Section 5: Maintenance

WARNING

Before inspecting, cleaning or servicing the machine, shut off engine, wait for moving parts to stop, dis- connect spark plug wire and move wire away from spark plug.

Failure to follow these instructions can result in serious personal injury or property damage.

REPLACING WORN TINE SECTIONS

The tines are excessively worn if tilling takes much longer than before and soil is not being mixed thoroughly enough.

1.Prop the machine forward so it rests on the front of the tubular carrying handle. The work surface should be flat and firm.

2.Remove the ring lock pin (A, Figure 12) from both sides of the unit. Remove the old tine sections and replace them with new tine sections. Refer to Figure 12 and the tine position shown in the Parts List for tine positioning details. Insert the ring lock pins through the rounded side of the tine shafts and snap the ring over the shaft (see DETAIL - Ring Lock Pin, Figure 10, in Section 4).

STORAGE

WARNING

Never store your equipment when there is fuel in the fuel tank.

Never place your equipment near any source of sparks or open flame (such as from a hot water heater, a space heater or clothes dryer).

Failure to comply can result in serious personal injury or property damage.

IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor, fuel filter, fuel hose, or tank during storage. Also, experience indicates that alcohol- blended fuels (called gasohol or using ethanol or methanol) 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.

OFF-SEASON STORAGE PROCEDURE

Protect the engine and perform recom- mended engine maintenance by fol- lowing the engine storage instructions found in the separate Engine Owner’s Manual.

NOTE: Be sure to protect the fuel lines, carburetor and fuel tank from gum de- posits by removing the fuel or by treating the fuel with a stabilizer. See Engine Owner’s Manual for more infor- mation.

Remove tines. Clean all soil and debris from dust covers and tine shaft. Lubri- cate tine shaft with light oil. Replace tines.

Cover engine and store equipment in a dry, sheltered location.
