Poulan 193733 manual VARI-SPEED Drive Control, VARI-SPEED Thumbscrew Adjustment

“VARI-SPEED” DRIVE CONTROL

•Self-propelling is controlled by hold- ing the operator presence control bar down to the handle and pulling the drive control bar up to the handle. The closer to the handle the bar is pulled, the faster the unit will travel.

•Forward motion will stop when either the operator presence control bar or drive control bar are released. To stop forward motion without stopping engine, release the drive control bar only. Hold operator presence control bar down against handle to continue mowing without self- propelling.

NOTE: If after releasing the drive control the mower will not roll backwards, push the mower forward slightly to disengage drive wheels.

FRONT WHEEL DRIVE MODELS ONLY:

•To keep drive control engaged when turning corners, push down on the handle to lift the front wheels off the ground while turning lawn mower.

the same), your drive belt is worn and should be replaced.

NOTE: If mower begins to "creep" forward, the drive cable is too tight. Rotate thumb- screw clockwise to loosen drive cable.
