Disconnect the spark plug wire and move it away from the spark plug to prevent accidental starting. Engage and release the tine engagement handle, then the reverse tine engagement lever (model series 390 only).

Depth Stake Tines And End Caps The depth stake controls the tilling depth. Refer to OPERATING YOUR TILLER in Section 4. The tilling tines and end caps (are used to cultivate, furrow, and prepare your garden for seeding. The end caps (Model Series 390 only) are used to avoid tilled soil from overflowing onto unwanted areas.
• • Removing End Caps (Model Series 390 only) Stand at side of tiller. Grasp the starter handle and pull out slowly, until it pulls slightly harder. Let rope rewind slowly. Pull rope with a rapid full arm stroke. Do not allow handle to snap back. Allow it to rewind slowly while keeping a firm hold on the starter handle. The end cap, which are used to avoid tilled soil from overflowing onto unwanted areas, are removable from the outer axle.
Handle Pressure Transport Position Further control of tilling depth and travel speed can be obtained by variation of pressure on the handles. • A downward pressure on the handles will reduce the working depth and increase the forward speed. • An upward pressure on the handles will increase the working depth and reduce the forward speed. The type of soil and working conditions will determine the actual setting of the depth stake and the handle pressure required.
organic matter will substantially increase the fertility of your garden. For proper decaying action, fertilizer should be applied and worked in with the mulch materials. Breaking up leaves and straw and mixing it with several inches of soil causes the soil to hold moisture longer and allows proper aeration of the plant root system. This also retards the growth of weeds.
• Maintain engine oil as instructed in the separate engine manual packed with your unit. Read and follow instructions carefully. Remove the hex stop nut and flat washer from the side of the belt cover. Remove belt cover. Lock Nut & Flat Washer Hex Washer Screw Service air cleaner every ten hours under normal conditions. Clean every hour under extremely dusty conditions. Poor engine performance and flooding usually indicates that the air cleaner should be serviced.

Make certain the forward drive belt is assembled with the wide side of the belt away from the transmission and engine pulleys. If the tiller will not be used for a period longer than 30 days, the following steps should be taken to prepare the tiller for storage.
