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 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.
Controls SNOWTHROWER CONTROLS A B Speed Selector Selects Forward Speeds 1 - 5, Reverse Speeds 1 - 2 Drive Control Engages drive to wheels as it is depressed; disengages when released. 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 A B Electric Start Units Only 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 G All Models B.
Controls GROUND SPEED CONTROLS A C A. Speed Selector - This lever (A, Figures 4 & 5) is used to set the ground speed of the snowthrower. B D 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 A B 1. Turn the fuel valve (B, Figure 6) to the ON position. 2. Insert the Engine Key (F) into the Engine Key slot and push fully in to the RUN position. 3. Move the Throttle Lever (E) fully up to the FAST position. 4. Turn the Choke Knob (G) fully clockwise if engine is cold. (Do not choke a warm engine.) 5. Push the Primer Button (D) two times if engine is cold. (Do not prime a warm engine.) 6.
Operation GROUND SPEED SELECTOR A Use the Speed Selector (A, Figure 8) 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. Use the higher speeds to blow light snow or to drive the snowthrower without blowing snow. To change speeds, first release the traction Drive Control lever (B, Figure 8), then move the Speed Selector to the desired speed setting.
Operation FREE-WHEELING AND TRACTION DRIVE LOCK Klik-Pin In OUTER Hole 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. 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 FREQUENCY LUBRICATION Check auger gear case lubrication.** 25 Hours Simplicity Winter Weight Worm Gear Oil Lubricate snowthrower. 10 Hours 10W Oil and Grease Check tire pressure. Monthly N/A Change engine oil.*✛ 50 Hours✛ See Engine Manual Yearly See Engine Manual 4-6 Hours N/A Clean or replace spark plug.✛ Check drive linkage/belt tension * Change original oil after two hours of operation. ** Check oil level each fall and spring.
Regular Maintenance Figure 14. Checking Tire Pressure Figure 15. Lubricate Points Where Chute Contacts Flange (oil); Lubricate Ring Gear and Pinion Gear While Rotating Spout (grease) CHECKING TIRE PRESSURE The air pressure in each tire should be 20 psi (136 kPa) and should be equal for both tires for best performance. Be sure to keep caps on valves to prevent entry of debris into the valve stem when tires are filled.
Troubleshooting, Adjustments, & 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.
Troubleshooting, Adjustments, & Service PROBLEM Auger rotates, but snow is not thrown far enough 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. 3. Use slower Speed Selector setting. 4. Snowthrower discharge chute clogged. 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.
Troubleshooting, Adjustments, & Service TRACTION DRIVE SYSTEM ADJUSTMENT A Speed Selector Pivot Adjustment The Speed Selector is factory set for optimal performance at each forward and reverse speed setting. However, if drive system components have been replaced, adjustment may be necessary. Adjust as follows: 1. Move the ground speed control (A, Figure 19) fully forward. 2. Loosen the hardware (B) securing the upper and lower shift rods. 3. Push the lower rod (C) down fully (into the housing). 4.
Troubleshooting, Adjustments, & Service AUGER DRIVE SYSTEM ADJUSTMENTS Auger Drive Clutch Rod Auger Drive Clutch Rod Adjustment WARNING Auger Lever Do not over-tighten, as this may lift the idler rod lever and cause auger drive to be engaged without depressing the Auger Control. Adjustment Hex Nuts Auger Drive Clutch Rod Spring All auger drive adjustment is accomplished through the auger drive clutch rod.
Troubleshooting, Adjustments, & Service Belt Cover Screws Figure 22. Belt Cover Figure 23. Auger Pulley Belt Stops (shown with bottom cover removed) A. Nuts B. Belt Stops C. Auger Pulley BELT REPLACEMENT 1. Rotate the spout full right. Loosen the two screws (Figure 22) securing the belt cover. 2. Tilt the cover forward and work it off the snowthrower. 3. Remove the belt guide (B, Figure 24) by removing the two capscrews (A), lockwashers and washers. 4. Remove the auger drive belt as follows: a.
Troubleshooting, Adjustments, & Service 6. Reverse the procedure to install the belts. Be sure there are no twists and the belts are properly seated in the grooves. Adjust the belt stops so there is 1/8” (3mm) clearance between belt and stop. The pattern for both belts is shown in Figure 25. 7. Check the traction drive tension and auger drive tension. Follow the procedures under AUGER DRIVE BELT ADJUSTMENT. 8. Make sure the auger stops when the auger drive lever is released.
Troubleshooting, Adjustments, & Service DISCHARGE CONTROL ADJUSTMENT F A If the discharge chute is difficult to operate, first lubricate the pinion gear (A, Figure 27) and ring gear (F). If it is still difficult to operate, adjust as follows: E 1. Loosen the nut (G, Figure 27) which holds the pinion gear bracket in the slotted hole. 2. If the pinion gear is too tight against the ring gear, move it away slightly and then retighten the nut. B 3. Check the operation again. D C G Figure 27.
