Section 2: Assembly

4.Insert the cable up through the slot in the cable bracket and position the threaded assembly as shown in Fig. 2-8. Make sure that the flat side of the threaded assembly is aligned with the flat side of the mounting hole. Slide the large hex nut (DD) up the cable and tighten it securely.

5.Use a cable tie (EE, Fig. 2-9) to fasten the reverse clutch cable to the left side handlebar.

6.Test the function of the reverse clutch cable by pulling the knob out and releasing it. The knob should return to its neutral position (resting against bracket) when it is released. If it doesn’t, contact your local dealer or the factory for technical assistance.

STEP 6: Check Level of

Transmission Gear Oil

The transmission was filled with gear oil at the factory. However, you should check the gear oil level to make certain it is correct.

IMPORTANT: Do not operate the tiller if the gear oil level is low. Doing so will result in severe damage to the transmis- sion components.

1.Put the tiller on level ground. Pull the Depth Regulator Lever (FF, Fig. 2-10) back and then adjust it up or down to the notch that makes the tiller level.

2.Remove the oil fill plug (GG, Fig. 2-11) from the transmission housing and look into the oil fill hole. You will see the main drive shaft on one side of the hole.

3.The gear oil level is correct if the gear oil is approximately halfway up the side of the drive shaft.

4.If the gear oil level is low, add gear oil by referring to “A. To Check the Transmis- sion Gear Oil Level” in Section 5.

STEP 7: Add Motor Oil to Engine

The tiller is shipped without oil in the engine.

IMPORTANT: Do not start the engine without first adding motor oil. Severe engine damage will result if the engine is run without oil.

1.Refer to the Engine Owner’s Manual (supplied with tiller) for engine oil specifi- cations and capacities.

2.With the tiller on level ground, pull the Depth Regulator Lever (FF, Fig. 2-10) back and then slide it up or down as necessary until the engine is level.

3.Add motor oil as described in the Engine Owner’s Manual.

4.Move the Depth Regulator Lever all the way down until the highest notch is engaged. This places the tines in the “travel” position.

STEP 8: Check Hardware for Tightness

Check all nuts and screws for tightness.

STEP 9: Check Air Pressure in Tires)

Use a tire pressure gauge to check the air pressure in both tires. Deflate or inflate both tires equally to 15-to-20 PSI (pounds per square inch). Be sure that both tires are inflated equally or the unit will pull to one side.

IMPORTANT: This completes the assembly steps. Before operating your tiller, make sure you read the following Sections in this Manual, as well as the separate Engine Owner’s Manual:

•Section 1: “Safety”

•Section 3: “Features and Controls”

•Section 4: “Operation”
