ground.

STEP8: CHECKHARDWARE

Checkall nuts andscrews for tightness.

STEP 9: CHECKAIR PRESSURE IN

TIRES (units with pneumatic tires)

Ontires equipped with air valves, check

theair pressure with atire gauge. Deflate

or inflate the tires equally to between15

PSIand20 PSI(pounds persquareinch).

Besure that both tires are inflated equally

or the unit will pull to one side.

WARNING: Before ReverseClutchControl

operatingyour machine, (Models634F/634B)

carefully readand understand

all safety (Section 1),controls

(Section 3) and operating

instructions (Section 4) inthis

Manual,the separateEngine

decalson the machine.

Failureto follow these

instructions canresult in

serious personalinjury.

INTRODUCTION

Readthis OperationSection and the sepa-

rate EngineOwner's Manualbeforeyou

start the engine. Then,takethe time to fa-

miliarize yourself with the basicoperation

of the tiller beforeusing it in the garden.

Findan open,levelareaand practiceusing

thetiller controls without thetines engag-

ing the soil (put tines in "travel" setting).

Onlyafter you've becomecompletely fa-

miliar with thetiller shouldyoubegin using

it in the garden.

BREAK-INOPERATION

Perform the following maintenanceafter

thefirst two (2) hours of newoperation

(seeMaintenanceSection in this manual

and in the EngineOwner's Manual).

1. Changeengineoil.

2. Checkfor looseor missing hardwareon

unit. Tighten or replaceas needed.

3. Checktension on forward drive belt.

4. Checktransmission gear oil level.

STARTINGANDSTOPPING

Pre-StartChecklist

With the spark plug wire disconnected

from the spark plug,perform thefollowing

checksand services beforeeachuse:

1. Readthe Safetyand ControlsSections

in this manual. Readthe separateEngine

Owner'sManual providedwith the unit.

2. Putthewheels in theWHEELDRIVE

position (wheel pins must be through

holes in wheel hubsand wheel shaft).

3. Checkunit for loose or missing hard-

ware. Serviceas required.

4. Checkengine oil level. SeeEngine

Owner'sManual.

Fig.4-1

5. Checkthat all safetyguardsand covers

are in place.

6. Checkair cleanerand enginecooling

system. SeeEngineOwner'sManual.

WARNING: GASOLINEIS

HIGHLYFLAMMABLEAND ITS

VAPORSAREEXPLOSIVE.

Follow gasolinesafety rules in

this Manual(seeSection1) and

in the separateEngineOwner's

Manual.

Failureto follow gasolinesafety

instructions can result in

serious personalinjury and

property damage.

7. Fillthefueltank with gasolineaccording

to the directions in the separateEngine

Owner'sManual. Followall instructions

and safety rules carefully.

8. Attach spark plug wireto spark plug.

StartingtheEngine

Thefollowing steps describe how to start

and stop the engine.

WARNING: Donotattempt

to engagethetines or wheels

until you havereadall ofthe

operatinginstructions in this

Section. Also, reviewthesafety

rules in Section1: Safety,and

the tiller and enginecontrols

information in Section3:

Featuresand Controls.

1. Completethe Pre-Start Checklist on

this page.

2. Putthe wheelsinthe WHEELDRIVEpo-

sition (seeWheeIDrivePinsinSection 3 of

this manual).

_ ARNING: To help

prevent serious personalinjury

or damageto equipment:

• Beforestartingengine,putbothwheels

in the WHEELDRIVE position. Never

have wheels in FREEWHEELposition

when engine is running. When the

wheels are in FREEWHEEL,they do not

hold backthe tiller and the tines could

propelthetiller rapidly

ward orbackward.

• Before starting engine, put Forward

Clutch Bail (all models) and Reverse

ClutchControl(Models 634F/634Bonly)

in neutral (disengaged) positionsby re-

leasing levers.

• Never run engine indoorsor in en-

closed, poorly ventilated areas. Engine

exhaust contains carbon monoxide, an

odorlessand deadlygas.

• Avoidenginemufflerandnearbyareas.

Temperaturesin theseareas mayexceed

150oF.

3. Movethe Depth RegulatorLeverall the

way down to the "travel" position, sothat

thetines clearthe ground.

4. Releaseall controls on thetiller.

5. On engine'swith a fuel shut-off valve,

turn valve to open position, as instructed

in the separateEngineOwner's Manual.

6. Putignition switch and/or throttle con-

trol leverlocated on engine in the "ON",

"RUN", "FAST"or "START"position, as in-

structed in the EngineOwner's Manual.

7. Chokeor prime engine,asinstructed in

8. Putone handon fuel tankto stabilize

unit when pulling starter rope handle.

Thenuserecoil starter to start engine,as

instructed in the EngineOwner's Manual.

Whenenginestarts, graduallymove choke

lever (if so equipped) to "NOCHOKE",

Stoppingthe EngineandTiller

1. Tostop thewheelsandtines, releasethe

ForwardClutch Bail(all models) or the Re-

2. Tostop theengine, putthe ignition

OPERATINGTHETILLER

Thefollowing operating instructions pro-

videguidelines to usingyour tiller effec-

tively and safely. Besureto read Tilling

Tips& Techniquesin this Section before

actually putting the tines into the soil.

NOTE:This isa traditional "Standard-Ro-

tating-Tine" (SRT)tiller with forward ro-

tating tines. It operatescompletely

differently from "Counter-Rotating-Tine"

(CRT)tillers or from front-tine tillers.

1. Followthe Pre-Start Checklist at the

beginning ofthis Section. Besurethat the

wheelsare in theWHEELDRIVEposition.

2. Movethe Depth RegulatorLeverall the

way down, sothat thetines clearthe

ground. Usethis position whenpracticing

with thetiller and when traveling between

tilling sites. Beforeactuallytilling, move

the leverto the desireddepth setting (see

Tilling Tips & Techniques).

3. Start engine and allow itto warm up.

Thenput throttle in "FAST"setting.

4. For forwardmotion of the wheels and

tines:

(a) Pull ForwardClutch Bail (Fig.4-1) up

againsthandlebar. Releasebailto stopfor-

ward motion of wheels andtines.

(b) Whentilling, relaxand letthe wheels

pull the unit while thetines dig. Walk be-

hindand a little to onesideofthe unit. Use

one hand,yet keepalight--but secure--

grip on the handlebar(while keepingyour

arm loose). SeeFig.4-2. Let the unit

move at its own paceand do not push

down on the handlebarsto try and force

thetines todig deeper--this takesweight

off the wheels,reduces traction, and caus-

esthe tines to try and propel the tiller.

WARNING: Donot push

down onthe handlebarsto try

to makethetiller till more

deeply. This preventsthe

wheelsfrom holdingthetiller

backand canallow thetines to

rapidly propelthetiller forward,

which could result in loss of

control, property damage,or

personalinjury.

5. For reversemotion of the wheelsand

tines (Models 634F/634Bonly):

(a) Lookbehindandexercisecaution when

operating in reverse. Donottill while in

reverse.

(b) Stopall forward motion. Lift handle-

bar with one handuntil tines are off the

ground and then pull ReverseClutchCon-

trol knobout (seeFig.4-3). Tostop revers-

ing, let go of ReverseClutch Control knob.

(b) Swingthe handlebarto the left sothe

swing the handlebarto the right so theleft

wheel"steps" backward.Repeatasneeded.

AIRCLEANERSERVICE

Theair cleanerfilters dirt and dust out of

theair before it enters the carburetor. Op-

ENGINEOILSERVICE

Checkthe engineoil levelbeforeeachuse

andafter everyfive hours of continuous

operation. Running theengine when it is

low on oil will quickly ruin theengine.

It is recommendedthat youchangethe

motor oil after every 10hours of operation

and evensoonerwhen operating in ex-

tremelydirty or dusty conditions. Referto

the EngineOwner'sManualfor detailed

service instructions.

A. ToChecktheEngineOil Level:

1. Parkthe tiller on a levelareaand shut

off the engine.

2. Levelthe engine(usethe Depth Regu-

lator Leverto adjust the engineangle).
