Safety Rules WARNING WARNING This unit is a “two-stage” snowthrower. To avoid serious injury, do not put your hands into the auger housing or discharge chute. If auger stalls or chute becomes plugged, use the following procedure to remove objects or clear the chute: The first stage is the auger, which feeds the snow back into the impeller housing. The second stage is the impeller, which throws the snow out the discharge chute.
Safety Rules OPERATION MAINTENANCE & STORAGE • Keep hands and feet away from rotating parts. Keep clear of discharge opening at all times. • Keep all nuts, bolts and screws tight to ensure that the equipment is in safe operating condition. • Always clear snow up and down the face of slopes, never across the face. Use extreme caution when changing direction on slopes. Do not attempt to clear slopes over 17.7% (10o).
Safety Signs & Decals SAFETY DECALS Safety warning decals are placed at strategic locations on the snowthrower as a constant reminder to the operator of the most important safety precautions. All warning, caution and instructional messages on your snowthrower should be carefully read and obeyed. If any of these decals are lost or damaged, replace them at once. They can be purchased from your local dealer. WARNING TO AVOID SERIOUS INJURY • Read Owner’s Manual before operating unit.
Control Reference Chart SNOWTHROWER CONTROLS A Speed Selector Selects Forward Speeds 1 - 5, Reverse Speeds 1 - 2 B Drive Control Engages drive to wheels as it is depressed; disengages when released. D A C Auger Control Engages auger/impeller as it is depressed; disengages when released. D Chute Direction Control Rotates discharge chute to desired direction E Chute Deflector Controls vertical angle snow is thrown.
Controls STARTING CONTROLS B Electric Start Units Only * A A. Electric Start Button - The Electric Start Button (A, Figure 3) activates an electric starter mounted to the engine, eliminating the need to pull the starter handle. The Electric Start Button operates on 120 Volts AC, which is provided by connection to the extension cord provided with units equipped with this feature. Connect this extension cord ONLY to a properly grounded 3 prong electrical outlet. C Manual Start B.
Controls GROUND SPEED CONTROLS A FRONT A. Speed Selector - This lever (A, Figures 4 & 5) is used to set the ground speed of the snowthrower. The snowthrower has five forward speeds, 1–5, and two reverse speeds, 1–2. No neutral position or gate is required, since the traction drive design automatically provides "neutral" (no forward or reverse movement), whenever the Drive Control is released. B.
Operation GENERAL OPERATION CHECKS BEFORE EACH START-UP WARNING 1. Make sure all safety guards are in place and all nuts, bolts and clips are secure. To avoid serious injury, do not put your hands into the auger housing or discharge chute. If auger stalls or chute becomes plugged, use the following procedure to remove objects or clear the chute: 2. Check the engine oil level. See your engine Owner’s Manual for procedure and specifications. 1. 2. 3. 4. 5. 6. 3.
Operation STARTING THE ENGINE B 1. Turn the fuel valve (B, Figure 6) to the ON position. * A 2. Insert the Engine Key (F, Figure 6) into the Engine Key slot and push fully in to the RUN position. C 3. Move the Throttle Lever (E, Figure 6) fully up to the FAST position. 4. Turn the Choke Knob (G, Figure 6) fully clockwise if engine is cold. (Do not choke a warm engine.) 5. Push the Primer Button (D, Figure 6) two times if engine is cold. (Do not prime a warm engine.) 6.
Operation ENGINE SPEED Throttle Lever For overall best performance, run the snowthrower at full engine operating speed. Use the engine Throttle Lever (See Figure 8) to set the engine speed. Slide the Throttle Lever UP to increase engine speed, and DOWN to reduce speed. GROUND SPEED SELECTOR Use the Speed Selector (A, Figure 7) to control the drive speed of the snowthrower. There are five forward speeds and two reverse speeds. Use the lower speeds to blow deep or wet snow.
Operation FREE-WHEELING AND TRACTION DRIVE LOCK For easy turning when pushing the snowthrower, you can disengage the traction drive at one or both wheels by using the Traction Lock Pins (See Figures 11 & 12.) 1. Turn the unit off, remove the Engine Key, and disconnect the spark plug wire. Klik-Pin In OUTER Hole 2. To DISENGAGE the traction drive lock, insert the Traction Lock Pin through the outer hole in the axle. (See Figure 8). 3.
Regular Maintenance NORMAL CARE CARE REQUIRED SEE PAGE FREQUENCY Check auger gear case lubrication.* Page 12 25 Hours Simplicity Winter Weight Worm Gear Oil Lubricate snowthrower. Page 13 10 Hours 10W Oil and Grease Check tire pressure. Page 22 Monthly N/A Change engine oil.**✛ - 50 Hours✛ See Engine Manual Clean or replace spark plug.
Regular Maintenance LUBRICATION IMPORTANT NOTE It is very important that grease fittings on the auger shaft are lubricated regularly. If auger rusts to shaft, damage to worm gear may occur if shear pins do not break. To prevent wheels rusting to axles, it is also necessary to remove the wheels and grease the axles regularly. There are two grease fittings on the auger shaft (Figure 15). Wipe the fittings clean and apply grease, using a grease gun. Also apply grease on other points indicated.
Service TROUBLESHOOTING This section provides troubleshooting and service instructions. Locate the problem and check the possible cause/remedy in the order listed. WARNING Before performing any adjustment or service to snowthrower, stop the engine and wait for moving parts to stop. Remove the key. To prevent accidental starting, disconnect the spark plug wire and fasten away from the plug. Also, refer to the engine manufacturer’s Owner’s Manual for additional information.
Service PROBLEM POSSIBLE CAUSE REMEDY 1. Chute deflector too low. 1. Adjust deflector as necessary. 2. Engine speed too slow. 2. Set speed to full throttle. 3. Ground speed too fast. 4. Snowthrower discharge chute clogged. 3. Use slower Speed Selector setting. 4. STOP engine and REMOVE the key. DISCONNECT the spark plug wire. Clear auger using a narrow board. See warning in SAFETY RULES. 5. Auger belt loose or worn. 5. Check Auger Drive Belt Adjustment Scraper bar does not clean hard surface. 1.
Service SPEED SELECTOR PIVOT ADJUSTMENT Speed Selector The Speed Selector is factory set for optimal performance at each forward and reverse speed setting. However, if speed position 1 is too slow, the speed can be increased by changing the pivot position one turn. Do not turn pivot more than one turn - increasing forward speed using this method reduces reverse speed by a like amount, and inadequate reverse speeds will result. Hitch Clip Pin Adjust as follows: 1.
Service AUGER DRIVE CLUTCH ROD ADJUSTMENT The auger drive clutch rod should be adjusted so that there is no slack in the rod when moved slightly from side to side. To adjust tension on the rod: Auger Drive Clutch Rod 1. Loosen adjustment hex nuts (Figure 19). 2. Tighten top hex nut while holding rod. Tighten just until slack in rod is removed. Be careful not to move idler rod lever when adjusting clutch rod tension.
Service DRIVE BELT ADJUSTMENT (Continued) If the auger drive slips (auger slows or doesn't rotate normally while blowing snow), or stays engaged when the control is disengaged — and the auger clutch rod has been properly adjusted — the auger drive belt may be out of adjustment. Auger Control Belt Cover WARNING Auger must NOT rotate unless the Auger Control lever has been depressed. Proper Auger Drive Belt adjustments stop the auger within 5 seconds after the Auger Control is disengaged. Figure 21.
Service DRIVE BELT ADJUSTMENT (Continued) Adjusting Auger Belt Guide WARNING 1. With the Auger Control still fully depressed, adjust the Auger Belt Guide so that there is a 1/64” gap (1/32” Maximum) between the end of the guide and the belt (Figure 22c), making certain the guide is NOT putting pressure on the belt. 2. Making certain the Auger Belt Guide does NOT move while doing so, tighten the Auger Belt Guide Screw (Figure 22c) to secure the guide. 3.
Service DRIVE BELT REPLACEMENT (Cont.) WARNING Auger Drive Belt Replacement Do not go near the discharge chute or auger when the engine is running. Do not run the engine with any cover or guard removed. 1. Remove gas from fuel tank and run engine until it stops running from lack of fuel. 2.
