•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 readjusting the auger control cable.

•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 6.

•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 (Refer to Figure 4). If the discharge chute becomes clogged during operation, proceed as follows to safely clean the chute and chute opening:

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

2.Stop the engine by removing the ignition key.

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

4.Use the shovel-shaped end of the clean-out tool to remove any snow and ice in the discharge chute.

WARNING: Never use your hand to clear a clogged discharge chute. Shut off engine and remain behind handles until all moving parts have stopped before unclogging.

5.Refasten the clean-out tool to the mounting clip on the rear of the auger housing, re-start the engine.

6.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 or ice from the discharge chute before continuing to clear snow.

Operating Tips

NOTE: Allow the engine to warm up for a few minutes as the engine will not develop full power until it reaches operating temperature.

WARNING: The muffler, engine and their surrounding areas become hot and can cause a burn. Do not touch.

•Discharge snow downwind whenever possible. Slightly overlap each previous path.

•Set the skid shoes 1/4" below the scraper bar for normal usage. The skid shoes may be adjusted upward for hard-packed snow. Adjust downward when using on gravel or crushed rock.

•Avoid possible starter freeze-up. Clean the snow thrower thoroughly after each use.
