Do not put hands, feet, hair or loose clothing in or near the discharge chute deflector or auger housing while the engine is running. The temperature of the muffler and neaby areas may exceed 150 _ F.; avoid these areas also. Z_ WARNING: Objects such as gravel, rocks or other debris, if struck by the auger, may be thrown with sufficient force to cause personal injury or property damage. We recommend standard safety glasses or Wide Vision Safety Mask for over your glasses. SNOW THROWING TIPS WET • This snow thrower will propel itself forward when the handle is raised enough to cause the auger blades to contact the ground. The auger should stop when auger control bar is released. If it does not, refer to Adjust Auger Control Cable paragraph on page 12. PACKED • For most efficient snow throwing, turn the discharge chute deflector to throw snow downwind, and slightly overlap each swath. In light snow take up to a full cut and in heavy snow take less than a full cut. SNOW BANKS AND DRIFTS • In snow of greater depth than the unit, use the jabbing technique described above. Turn the discharge chute away from the snow bank. More time will be • The distance snow will be discharged can be adjusted by moving the discharge chute deflector. Raise the deflector for more distance or lower the deflector for less distance. required to remove snow of this type than level snow. PRODUCT SPECIFICATIONS HORSE POWER: 5HP • In windy conditions, lower the chute deflector to direct discharged snow close to the ground where it is less likely to blow into unwanted areas. DISPLACEMENT: • Keep the area to be cleared free of stones, toys and other foreign objects for safety and to prevent damage to the snow thrower. GASOLINE 8.46 cu. in. CAPACITY: 1.62 quart (unleaded) FUEL/OIL MIX RATIO: 40:1 • Do not use the auger propelling feature when clearing gravel or crushed rock driveways. Move the handle down to raise the auger slightly. • The allowable forward speed of the snow thrower is dependent on the depth and weight of the snow. Experience will establish the most effective method of using the snow thrower under different conditions. DRY AND AVERAGE SNOW • Move slowly into snow of this condition. The greater the depth, the slower you should go. When it appears that the wet, packed snow is causing the auger to slow down and the chute to clog, back off and begin a series of short jabs into the snow. These short back and forth, 4 to 6 inch, jabbing motions will "belch" the snow from the chute. SPARK PLUG: SNOW • Snow up to eight inch depth can be removed rapidly and easily by walking at a moderate rate. For snow or drifts of a greater depth you may find it desirable to slow your pace to allow the discharge chute to dispose of the snow as rapidly as the auger receives the snow. • Plan to have the snow discharged in the direction the wind is blowing. 10 (3.2 oz. of aircooled engine 2 cycle oil specified for 40:1 per 1 gal. of gas) Champion RCJ8Y (Gap .030) or Equivalent CUSTOMER RESPONSIBILITIES SCHEDULE SERVICE RECORDS Fill in dates as you complete regular service Before Each Use After first 12 Hours As Needed Before Storage SERVICE DATES Begin r Each Season Tighten All Screws & Nuts Check Spark Plug Check Drive Belts v,' Lubricate Chute Control Flange Check Fuel p,/ v" Drain Fuel GENERAL LUBRICATION RECOMMENDATIONS 4, The warranty on this snow thrower does not cover items that have been subjected to operator abuse or negligence.
