Tine removal and installation
To remove tines
1. Remove the cotter pins from each end of the tine shaft.
2. Slide the four tines off the shaft.
To install tines
1. First slide the inside tines onto each end of the tine shaft. One inside tine is stamped with a "B" and the other is stamped with a "C".
2. Slide the outside tine "A" and tine "D" onto each end of the shaft next. The tines should be installed in the correct order so that they are positioned left to
right A, B, C, D, as viewed from the user's position on the mini cultivator. Make sure that the hub collars on both the right and left pairs of tines face each other
so that there is adequate spacing between the tine blades. (See Figure 3.)
3. Insert the cotter pins into the holes at each end of the tine shaft to lock the tines into place.

Adjusting the wheels
The wheels on the cultivator can be adjusted to one of three positions. The lowest wheel position is used for transporting the cultivator across a smooth
level surface while the engine is not running. The two higher positions are used when cultivating in soil and help stabilize the unit when cultivating at
different depths. (See Figure 6.)
To adjust the wheels up or down, see Figures 4 and 5.
1. Pull the locking metal sleeve against the spring until it releases from one of the three holes in the vertical guide.
2. Slide the wheel set up or down to the desired position, and release the locking metal sleeve until it locks into one of the three holes in the vertical guide.
