Resumen del manual
Always remove the ignition key before beginning any maintenance to prevent accidental starting of the engine. Locate the problem you have encountered in the Troubleshooting Chart. Check the possible causes one at a time in the order listed. Correct any problems that are found, and then operate the snowthrower to see if you have eliminated the problem. TROUBLESHOOTING CHART Problem Cause/Remedy 1. Snowthrower auger does not rotate. A FFO lever not engaged. Engage PTO lever. See Operation section. B. Foreign material or ice blocking auger. STOP engine. Remove kev. F'ree auger. C. Snowthrower drive belt slipping. Adjust drive belt tension. Sec Steps 10 and 17 in Installation section. D. Drive chain broken. Replace parts as necessary. 2. Auger rotates, but snow not thrown far enough. A Engine RPM too slow. Operate engine between 3/4 and full throttle. B. Ground speed too fast. Use lower gear. C. Snowthrower discharge chute dogged. STOP engine. Remove key. Clear discharge chute. 3. Scraper bar does not clean down to hard surface. Skid shoes not properly adjusted. Adjust skid shoes. Sec Adjustments section. 4. Snowthrower picks up and throws stones on gravel drive. A. Skid shoes not properly adjusted for gravel surface. Adjust skid shoes. See Adjustments section. B. Too much down pressure on snowthrower. Use the tractor lift lever to raise the snowthrower slightly. See Operation section and Adjustment section. 5. Tractor does not have sufficient traction. Tractor too light at rear wheels. Use counterweights and tire chains. 6. Ttactor not stable on sloping surfaces. A. Ground speed too fast. Reduce ground speed. B. Tractor not properly weighted. Use counterweights and tire chains. C. Tire pressure incorrect. For operation with snowthrower. increase front tire pressure to 20 psi (138 kPa). For operations without snowthrower. see Tractor Owner's Manual for required pressure. 7. Auger does not stop when PTO is disengaged, Belt tension not properly adjusted. Adjust belt tension. See Steps 10 and 17 in Installation section. 21 ADJUSTMENTS SKID SHOE ADJUSTMENT For a smooth, hard surface such as concrete or asphalt, adjust the skid shoes so that the scraper bar rests on the surface. For a rough surface, such as gravel, adjust the skid shoes so that the scraper bar rides slightly above the surface and does not pick up debris. To adjust, rest each side of the scraper bar on wood blocks about one inch (25 mm) high, with scraper bar level with surface. Loosen the two nuts holding each skid shoe and move the skid shoes up and down. Tighten the nuts securely, with both skid shoes adjusted to same level and parallel to surface. LOOSEN KNOB TO ADJUST DEFLECTOR HEIGHT LOOSEN NUTS TO ADJUST SKID SHOE SCRAPER BAR DEFLECTOR ADJUSTMENT The position of the deflector determines the height and distance snow will be thrown. Most snow throwing can be done with the deflector all the way up. To adjust, loosen the knob and move the deflector up or down. Retighten the knob. LIFT ROD ADJUSTMENT The front set collar affects the transport clearance between scraper blade and ground. Moving set collar toward spring will increase clearance. See initial setting in Installation section. The rear set collar affects how the snowthrower will float over surface bumps or dig into them. Perform step “a” to allow snowthrower to float or step “b" to increase ‘‘down pressure.” a. Fully raise the snowthrower. Loosen the setscrews in the rear set collar. Move the set collar back away from spring. The farther back the set collar is moved, the more the scraper blade will float. Tighten the setscrews. b. Fully lower the snowthrower lift lever. Loosen the setsc rews in the front set collar and slide it off the lift rod. Pull the lift lever back slightly so lift rod moves back one inch. Place the spring against the rod guide. Place the rear set collar against the spring and tighten the setscrews. Fully lower the lift lever. Notice that the spring is now compressed to provide down pressure. (Spring should compress about two inches. Do not allow spring to go solid.) Place the front set collar on the rod and adjust as follows: Adjust front set collar so there is 10 mm (0.39 in.) between guide and collar.
