Resumen del manual
With the Thrower on a flat, level surface, the oil should be even with the lower edge of the check hole. Use an oil can containing the same weight and grade of oil specified for the engine crankcase to bring the level up to the point of overflowing from the hole. Reinstall the oil plug after servicing. CHUTE CRANK SERVICE If the chute does not crank easily after lubricating as specified under GENERAL LUBE SERVICES, loosen both nuts on the outside of the crank worm bracket as shown in figure 4 and move the bracket slightly away from the chute gear ring or back in toward the ring until the chute again cranks with minimum effort. Retighten inside nut first then jam the outside nut tight against the inside nut to lock at the new setting. 5 BELT SERVICE Belts do not require attention at any specific interval but should be checked if performance deteriorates as this could be caused by slippage due to worn or loose belts. Check and adjust tension of clutch cables first as described in the CLUTCH ADJUSTMENT section then check the belts if poor performance continues after clutch cable tension has been corrected. Make sure the engine is stopped and the spark plug wire disconnected before working on the belts. NOTE: Blower rotation should cease within five seconds after the clutch handle is released. If rotation continues after five seconds, cable may be too tight. If readjusting the cable does not correct the stopping time, check to make sure the idler return spring is connected and that the idler is properly set. See your Snapper Dealer to have this condition corrected. BELT TENSION: Tension on the traction drive belt is automatically maintained by an individual idler spring. After removing the belt guard, check to make sure this spring is intact and properly hooked up to the frame and idler arm. If the spring is prdperly connected, check for excessively worn belts. Notice the return spring on the idler for the blower drive - this spring activates the brake. The idler should always return to braking position! Tension of the blower drive belt, which is on the outside groove of the engine drive pulley, is adjusted by loosening and repositioning the idler pulley--to increase tension, loosen the idler pulley retaining nut, hold the idler arm and push the pulley tighter against the belt. Retighten nut after repositioning and check for proper clutching action with blower clutch handle released. Tension of the traction belt on the inside groove is non-adjustable. Before reinstalling belt guard check to make sure the wire belt guide on the right side is about 1/16" away from the outside surface of the blower belt with clutch engaged. Bend the guide in or out to correct clearance. CLUTCH CABLE ADJUSTMENT If slippage is noted, check tension of both clutch cables. When properly adjusted, the cables should be completely slack with clutch handle released and tight when the handle is fully depressed. The springs on both cables should deflect 3/8" when the handle is depressed. To adjust shorten or lengthen cable length by repositioning the "S" hooks at top of the cable to different chain links. SKID SHOE ADJUSTMENT The skid shoes should be lowered to raise the blower housing to clear gravelled or rough surfaces, or adjust until almost even with the edges of the housing to allow clearing down to smooth paved surfaces. Note that the skid shoes can be installed upside down to track better over icy or hard-packed surfaces. To adjust the skid shoes,"block under the lower edge of the blower housing, loosen the retaining nuts and slide shoe up or down to desired height then retighten the nuts. Set both skid shoes in the same position. 6 FIGURE 9 - SCRAPER BLADE ADJUSTMENT SCRAPER BLADE Your Snow Thrower is equipped with an adjustable scraper on the inside leading edge of the collector housing. Its purpose is to prevent wear and damage to the housing. When the scraper itself wears down close to the lower edge of the housing, loosen the five nuts on the backside of the housing and slide the scraper downward, ftetighten the five nuts after repositioning. Replace the scraper if badly nicked or when it no longer can be adjusted below the edge of the housing.
