SERVICE AND ADJUSTMENTS

TINE OPERATION CHECK (See Fig. 19)

WARNING: Disconnect spark plug wire from spark plug to prevent starting while checking tine operation.

For proper tine operation, forward tine control lever must be against control body and all slack removed from inner wire of control cable when control is in the “OFF” (up) position.

If lever and cable are loose, loosen cable clip at lower end of cable. Pull up on cable to remove slack, without extending spring on end of cable, and retighten cable clip.

FINAL CHECK “OFF” POSITION

With tine control “OFF” (up), push down on handle to raise tines off the ground.

Slowly pull recoil starter handle while observing tines. Tines should not rotate.

If tines rotate, inner wire of control cable is too tight which is extending lower spring and engaging tines. Loosen cable clip and push down on cable only enough to relieve spring tension. Tighten cable clip.

Recheck in “OFF” position and adjust if necessary.

FINAL CHECK “ON” POSITION

With tine control “ON” (held down to handle) push down on handle to raise tines off the ground.

Slowly pull recoil starter handle while observing tines. Tines should rotate forward.

If tines do not rotate, inner wire of control cable is too loose. Loosen cable clip and pull cable up to remove slack and retighten clip.

Recheck in “ON” position and adjust if necessary. NOTE: If “ON” position check required adjustment, recheck “OFF” position adjustment to insure tines do not rotate when control is “OFF” (up).
