.

ADD GASOLINE

• Fill fuel tank to bottom of tank filler neck. Do not overfill. Use fresh, clean, regular

unleaded gasoline with a minimum of 87

octane. Do not mix oil with gasoline. Pur- chase fuel in quantities that can be used

AqLwithin30 days to assure fuel freshness.

CAUTION: Wipe off any spilled oil or

fuel. Do not store, spill or use gasoline near an open flame.

A CAUTION: Alcohol blended fuels

(called gasohol or using ethanol or metha- nol) can attract moisture which leads to

separation and formation of acids during storage. Acidic gas can damage the fuel

system of an engine while in storage. To avoid engine problems, the fuel system

should be emptied before storage of 30 days or longer. Empty the gas tank, start

the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel

next season. See Storage Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

TO STOP ENGINE

• To stop engine, release operator pres-

ence control bar.

TO START ENGINE

NOTE: Due to protective coatings on the

engine, a small amount of smoke may be

present during the initial use of the prod-

uct and should be considered normal.

1. To start a cold engine, push primer three (3) times before trying to start.

Use a firm push. This step is not usually necessary when starting an engine which has already run for a few

minutes.

2. Hold operator presence control bar down to the handle and pull starter handle quickly. Do not allow starter rope to snap back.

NOTE: In cooler weather it may be neces- sary to repeat priming steps. In warmer weather over priming may cause flooding and engine will not start. If you do flood engine, wait a few minutes before attempt-

ing to start and do not repeat priming steps.

MOWING TIPS

CAUTION: Do not use de-thatcher

blade attachments on your mower. Such attachments are hazardous, will damage

your mower and could void your warranty.

• Under certain conditions, such as very tall grass, it may be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of grass clip-

pings. It may also be necessary to re-

duce ground speed and/or run the lawn

mower over the area a second time.

• For extremely heavy cutting, reduce the width of cut by overlapping previously cut path and mow slowly.

• For better grass bagging and most cut- ting conditions, the engine speed should

be set in the FAST position.

• For side discharge lawn mowers, cutting

in a counter-clockwise direction, start- ing at the outside of the area to be cut,

spreads grass clippings more evenly and puts less load on the engine. To

keep clippings off of walkways, flower beds, etc., make the first cuts in a clock-

wise direction.

• Pores in cloth grass catchers can be- come filled with dirt and dust with use

and catchers will collect less grass. To

prevent this, regularly hose catcher off

with water and let dry before using.

• Keep top of engine around starter clear and clean of grass clippings and chaff. This will help engine air flow and extend engine life.

periodically to properly maintain your unit.

At least once a season, check to see if you should make any of the adjustments

described in the Service and Adjustments section of this manual.

• At least once a year, replace the spark plug, clean or replace air filter element and check blade for wear. A new spark plug and clean/new air filter element assure proper air-fuel mixture and help your engine run better and last longer.

• Follow the maintenance schedule in this manual.

BEFORE EACH USE

• Check engine oil level.

• Check for loose fasteners.

TO SHARPEN BLADE NOTE: We do not recommend sharpening

blade - but if you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced. An unbalanced blade will

cause eventual damage to lawn mower or engine.

• The blade can be sharpened with a file or on a grinding wheel. Do not attempt

to sharpen while on the mower.

• To check blade balance, drive a nail into a beam or wall. Leave about one inch of

the straight nail exposed. Place center

hole of blade over the head of the nail. If blade is balanced, it should remain in

a horizontal position. If either end of the

blade moves downward, sharpen the heavy end until the blade is balanced.

GRASS CATCHER

(If purchased as an accessory)

• The grass catcher may be hosed with water, but must be dry when used.

• Checkyour grass catcher often for damage or deterioration. Through normal use it will

wear. If catcher needs replacing, replace only with approved replacement catcher

shown inthe Repair Parts section of this

manual. Give the lawn mower model number when ordering.

ENGINE LUBRICATION

NOTE: Although multi-viscosity oils (5W30,

10W30 etc.) improve starting in cold weather, they will result in increased oil consumption when used above 32°E Check your engine

oil level more frequently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of operation orat least once a year if the lawn

mower is not used for 25 hours in one

year.

Check the crankcase oil level before starting the engine and after each five (5)

hours of continuous use. Tighten oil plug securely each time you check the oil level.

TO CHANGE ENGINE OIL

1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

2. Be sure lawn mower is on level surface. NOTE: Oil will drain more freely when

warm. Catch oil in a suitable container.

3. Remove bottom oil drain plug.

3. Clean the inside of the cover and the collar to remove any dirt accumulation.

4. Insert new filter into cover.

5. Put air filter cover and filter into collar aligning the tab with the slot.

2. Remove filter from inside of cover.

SPARK PLUG Replace spark plug at the beginning of

each mowing season or after every 100

hours of operation, whichever occurs

first. Spark plug type and gap setting are shown in the "PRODUCT SPECIFIC-

ATIONS" section of this manual.

CLEANING

IMPORTANT: For best performance, keep

mower housing free of built-grass and

trash. Clean the underside of your mower after each use.

•II,CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

• Clean the underside of your lawn mower by scraping to remove build-up of grass

and trash.

• Clean engine often to keep trash from accumulating. A clogged engine runs hotter and shortens engine life.

• Keep finished surfaces and wheels free of all gasoline, oil, etc.

• We do not recommend using a garden hose to clean lawn mower unless the

electrical system, muffler, air filter and carburetor are covered to keep water

out. Water in engine can result in short- ened engine life.
