safety instructions to prevent serious personal injury.
REPLACING THE TINES
WARNING:
To prevent serious personal injury, always
wear heavy gloves when handling the tines.
All tines should be replaced at the same time, as they will wear
evenly through normal use.
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 click pin from the end of each tine shaft (Fig. 10).
Slide the tines off of the tine shafts. (Fig. 9).
Installing the New Tines
1. Clean and oil the tine shafts.
2. Slide two new tines onto one of the tine shafts. The hubs must
face toward each other (Fig. 9).
NOTE: Each tine has a convex side. Make sure that the convex
sides are facing as shown (Fig. 10).
3. Insert a click pin through the hole at the end of the tine shaft
(Fig. 10). Push the click pin ring toward the tines until it clicks
into place.
4. Repeat steps 2 - 3 for the opposite side.
5. Reconnect the spark plug wire.
