Check the adjustment of the auger control as follows:

•When the auger control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight.

•In a well-ventilated area, start the snow thrower engine as instructed earlier in this section under the heading Starting Engine. Make sure the throttle is set in the FAST position.

•While standing in the operator’s position (behind the snow thrower), engage the auger.

•Allow the auger to remain engaged for approximately ten (10) seconds before releasing the auger control. Repeat this several times.

•With the engine running in the FAST position and the auger control lever in the disengaged “up” position, walk to the front of the machine.

•Confirm that the auger has completely stopped rotating and shows NO signs of motion.

IMPORTANT: If the auger shows ANY signs of rotating, immediately return to the operator’s position and shut off the engine. Wait for ALL moving parts to stop before re-adjusting the auger control.

•To readjust the control cable, loosen the hex jam nut on the auger control cable “Z” fitting.

•Rotate the coupling end of the cable counterclockwise to provide more slack.

•Retighten the hex jam nut. See Figure 17.

•Repeat Auger Control Test to verify proper adjustment has been achieved.

Chute Clean-Out Tool

The chute clean-out tool is conveniently fastened to the rear of the auger housing with a mounting clip. Should snow and ice lodge itself in the discharge chute during operation, proceed as follows to safely clean the chute and chute opening:

•Release both the Auger Control Lever and the Traction/Auger Control Lock Lever.

•Stop the engine by removing the ignition key.

•Remove the clean-out tool from the clip which secures it to the rear of the auger housing.

•Use the shovel-shaped end of the clean-out tool to dislodge and scoop any snow and ice which has formed in and near the discharge chute.

WARNING: Never use your hands to clean snow and ice from the discharge chute or auger housing

•Refasten the clean-out tool to the mounting clip on the rear of the auger housing, reinsert the ignition key and start the snow thrower’s engine.

•While standing in the operator’s position (behind the snow thrower), engage the auger clutch lever for a few seconds to clear any remaining snow and ice from the discharge chute.

Drift Cutters (If Equipped)

Drift cutters should be used when operating the snow thrower in heavy drift conditions.

On models so equipped, drift cutters are assembled to the auger housing inverted. Remove the carriage bolts by unthreading the hex nuts which secure them, and reinstall the drift cutters in their proper position before operating the snow thrower. See Figure 18.
