Features, Controls, & Operation Please take a moment and familiarize yourself with the name, location, and function of these controls so that you will better understand the safety and operating instructions provided in this manual. ALL MODELS 1,2..
Features & Controls CONTROL LOCATIONS The information below briefly describes the function of individual controls. Starting, stopping, and driving require the combined use of several controls applied in specific sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section. 1,2.. Speed Selector Fuel Selects forward speeds 1-5 and reverse speeds 1-2. Fuel tank filler cap (see illustration). The fuel shut off valve is located under the fuel tank.
Engine Controls STARTING CONTROLS Tecumseh Models See Figure 1 for the following instructions. Units with Optional Electric Start A B A. Electric Start Button - The Electric Start Button (A) 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.
Controls GROUND SPEED CONTROLS A C A. Speed Selector - This lever (A, Figures 2 & 3) 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 WARNING CHECKS BEFORE EACH START-UP This unit is a “two-stage” snowthrower. 1. Make sure all safety guards are in place and all nuts, bolts and clips are secure. 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. If bodily contact is made with the auger or impeller when they are rotating, severe personal injury will occur. 2. Check the engine oil level.
Operation STARTING THE ENGINE Tecumseh Models Refer to Figure 4. 1. Turn the fuel valve (B) to the ON position. A B 2. Insert the engine key (F) into the engine key slot. 3. Move the throttle lever (E) to the FAST position. C 4. Fully close the choke (G) if engine is cold (a warm engine may not require choking). 5. Push the primer button (D) two times if engine is cold (a warm engine may not require priming). 6.
Operation OPERATING THE SNOWTHROWER C 1. Rotate the discharge chute to the desired direction. A D B 2. Set the speed selector to the desired forward speed. 3. Fully press and hold the auger control (C, Figure 5) on the right-hand grip to begin auger rotation. To disengage the auger, completely release the lever. 4. Fully press and hold the traction drive control lever (B, Figure 5) on the left-hand grip to engage the traction drive and begin moving the snowthrower.
Operation DEFLECTOR Chute Deflector Knob The distance of the discharged snow is mainly controlled by the position of the deflector (Figure 7). (Engine speed also affects distance of discharge.) The more the deflector is tilted UP, the farther snow will be thrown. Loosen the deflector knob, tilt the deflector UP or DOWN, and then retighten the knob when the desired angle has been chosen. Chute Deflector Figure 7.
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 9 & 10). Klik-Pin In OUTER Hole 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 9). 3.
Maintenance SCHEDULE 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 Yearly Lithium Grease Clean or replace spark plug.✛ Check drive linkage/belt tension Lubricate Axle Shafts * Change original oil after two hours of operation.
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. Remove wheels and grease axles once each year. There are two grease fittings on the auger shaft. Wipe the fittings clean and apply grease, using a grease gun.
Storage CHECK / LUBRICATE FREE-HAND LINKAGE WARNING Never store the unit, with gasoline in engine or fuel tank, in a heated shelter or in enclosed, poorly ventilated enclosures. Gasoline fumes may reach an open flame, spark or pilot light (such as a furnace, water heater, clothes dryer, etc.) and cause an explosion. Check the function of the Free-Hand controls: the controls should function as described in the CONTROLS section.
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 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. 5.
Adjustments 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 18) 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.
Adjustments 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. The rod must be adjusted so that there is 1/32” clearance between the spring hook and the auger lever (see Figure 20).
Adjustment DISCHARGE CHUTE PINION ADJUSTMENT F A If the discharge chute is difficult to operate, first lubricate the pinion gear (A, Figure 21) and ring gear (F). If it is still difficult to operate, adjust as follows: E 1. Loosen the nut (G, Figure 21) 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 21. Discharge Control A. Pinion Gear E.
Service Belt Cover Screws Figure 23. Belt Cover Figure 24. Auger Pulley Belt Stops (shown with bottom cover removed) A. Nuts C. Auger Pulley B. Belt Stops BELT REPLACEMENT 1. Rotate the spout full right. Loosen the two screws (Figure 23) securing the belt cover. 2. Tilt the cover forward and work it off the snowthrower. 3. Remove the belt guide (B, Figure 25) by removing the two capscrews (A), lockwashers and washers. 4. Remove the auger drive belt as follows: a.
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 26. 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.
