OPERATION KNOW YOUR SNOW THROWER Read this owner's manual and safety rules before operating your snow thrower. Compare the illustration below with your snow thrower to familiarize yourself with the various controls and their locations. LIFT RELEASE TRIGGER LIFT HANDLE CHUTE TILT HANDLE CRANK ROD UPPER CHUTE LOWER CHUTE SKID SHOE SCRAPER PLATE SPIRAL AUGERS, R.H. & L.H. CHUTE TILT HANDLE Pivots the Upper Chute up or down to control the angle and distance of discharge.
• In extremely deep snow, raise the snow thrower from the ground to remove the top layer and drive forward only until the tractors front tires reach the uncleared bottom layer of snow. Depress the tractor's clutch-brake pedal and allow the spiral auger to clear the snow. Reverse the tractor and lower the snow thrower to the ground. Drive the tractor forward until the snow again becomes too deep. Repeating this process into and out of drifts will eventually clear even the deepest of snow piles.
SERVICE AND ADJUSTMENTS LIFT RELEASE CABLE ADJUSTMENT CAUTION: Before servicing or adjusting • If the lift rod does not lock the snow thrower securely in the transport position, loosen the upper hex nut on the lift bracket a few turns and tighten the lower hex nut. Refer to figure 24 on page 13. • If the lift rod fails to unlock completely to lower the snow thrower, loosen the lower hex nut on the lift bracket a few turns and tighten the upper hex nut. Refer to figure 24 on page 13.
STORAGE ADDITIONAL PARTS TO REMOVE AT END OF SEASON STORAGE RECOMMENDATIONS • Lower the snow thrower to the ground. • Remove the snow thrower from the tractor. • Clean the snow thrower thoroughly. Wash off any salt deposit which may have dried on the thrower and housing. • Any bare metal that has become exposed should be painted or coated with a light oil to prevent rust. • Store in a dry place. • Remove the clutch/idler assembly.
