2.Flip open the ring (A, Figure 12) on the left side ring lock pin and remove the ring lock pin.
IMPORTANT: The ring lock pin (A, Figure
12)is under spring tension – use care when removing or replacing the ring lock pin.

Arranging Tines for Stony Soil
1.Prop the machine forward so it rests on the front of the tubular carrying handle. The work surface should be flat and firm.
2.Remove the ring lock pin (A, Figure 12) from both sides of the unit. Remove both outer tine sections. Be sure to mark each section as a left or right side tine and whether it is an inner or outer section.
3.Remove the inner tine sections and
swap their positions (the inner
4.Reinstall the two outer tine sections onto the sides from which they were removed (Figure 14).
5.Insert the ring lock pins through the rounded side of the tine shafts and snap the rings down over the shafts (see DETAIL - Ring Lock Pin, Figure 10, in Sec- tion 4).
