Anleitung Zusammenfassung
Detach cable from receptacle and engine. On jump start equipped models, refer to instructins provided in kit. NOTE: If engine does not start after five seconds of continuous cranking, release electric start button to prevent overheating of the starting motor. Locate and correct cause of starting problem before repeating electric starting attempt. WARM-UP PERIOD: Allow brief warm-up outside with clutches released to avoid stalling cold engine. Reset Choke as instructed in Engine Manual as the unit warms up. OPERATION: Select desired traction speed by adjusting DIRECTION CONTROL LEVER, depress TRACTION CLUTCH handle and drive unit to area to be cleared then depress BLOWER CLUTCH handle and proceed to blow snow. The THROTTLE CONTROL should normally be in the FAST position for best result under most conditions. CAUTION: If clogging occurs, back unit away from snow bank, release both CLUTCH handles and, as a further precaution, stop the engine and remove spark plug wire before clearing the snow from the housing and/or discharge chute. BEFORE STOPPING: Move unit to cleared area, release TRACTION CLUTCH handle and run up to top speed with BLOWER CLUTCH HANDLE depressed to clear housing of slush and snow thus preventing freeze-up of the impeller upon restarting next time. STOPPING PROCEDURE: On all units, remove the key to stop engine or move the THROTTLE CONTROL to OFF or STOP. FIGURE 2 - GREASE FITTING LOCATIONS SERVICE PROCEDURE LUBRICATION SERVICES Refer to the Engine Manual for lubrication requirements on the engine powering your Snow Thrower. Your Snow Thrower unit has six grease fittings, four on the collector augers and two on the auger shaft bearings as shown in Fig. 2. The unit also has a lube checkpoint at the front of the gearbox shown in FIG. 3. Service these and the other general lube points as follows: AUGER LUBRICATION: ONCE EACH YEAR, preferably at the end of the winter season, remove the two shear bolts, apply grease to the fittings then spin the auger to work the grease out along the auger shaft. Continue greasing and spinning augers until grease appears at both ends of each auger tube. Reinstall shear bolts and nuts after servicing. This procedure will prevent the auger shaft from rusting to the auger tube. Refer to FIG. 2. BEARING LUBE: ONCE EACH YEAR, apply one or two shots of grease from gun to the bearing grease fittings located at the ends of the auger shaft just inside the blower housings. Refer to FIG. 2. GENERAL LUBE POINTS: ONCE EACH YEAR, or more often if rust formation hampers operation, spread a light coating of grease on the chute crank worm and on the underside of the gear ring at the base of the discharge chute. Also squirt oil from oil can into the gap between the inside of the discharge chute and the outside of the discharge flange of the blower housing. Crank chute back and forth while oiling to spread lubrication evenly over both surfaces. Although not absolutely necessary, you may want to remove each wheel at the end of the season and apply a coating of grease on the axle shafts to prevent rust and allow the wheels to be moved more easily from transport to traction mode during the next season. GEARBOX LUBE: AFTER EACH 25 HOURS of operation (or each time the engine oil level is checked) remove the plug at the front of the gearbox and check the oil level. 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 FIG. 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. Retlghten inside nut first then jam the outside nut tight against the inside nut to lock at the new setting. 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...
