Make certain the auger and drive controls are in the disengaged (up) position. Move throttle control up to FAST position. Insert ignition key into slot and snap in place. See Figure 5. Do not turn key. NOTE: Engine will not start unless ignition inserted into ignition slot in carburetor cover.
ToEngage Augers Clean-OutTool • The clean-out tool is conveniently fastened to the rear of the auger housing with a mounting clip. Should snow and ice lodge itself in the chute assembly during operation, proceed as follows to safely clean the chute and chute opening: To engage the augers and start throwing snow, squeeze the auger control against the left handle. Release to stop the augers.
Operating Tips • • • NOTE: Allow the engine to warm up for a few minutes. The engine will not develop full power until it reaches operating temperature. and the surrounding areas may exceed WARNING: The temperature of the muffler 150°F. Avoid these areas. • • • For the most efficient snow removal, remove snow immediately after it falls. Discharge the snow downwind whenever possible. Slightly overlap each previous path. Set the skid shoes 1/4" below the shave plate for normal usage.
If adjustment is necessary: • • • • Loosen the jam nut on the drive cable. Adjust the cable as necessary. Refer to Figure 7. Retighten the jam nut to secure the cable when correct adjustment is reached. Reassemble the frame cover. Reconnect the upper shift rod to the lower shift rod by reinserting the hairpin clip removed earlier and sliding the shift rod connector back down into place.
SECTION6: MAINTAININGYOURSNOWTHROWER WARNING: Before lubricating, repairing, or inspecting, disengage all controls and stop engine. Wait until all moving parts have come to a complete stop. Disconnect spark plug wire and ground it against the engine to prevent unintended starting. Always wear safety glasses during operation or while performing any adjustments or repairs. is free of grease in order to relieve pressure. Auger Shaft At least once a season, remove the shear bolts on the auger shaft.
Augers • • • The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. If you hit a hard foreign object or ice jam, the snow thrower is designed so that the bolts may shear. Refer to Figure 13. If the augers will not turn, check to see if the bolts have sheared. Replacement shear bolts and hex lock nuts have been provided with the snow thrower. When replacing bolts, spray an oil lubricant into shaft before inserting new bolts.
• • Support • Auger Support Remove six self-tapping screws from the frame cover underneath the snow thrower. Using a 7/8" wrench to hold the shaft, loosen, but do not completely remove, the hex bolt and bell washer on the left end of gear shaft. See Figure 19. Lightly tap the hex nut to dislodge the ball bearing from the right side of frame before removing the hex nut and bell washer from left end of shaft.
• • • • Remove the four screws from the friction wheel assembly. See Figure 20. Remove the friction wheel rubber from between the friction wheel plates. Reassemble new friction wheel rubber to the friction wheel plates and hub, tightening the four screws in rotation and with equal force. Position the friction wheel assembly up onto the pin of the shift rod assembly, and slide the shaft through the assembly. Reassemble in reverse order.
