control. The auger should come to a complete stop in
5 seconds. If auger does not come to a complete stop
in the required time, check and adjust belt tension.

upper end of cable. Hold threaded end of cable and
then turn cable clockwise or counter clockwise until
correct extension is achieved. Retighten jam nut.
IMPORTANT: DO NOT over tighten the control cables. The
cables must have slack for the auger/impeller brake to
function properly and for the wheel drive to de-clutch
properly. If the auger control cannot be properly adjusted,
belt adjustment and/or replacement will be required. Refer
to Section "Auger Belt Idler Pulley Adjustment". If the wheel
drive control cannot be properly adjusted, Refer to Section
"Rubber Drive Disc Replacement".

must first be loosened as described in the following
step. Cable adjustment must be checked after
completing the idler pulley adjustment.
1. Loosen jam nut at the end of cable. Hold threaded
end of cable and then turn metal housing of cable
counter clockwise until threaded portion of cable is
extracted from metal housing. Reinstall 1/2" of the
