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
handlebar touches the ground and the unit is in a horizontal
position.
NOTE: It may be necessary to wash dirt off the tines and tine shafts
before removing the tines.
Removing the Old Tines
1. Remove the cotter pin from the end of each tine shaft (Fig. 9).
Slide the tines off of the tine shafts. (Fig. 8).
Installing the New Tines
1. Clean and oil the tine shafts.
2. Slide the new tines onto the tine shafts. The hubs must face
toward each other (Fig. 8). Make sure the rotation arrows face
the gearbox on the left tine shaft and away from the gearbox on
the right tine shaft (Fig. 9).
3. Insert a cotter pin through the hole at the end of each tine shaft
(Fig. 9). Make sure the cotter pins are securely connected.
