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 USE THROTTLE CONTROL (See Fig. 13) The throttle control is located on the engine. Always operate the snow thrower with the engine at full throttle.
OPERATION TO MOVE FORWARD AND BACKWARD (See Fig. 17) 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 POWER STEERING OPERATION (See Fig. 18) Steering triggers are used to assist in steering your snow thrower. The triggers are located on the underside of each handle. When a trigger is squeezed, it disengages the drive wheel on that side of snow thrower and allows it to turn in that direction. • To turn left – squeeze left side trigger. • To turn right – squeeze right side trigger. LH TURN TRIGGER SCRAPER BAR (See Fig. 19) After considerable use it may become worn.

Push the primer three (3) times. NOTE: Over priming may cause flooding, preventing the engine from starting.
OPERATION IF RECOIL STARTER HAS FROZEN If the recoil starter has frozen and will not turn the engine, proceed as follows: 1. Grasp the recoil starter handle and slowly pull as much rope out of the starter as possible. 2. Release the recoil starter handle and let it snap back against the starter. If the engine still fails to start, repeat the above steps or use the electric starter. SNOW THROWING TIPS • • • • • • • • • • • Always operate the snow thrower with the engine at full throttle.
MAINTENANCE GENERAL RECOMMENDATIONS LUBRICATION CHART ➀ SAE 30 Motor Oil ➁ See “ENGINE” in 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.
MAINTENANCE BELTS Check 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 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 IMPELLER SHEAR BOLTS The impeller is secured to the impeller shaft with two (2) capscrew/shear bolts and hex nuts. Should a foreign object or ice become lodged in the impeller, the capscrews are designed to break, preventing damage to any other components. If impeller does not turn when auger control lever is engaged, check to see if the capscrews have sheared. To replace the capscrew/shear bolts: 1. Disengage all controls and move throttle control to STOP position.
SERVICE AND ADJUSTMENTS TO REPLACE BELTS (See Fig. 24) 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 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 ADJUST CABLE TENSION (See Fig. 26) Adjust cable tension by turning the adjuster turn buckle, located on the right hand cable. Grasp the long section tightly and turn the short section to lengthen the adjuster. Adjust until cable is snug. TO REMOVE WHEELS (See Fig. 25) • Remove the wheel pin and retainer pin and remove wheel from axle. NOTE: To seal punctures or prevent flat tires due to slow leaks, tire sealant may be purchased from your local parts dealer.
STORAGE ENGINE OIL Drain oil (with engine warm) and replace with clean engine oil. (See “ENGINE” in the Maintenance section of this manual). 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. WARNING: Never store the snow thrower with gasoline in the tank inside a building where fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer or gas appliance.
