SERVICE AND

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 between the center and top of the hole in the clutch lever and there is no droop in the _,abie (See FIG. 3).

If adjustment is necessary:

•Remove gas from gas tank, Stand blower on end.

•Disconnect the "Z" Fitting from drive lever.

•Pull spring cover up to expose spring. Push the cable through the spring (See FIG. 4) to expose the threaded

portion of the cable.

•Hold the square end ofthe threaded portion with pliers and adjust the Iocknut in until the excess slack is removed (See FIG. 4 inset)

•Pullthe cable back throughthe spring andconnect 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.
