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:
o Push the cable through the spring (See Fig. 22) to
expose the threaded portion of the cable.
o Hold the square end of the threaded portion with
pliers and adjust the locknut in or out until the excess
slack is removed..
o Pul! 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.

the belts due to wear or stretch, proceed as follows:
