Auger Control
The auger control is located on the left handle. Squeeze the
control grip against the handle to engage the augers and start
snow throwing action. Release to stop.
Drive Control / Auger Clutch Lock
The drive control is located on the right handle. Squeeze the
control grip against the handle to engage the wheel drive.
Release to stop.
The drive control also locks the auger control so that you can
operate the chute directional control without interrupting
the snow throwing process. If the auger control is engaged
simultaneously with the drive control, the operator can release
the auger control (on the left handle) and the augers will remain
engaged. Release both controls to stop the augers and wheel
drive.
Note: Always release the drive control before changing speeds.
Failure to do so will result in increased wear on your machine's
drive system.
