REPLACING THE TINES
WARNING:

evenly through normal use. Work on one side at a time.
Preparing the Unit for Tine Removal
1. Stop the engine and allow it to cool. Grasp the spark plug wire
firmly and pull the cap from the spark plug.
2. Set the unit on a flat, level surface. Tip the unit back so that the
handles touch the ground and the unit is in a horizontal position.
NOTE: It may be necessary to wash dirt off the tines and tine shaft
before removing the tines.
Removing the Old Tines
1. Remove the cotter pin from the clevis pin (Fig. 11). Remove the
clevis pin from the double tine and tine shaft.
2. Slide the tines off of the tine shaft.
3. Repeat this process for the other side.
