Engine Controls, To Adjust the Handlebar Height

10Section 3: Features and Controls

Figure 3-2: Depth Regulator Lever.

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

For best results, always begin tilling at a very shallow depth setting and gradually increase the tilling depth.

Complete details on using the Depth Reg- ulator are found in Section 4 of this manual.

WARNING

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

•Place the Depth Regulator Lever in the “travel” position before starting the engine. This position prevents the tines from touching the ground until you are ready to begin tilling.

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

HANDLEBAR HEIGHT ADJUSTMENT

The handlebar height is adjustable to four different settings. When setting the height, keep in mind that the handlebars will be lower when the tines are engaged in the soil.

To Adjust the Handlebar Height:

1.Stop the engine, wait for all parts to stop moving and then disconnect the spark plug wire. Remove the ignition key on electric start models.

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

3.Loosen the height adjustment flange screw (F, Figure 3-3) and pull the keyed washer (E) free of the slots in the curved height adjustment bracket.

4.Move the handlebars to the new slot setting and insert the raised keys on the keyed washer into the slot. Tighten the height adjustment flange screw securely.

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

ENGINE CONTROLS

Refer to the engine manufacturer’s Engine Owner’s Manual (included in the tiller liter- ature package) to identify the controls on your engine.

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

SPECIAL NOTICE REGARDING “MOTOR OIL ALERT SYSTEM”

The engine on your tiller is not equipped with a functioning “Oil Alert System” and you should ignore any references in your Engine Owner’s Manual regarding this feature.

The “Oil Alert System” is not practi- cal for use with your tiller because the engine is frequently operated in non-level applications that would provide false readings to the system’s oil level sensor. These false readings would result in fre- quent, and unnecessary, engine shut downs.

You can easily protect your engine from damage caused by insufficient oil in the crankcase by simply remembering to do the following:

•Check the motor oil level before starting the engine.

•Check the motor oil level after every five (5) hours of continuous operation.
