WARNING: The muffler, engine, and their surrounding areas become hot and can cause a burn. Do not touch. • Discharge snow downwind whenever possible. Slightly overlap each previous swath. • Set the skid shoes 1/4" below the scraper bar for normal usage. The skid shoes may be adjusted upward for hard-packed snow. Adjust downward when using on gravel or crushed rock. • Avoid possible starter freeze-up. Clean the snow thrower thoroughly after each use. Carriage Screws / Hex Nuts Drift Cutter 14 SECTION 6: MAKING ADJUSTMENTS WARNING: Never attempt to make any adjustments while the engine is running, except where specified in operator’s manual. Tire Pressure (Pneumatic Tires) • The tires are overinflated for shipping purposes. Before operating check tire pressure and reduce pressure to between 15psi and 20 psi. NOTE: If the tire pressure is not equal in both tires, the unit may pull to one side or the other. Traction Control and Shift Lever • To check the adjustment of the traction control clutch and shift lever, proceed as follows: • With the engine off, move the shift lever all the way forward to the highest speed. With the traction control lever released, push the snow thrower forward. The unit should roll forward. Then engage the traction control grip. The wheels should stop turning. • Now release the traction control grip and push the unit again. • Move the shift lever back to the fast reverse position then all the way forward again. There should be no resistance in the shift lever, and the wheels should keep turning. • If you have resistance when moving the shift lever or the wheels stop when they should not, loosen the jam nut on the traction control cable and unthread the cable one turn. • If the wheels do not stop when you engage the traction control clutch grip, loosen the jam nut on the traction control cable and thread the cable in one turn. • Recheck the adjustment and repeat as necessary. Tighten the jam nut to secure the cable when correct adjustment is reached. WARNING: Drain the gasoline out of snow thrower engine, place a piece of plastic film under the gas cap to avoid spillage before beginning the job. To test further for correct adjustment, if necessary, proceed as follows: • Tip the snow thrower so that it rests on the auger housing. See Figure 17. • Remove the frame cover underneath the snow thrower by removing six self-tapping screws. • When the traction control is released, there must be clearance between the friction wheel and the drive plate in all positions of the shift lever. Figure 17 • With the traction control is engaged, the friction wheel must contact the drive plate. See Figure 18. Figure 18 If adjustment is necessary. • Loosen the jam nut on the traction control cable and thread the cable in or out as necessary. • Retighten the jam nut to secure the cable when correct adjustment is reached. • Reassemble the frame cover. NOTE: If you placed plastic under the gas cap earlier, remove it now. Frame Cover Auger Housing Friction Wheel Gear Shaft Drive Plate Gap 15 Chute Assembly The distance snow is thrown can be adjusted by changing the angle of the chute assembly. To do so, stop the engine by removing the ignition key and loosen the plastic wing knobs found on either side of the discharge chute. Pivot the chute upward or downward before re-tightening the wing knobs. Auger Control Refer to Auger Control Test in the Operating Section to adjust the auger control. Skid Shoes The space between the shave plate and the ground can be adjusted. See Figure 19. • For close snow removal on a smooth surface, raise skid shoes higher on the auger housing. • Use a middle or lower position when the area to be cleared is uneven. Figure 19 WARNING: Do not operate this snow thrower on gravel as loose gravel can be easily picked up and thrown by the auger causing injury to the operator and/or damage to the snow thrower. • Adjust skid shoes by loosening the four hex nuts and carriage bolts. Move skid shoes to desired position. • Make certain the entire bottom surface of skid shoe is against the ground to avoid uneven wear on the skid shoes. Retighten nuts and bolts securely. Carburetor • Minor carburetor adjustment may be required to compensate for differences in fuel, temperature, altitude and load. • Refer to the separate engine manual, packed with your unit, for carburetor adjustment information. WARNING: If any adjustments need to be made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of muffler, engine and other surrounding heated surfaces. Adjusting Shift Rod • Remove the hairpin clip and flat washer from the ferrule and remove the ferrule from the shift lever. Place the shift lever in the fastest forward speed position. Models 602, 642, 662 • Push up on the shift arm assembly as far as it will go. Thread the ferrule up or down the shift rod and align with the lower hole on the wider side of the shift lever assembly behind the handle panel....
