[

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. J

Remove the key from the keyswitch on units so equipped. J

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

WHEELGEARCABLEADJUSTMENT

When the Wheel GearLever is in DISEN- GAGE,the wheels will roll freely (free-

wheel). The wheels should not roll freely when the lever is in ENGAGE.If the

wheels roll freely when the Wheel Gear Lever is in ENGAGE,the wheel gearcable needsto be adjustedas described below.

1. With the engine shut off and the spark

plug wire disconnected, put the Wheel GearLever in ENGAGE.

2.Loosen the top adjustment nut (A,

Figure 5-4) on the wheel gear cable bracket that is located on the left side rear

of the transmission.

3.Push the wheel gear cable (B) down and roll the tiller slightly forward or back- ward until the eccentric lever (C) engages (locks) the wheels. Hold the cable in that position and tighten the top (A) and bottom (D) adjustment nuts.

4.Move the Wheel Gear Leverto

ENGAGEand DISENGAGEseveraltimes to check the adjustment. The wheels should not roll when the lever is in

ENGAGE,but they should roll when the lever is in DISENGAGE.Readjust the cable as required.

OFF SEASON STORAGE

When the tiller won'tbe used for extendedperiods, prepare it for storage as follows:

1.Cleanthe tiller and engine.

2.Do routine tiller lubrication and check for loose parts and hardware.

3.Protect the engineand perform recom- mendedengine maintenanceby following the engine storage instructions found in the separateEngineOwner'sManual. NOTE:Besure to protect the fuel lines, carburetor and fuel tank from gum deposits by removing fuel or by treating fuel with a fuel stabilizer (follow engine manufacturer'srecommendations).

4.On electric start units, follow "Battery Storage" instructions in this Section.

5.Store unit in a clean, dry area.

6.Neverstore the tiller with fuel in the fuel tank in an enclosed areawhere gas fumes could reachan openflame or spark, or where ignition sources are present (spaceheaters, hot water heaters, furnaces, etc.).

BOLOTINES

The tines will wear with useand should be inspectedat the beginning of each tilling seasonand after every 30 operating hours. Tines can be replaced individually or as a complete set. Neverinspect or servicethe tines unless the engineis stopped, the spark plug wire is discon-

nected,and the ignition keyis removed on electric start models.

A.Tine Inspection:

With use, the tines will become shorter, narrower and pointed (Figure 5-5). Badly worn tines will result in a loss of tilling depth and reduced effectivenesswhen chopping up and turning under organic matter. UseFigure 5-5 as a guide to when the tines should be replaced.

B. Removinga Single Tine:

1. Removethe two screws and nuts that attach a single tine to the tine holder (Figure 5-6). If needed,use penetrating oil to helpfree the nuts.

2.When installing a single tine, be sure

to position it so that its cutting edge will enter the soil first as the tiller moves

forward.

C. Removinga Tine Assembly:

1.If removing both tine assemblies, mark them "left" and "right" before removal.

Doing so will help ensure that the assem- blies are reinstalled on the correct sides

of the tiller.

2.Removethe screw and Iocknut that

secure the tine assembly to the tine shaft (Photo 5-7). Pull the tine assembly off the shaft (if necessary,use a rubber mallet to tap the tine assembly outward).

3.Before reinstalling the tine assembly, inspect the tine shaft for rust, rough spots or burrs and file or sand as needed. Apply a thin coat of greaseto the shaft.

4.Install each tine assembly so that the cutting edge of the tines will enter the soil first when the tiller moves forward.

Secure the tine assembly to the tine shaft using the screw and Iocknut previously removed. Tighten securely.
