Auger Control Test

IMPORTANT: Perform the following test before operating your snow thrower for the first time and at the start of each winter season.

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.

WARNING: Do not over-tighten the cable. Over-tightening may prevent the auger from disengaging and compromise the safety of the snow thrower.

•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 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.

•Thread the ferrule without turning

the cable onto the “Z” fitting until there is no slack in the cable. See Figure 8. Do not overtighten the cable. Hold the flats on the ferrule with pliers and tighten the jam nut against the ferrule.

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

•Retighten the hex jam nut. See Figure 8.

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

Clean-Out Tool

The chute clean-out tool is conveniently fastened to the rear of the auger housing with a mounting clip. Never use your hand to clean a clogged chute or chute opening; use this clean-out tool instead.

•Release both the Auger Control and the Drive/ Auger Control Lock.

•Stop the engine by moving the throttle to the stop position.

•Remove the clean-out tool from the mounting clip. See Figure 6.

•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 chute assembly.

WARNING: Never use your hands to clean snow and ice from the chute assembly 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 control for a few seconds to clear any remaining snow and ice from the chute before continuing to clear snow.

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 9.

If your unit is not equipped with drift cutters, contact Customer Support as instructed on page 2 for information regarding price and availability.
