18Section 5: Maintenance

WARNING

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, remove ignition key on electric start models, disconnect spark plug wire and move wire away from spark plug.

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

wheels roll freely when the Wheel Gear Lever is in ENGAGE, the wheel gear cable needs to be adjusted as described below.

1.With engine shut off and spark plug wire disconnected, put Wheel Gear Lever in ENGAGE.

2.Loosen top adjustment nut (A, Figure 5-4) on wheel gear cable bracket located on left side rear of transmission.

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

4.Move Wheel Gear Lever into ENGAGE and DISENGAGE several times to check adjustment. The wheels should not roll when lever is in ENGAGE, but should roll when lever is in DISENGAGE. Readjust cable as required.

OFF SEASON STORAGE

To prepare tiller for extended storage:

1.Clean tiller and engine.

2.Do routine tiller lubrication (see Tiller Lubrication) and check for loose parts and hardware (see Check Hardware).

3.Protect engine by performing the rec- ommended engine storage instructions in Engine Owner’s Manual. NOTE: Be sure to protect fuel lines, carburetor and fuel tank from gum deposits by removing fuel or by treating fuel with fuel stabilizer (follow engine manufacturer’s recommendations).

4.Store unit in a clean, dry area.

5.Never store tiller with fuel in fuel tank in an enclosed area where gas fumes could reach an open flame or spark, or where ignition sources are present (space heaters, hot water heaters, furnaces, etc.).

BOLO TINES

Tines will wear with use and should be inspected at the beginning of each tilling season and after every 30 operating hours. Tines can be replaced individually or as a complete set. Never inspect or service tines unless engine is stopped, spark plug wire is disconnected, and ignition key is removed on electric start models.

A. Tine Inspection:

With use, tines will become shorter, nar- rower and pointed (Figure 5-5). Badly worn tines result in loss of tilling depth and reduced effectiveness when chopping up and turning under organic matter. Use Figure 5-5 as a guide to when to replace tines.

B. Removing a Single Tine:

1.With engine shut off and spark plug wire disconnected, remove two screws and nuts that attach a single tine to a tine holder (Figure 5-6). If needed, use pene- trating oil to help free nuts.

2.When installing a single tine, be sure to position it so that its cutting edge enters the soil first as the tiller moves forward.

C. Removing and Installing

Tine Assemblies:

1.With engine shut off and spark plug wire disconnected, remove tine hood by removing two attaching screws at rear of hood and two attaching screws at front of hood.

2.If removing both tine assemblies, mark them “left” and “right” before removal. Remove the screw and locknut that secure the tine assembly to the tine shaft (Photo

5-7). If necessary, use a rubber mallet to tap tine assembly outward off shaft.

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

4.Install each tine assembly so that the cutting edge of tines enter soil first when tiller moves forward. Secure tine assem- bly to tine shaft using screw and locknut previously removed. Tighten securely.

5.Replace tine hood using four screws previously removed. Tighten securely.
