IMPORTANT Safe Operation Practices for Walk-Behind Snow Throwers This snow thrower is capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury. WARNING: Snow throwers have exposed rotating parts, which can cause severe injury from contact, or from material thrown from the discharge chute. Keep the area of operation clear of all persons, small children and pets at all times including startup.
6. When cleaning, repairing or inspecting the snow thrower, stop the engine and make certain the collector/impeller and all moving parts have stopped. Disconnect the spark plug wire and keep the wire away from the plug to prevent someone from accidentally starting the engine. 7. Do not run the engine indoors, except when starting the engine and for transporting the snow thrower in or out of the building. Open the outside doors; exhaust fumes are dangerous. 8.

OPERATION The operation of any snow thrower can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your snow thrower or performing any adjustments or repairs. We recommend standard safety glasses or a wide vision safety mask worn over spectacles. TO CONTROL SNOW DISCHARGE (See Figs.
OPERATION TO MOVE FORWARD AND BACKWARD (See Fig. 15) SELF-PROPELLING, forward and reverse movement of the snow thrower, is controlled by the traction drive control lever located on the left side handle. • Squeeze traction drive control lever to handle to engage the drive system. • Release traction drive control lever to stop the forward or reverse movement of the snow thrower. SPEED and DIRECTION are controlled by the drive speed control lever.
OPERATION • If snow thrower must be operated over gravel surface, use extra caution and be sure skid plates are adjusted to lowest (highest scraper clearance) position. 1. Shut off engine and wait for all moving parts to stop. 2. Adjust skid plates by loosening the hex nuts, then moving skid plate to desired position. Be sure both plates are adjusted evenly. Tighten securely.
OPERATION Allow the engine to warm up for a few minutes. Engine will not develop full power until it has reached normal operating temperature. WARM START - ELECTRIC STARTER Follow the steps above, keeping the choke control in the “OFF” position. COLD START - RECOIL STARTER 1. Insert safety ignition key (packed separately in parts bag) into ignition slot until it clicks. DO NOT turn the key. Keep the extra safety ignition key in a safe place. 2. Place ON / OFF switch in “ON” position. 3.
MAINTENANCE GENERAL RECOMMENDATIONS LUBRICATION CHART The warranty on this snow thrower does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain snow thrower as instructed in this manual. Some adjustments will need to be made periodically to properly maintain your snow thrower. At least once a season, check to see if you should make any of the adjustments described in the Service and Adjustments section of this manual.
MAINTENANCE V-BELTS Check V-belts for deterioration and wear after every 50 hours of operation and replace if necessary. The belts are not adjustable. Replace belts if they begin to slip from wear. (See “TO REMOVE BELT COVER” in the Service and Adjustments section of this manual). The V-belts on your snow thrower are of special construction and should be replaced by original equipment manufacturer (OEM) belts available from your nearest dealer.
SERVICE AND ADJUSTMENTS 1. Disengage all controls and move throttle control to STOP position. Wait for all moving parts to stop. 2. Remove safety ignition key and disconnect spark plug wire from spark plug. Place wire where it cannot come in contact with spark plug. 3. Align holes in impeller hub with holes in impeller shaft and install two (2) new 1/4-20 x 1-5/8" capscrew/shear bolts. Install 1/4-20 locknuts and tighten securely.
SERVICE AND ADJUSTMENTS TO REPLACE BELTS (See Fig. 20) The auger and traction drive belts are not adjustable. If the belts are damaged or begin to slip from wear, they should be replaced. It is recommended that the belt(s) be replaced by a Sears service center/department. NOTE: It is recommended that both the auger and traction drive belt be replaced at the same time.
SERVICE AND ADJUSTMENTS TO REMOVE WHEELS (See Fig. 21) • Remove the klik pin and remove wheel from axle. IMPORTANT: When installing wheel, be sure to use the innermost hole in axle and the wheel hub hole. To disengage drive system from the wheels (for pushing or transporting the snow thrower), remove klik pin from wheel hub and insert pin into the outermost hole in axle only. KLIK PIN ENGINE SPEED Never tamper with the engine governor, which is factory set for proper engine speed.
STORAGE Immediately prepare your snow thrower for storage at the end of the season or if the unit will not be used for 30 days or more. • Empty the fuel tank by starting the engine and letting it run until the fuel lines and carburetor are empty. • Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. • Use fresh fuel next season. NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage.
