+ See your engine Owner’s Manual. ***Lubricate each fall and spring. CHECKING TIRE PRESSURE The air pressure in each tire (Figure 8) should be equal for both tires for best performance. Be sure to keep caps on valves to prevent entry of debris into the valve stem when tires are filled. Size PSI bar 15x5.0-6 20 1,38 4.80-8 20 1,38 16 x 6.5-8 14 ,96 AUGER GEAR CASE LUBRICATION 1. Place the snowthrower on a level surface. 2. Remove the pipe plug (A, Figure 9). 3. Check the lubricant level. It should be level with the lower edge of the plug opening. If not, add The Dealer Line Winter Weight Worm Gear Oil (available from your dealer). 4. Re-install pipe plug, and tighten securely. Figure 9. Auger Lubrication A. Pipe Plug 16 Regular Maintenance LUBRICATION IMPORTANT NOTE It is very important that grease fittings on the auger shaft are lubricated regularly. If auger rusts to shaft, damage to worm gear may occur if shear pins do not break. To prevent wheels rusting to axles, it is also necessary to remove the wheels and grease the axles regularly. Remove wheels and grease axles once each year. Apply medium weight (10W) oil to points shown (See Figures 10-13). Apply 5W-50 synthetic motor oil to the friction disk drive hex shaft (A, Figure 11). Generally, all moving metal parts should be oiled where contact is made with other parts. Keep oil and grease off belts, pulley grooves, drive disc, and friction disc. LUBRICATION NOTES: Grease locations indicated by grease gun symbol. Use grease fittings when present. Disassemble parts to apply grease to moving parts when grease fittings are not installed. | Oil locations indicated by oil can symbol. Do not I allow oil to drip onto traction drive or friction disc. Do not lubricate remote deflector control. Figure 11. Drive Lubrication A. Hex Shaft Figure 12. Grease Axles & Lubricate Control Levers (Channel Handle Model Shown) 17 Regular Maintenance CHECK/LUBRICATE FREE-HAND LINKAGE Check the function of the Free-Hand controls: the controls should function as described in the CONTROLS section. It is critical for the safe operation of the unit that the controls disengage when released. If the controls do not function properly, lubricate them. If lubrication does not rectify the problem, see your dealer. Under no circumstances should the unit be used if the controls are not functioning properly. LUBRICATING THE AUGER SHAFT & ASSEMBLY 1. Remove cotter pin (C, Figure 16) and shear pin (B). 2. Use a grease gun and squirt several shots of grease into grease fitting (A). 3. Rotate auger assembly (D) several times to distribute the grease evenly. Repeat step 2. 4. Reinstall shear pin (B) and cotter pin (C). 5. Repeat procedure for other side. Figure 14.

Locate the problem and check the possible cause/remedy in the order listed. Also, refer to the engine manufacturer’s Owner’s Manual for additional information. For problems not covered here, contact your local dealer. A WARNING Before performing any adjustment or service to snowthrower, stop the engine and wait for moving parts to stop. Remove the key. To prevent accidental starting, disconnect the spark plug wire and fasten away from the plug. PROBLEM POSSIBLE CAUSE REMEDY Engine fails to start. 1. Key is OFF. 1. Push key in to the ON position. 2. Failure to prime cold engine 2. Press primer button twice and restart. 3. Fuel valve is in CLOSED position. 3. Turn valve to OPEN position. 4. Out of fuel. 4. Fill fuel tank. 5. Choke OFF - cold engine. 5. Turn choke to ON, set throttle to FAST. 6. Engine flooded. 6. Turn choke to OFF; try starting. 7. No spark. 7. Check gap.
