TINE REMOVAL AND REPLACEMENT
WARNING:
To prevent serious personal injury, always

position.
All 4 tines should be replaced at the same time because they will

1. Stop the engine and allow it to cool. Grasp the spark plug wire
firmly and pull the cap from the spark plug.
2. Lay the cultivator back on a flat level surface with the handles
touching the ground so that the cultivator is in a horizontal position.
NOTE: It may be necessary to wash any dirt off the tines and shaft
for easier tine removal.
3. Remove the click pins from each end of the tine shaft (Fig. 8).
Slide the tines off of the shaft.
4. Clean and oil the shaft.
5. Slide on the new tines with the hubs facing in towards each
other (Fig. 8).
NOTE: Each tine has a convex side. Make sure that all of the
convex sides are facing as shown in Figure 8.
