TO ADJUST THE CLUTCH CONTROL
CABLES
Periodic adjustment of the cables may be required due to normal stretch and wear on the belts,. To check for correct adjustment, the control lever must be in the full forward position, resting on the plastic bumper.. The control cables are correctly adjusted when the center of the "Z" Fitting is in the center of the hole and there is no slack in the cable (See Fig. 21)
If adjustment is necessary:
oPush the cable through the spring (See Fig. 22) to expose the threaded portion of the cable.
oHold the square end of the threaded portion with
pliers and adjust the locknut in or out until the excess slack is removed..
oPul! the cable back through the spring and connect the cable,
®Do the same for the other lever cable°
NOTE: Whenever the traction drive or auger belts are adjusted or replaced, the cables will need to be adjusted.
