WARNING: 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. Failure to follow these instructions can result in serious personal injury or property damage.
Carburetor / Governor Adjustment
WARNING: Operators shall not tamper with the engine governor settings; the governor controls the maximum safe operating speed to protect the engine and all moving parts from damage caused by overspeed. Authorized service shall be sought if a problem exists.
The carburetor was adjusted at the factory for best operating speed. Refer to the sep- arate Engine Owner’s Manual for any ad- justment information or see your authorized engine service dealer.
The governor controls the maximum safe operating speed and protects the engine and all moving parts from damage caused by overspeeding. Do not tamper with the engine governor settings. Seek authorized service if a problem exists.
Throttle Control Adjustment
If the engine does not respond to various throttle lever settings, refer to the separate Engine Owner’s Manual for service infor- mation or contact your local authorized en- gine service dealer.
Wheel Gear Cable Adjustment
When the Wheel Gear Lever 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 gear cable needs to be adjusted as described below.
1.With the engine shut off and the spark plug wire disconnected, put the Wheel Gear Lever in ENGAGE.
2.Loosen the top adjustment nut
the wheel gear cable bracket located on the left side rear of the transmission.
3.Push wheel gear cable (B) down and roll tiller slightly forward or backward until ec- centric lever (C) engages (locks) wheels.

Hold cable in that position and tighten top
(A) and bottom (D) adjustment nuts.
4.Move Wheel Gear Lever to ENGAGE and DISENGAGE several times to check adjust- ment. 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’t be used for extended periods, prepare it for storage as follows:
1.Clean the tiller and engine.
2.Do routine tiller lubrication (see Tiller Lubrication) and check for loose parts and hardware (see Check Hardware).
3.Protect the engine by performing the engine storage instructions in the separate Engine Owner’s Manual.
NOTE: Be sure to protect the fuel lines, car- buretor and fuel tank from gum deposits by removing fuel or by treating fuel with a fuel stabilizer (follow engine manufactur- er’s recommendations).
4.Store unit in a clean, dry area.
5.Never store the tiller with fuel in the 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.).
Tines
The 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 the tines unless the engine is stopped and the spark plug wire is disconnected.
NOTE: The tiller hood must be removed to take off either a single tine holder or individual tines. The hood is secured to the transmission housing with two rear bolts and two front bolts.
Tine Inspection
With use, the tines (Figure
Figure 5-6: Four tine gangs: two per side.
Removing and Installing
1.Use a 9/16" socket, 6" extension, a ratchet, and a 9/16" box wrench to loosen the nut (A, Figure
2.Use a rubber mallet to tap the tine hold- er loose.
3.Slide the tine assembly off the tine shaft.
4.Repeat Steps
5.Installing the tine assembly is simply the reverse of its removal. Be sure the cut- ting edges face so they will enter the soil first when the tiller is moving forward– this means the cutting edges face toward the operator position.
First be sure to remove any rust, uneven spots or burrs from the tine shaft, using fine sandpaper. Then grease the tine shaft
