Assembly

WARNING

Read, understand, and follow all instructions and warnings posted on the machine and in this manual before operating.

STEP 6: CHECK TRANSMISSION OIL LEVEL

The transmission was filled with gear oil at the factory. However, you should check the gear oil level at this time 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 transmission components.

1.With the tiller on level ground, pull the Depth Regula- tor Lever (FF, Fig. 2-10) back and then all the way up until the lowest notch in the lever is engaged.

2.Remove the oil fill plug (GG, Fig. 2-11) from the transmission housing cover and locate the main drive shaft situated inside the housing.

3.The gear oil level is correct if the gear oil is approxi- mately halfway up the side of the main drive shaft.

4.If the oil level is low, add gear oil by referring to A. To Check the Transmission Gear Oil Level in Section 5.

STEP 7: ADD MOTOR OIL

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 separate Engine Owner’s Manual for engine oil specifications and capacities.

2.With the tiller on level ground, move the Depth Regulator Lever (FF, Fig. 2-10) up or down 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, which allows the tiller to be moved without the tines touching the ground.

STEP 8: CHECK HARDWARE

Check all nuts and screws for tightness.

STEP 9: CHECK AIR PRESSURE IN TIRES (units with pneumatic tires)

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