REVERSECLUTCHCONTROL

The ReverseClutch Control (C, Figure

3-1) controls the engagementof reverse drive to the wheels and tines. The revers-

ing feature is used for maneuveringthe tiller only- never engage the tines in

the groundwhile goingin the reverse direction.

•Use extreme caution when reversing or pulling the machine towards you. Lookbehindto avoidobstacles.

•Never attemptto till in reverse.

Failure to follow this warning could result in personal injury or property damage.

To Operate the Reverse ClutchControl:

1.Put the Wheel GearLever in the

ENGAGEposition (seethe "WARNING" statement on previous page).

2.Stop all tiller motion by releasing the Forward Clutch Control levers.

3.Lift up the handlebars until the tines clear the ground, look behindyou to avoid

any obstacles, and then pull the Reverse Clutch Control knob out. The tines and

wheelswill rotate in a reversedirection.

4.Releasethe ReverseClutch Control

knob to disengage (stop) the wheels and tines. All reversemotion will stop (the enginewill continue to run).

•Do not attempt to till too deeply too quickly. Gradually work down to deeper tilling depths.

•Place the DepthRegulator Lever in the "travel" position before starting the engine. This position prevents the tines from touching the ground until you are ready to begintilling.

Failure to follow this warning could result in personal injury or property damage.

DEPTHREGULATOR

The Depth Regulator lever (D, Figure3-2) controls the tilling depth ofthetines. Pull the lever straight backand slide it up or down to engagethe notched height set- tings.

Figure 3-2: Depth RegulatorLever,

The highest notch (lever all the way down) raises the tines approximately

1-1/2 inches off the ground. This "travel" position allows the tiller to be moved without the tines digging into the ground.

Moving the lever up increasesthe tilling depth. The lowest notch allows a tilling depth of approximately six to eight inches, depending on soil conditions.

Forbest results, always begin tilling at

avery shallow depthsettingand gradu- ally increasethe tilling depth. Complete details on using the Depth Regulatorare found in the "Operation" Section of this manual.

HANDLEBAR HEIGHT ADJUSTMENT

The handlebarheight is adjustableto four

different settings. Set the handlebar

height to a comfortable setting, but keep in mind that the handlebarswill be lower

when the tines are engagedin the soil.

To Adjustthe Handlebar Height:

F

Figure3-3: Handlebarheightadjustment.

1.Stop the engine, wait for all parts to stop moving and then disconnect the

spark plug wire. Removethe ignition key on electric start models.

2.Loosen the two screws at the lower ends of the handlebar.

3.Loosen the height adjustment screw (E, Figure 3-3) and pull the keyedwasher

(F) free of the slots in the curved height adjustment bracket.

4.Move the handlebarsto the new slot

setting and insert the raised keys on the keyedwasher into the slot. Tighten the

height adjustment screw securely.

5.Retightenthe two screws at the ends of the handlebar.

ENGINECONTROLS

Referto the engine manufacturer'sEngine Owner'sManual (included in the tiller lit- erature package)to identify the controls on your engine. The following two con- trols are used when stopping or starting the engine.

IMPORTANT: The control for stopping the recoil start engine is located on the engine.

ENGINE THROTTLE CONTROL LEVER

The EngineThrottleControlLever(located on engine--see Figure4-1) is used to reg- ulatethe engine speed. Onthe recoil start model only, it is also used to stop the engine (on the electric start model,the electric start keyswitch is used to stop the

engine). The throttle settings are shown below.

IMPORTANT: See"Starting and Stopping the Engine" in the "Operation" Sectionfor detailed engine starting and stopping instructions.

,_ FAST- Usefor most tilling and cultivating projects.

,_b_ SLOW- Usewhen idling engine or when slower tilling and cultivating speedsare needed.

_STOP - Stops the engine (on recoil start models only).

ELECTRIC START KEYSWITCH

(MODEL E666M)

The ignition keyswitch on the electric start model is usedto start and stop the engine. The keyswitch settings are described below.

IMPORTANT: See"Starting and Stopping the Engine" in the "Operation" Sectionfor detailed instructions.

OFF -Stops engine.

RUN - After starting, key returns to run position.

START- Starts engine. Releasekeywhen engine starts (avoid cranking enginefor longer than 15 seconds for eachattempt)
