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, re check 

“OFF” position adjustment to insure tines do not rotate when 
control is “OFF” (up).
