Caution If you leave the wire on the spark plug, someone could accidently start the engine and seriously injure you or other bystanders. Disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Checking the Engine Oil Level 2. Move the snowthrower to a level surface. 3. Disconnect the wire from the spark plug and ensure that the wire does not contact the spark plug (Fig. 24).
Adjusting the Skids and the Scraper For Gravel Surfaces: Support the auger blades a few inches (centimeters) above the ground, and adjust the skids to prevent the snowthrower from picking up rocks. Adjust the skids and the scraper initially and then as needed to ensure that the auger does not contact the paved or gravel surface. Also, adjust them as needed to compensate for wear. 8. To adjust the scraper, loosen the carriage bolts that secure the scraper to the auger housing (Fig.
Note: With the lever released, there should be at least 1/8 in. (3 mm) clearance between the tab on the impeller idler arm and the brake arm (Fig. 29). Important Do not adjust the belt too tightly; a tight belt can cause the snowthrower to creep even after you release the traction control lever. If this occurs, decrease the belt tension.
Replacing the Drive Belts Note: The cable must slide freely in the bracket when you change the belts. If the auger/impeller drive belt or the traction drive belt (Fig. 30) becomes worn, oil-soaked, or otherwise damaged, replace the belt. 5 10. If you replace the traction drive belt, install it around the traction drive and the middle pulley section, and slide the middle pulley section onto the crankshaft (Fig. 30). 6 7 4 11. Install the traction drive belt on the idler pulley (Fig. 30). 12.
7. Check the deflection of the chain by lifting up on it with moderate pressure at the mid span. There should be a 1/8 to 3/8 in. (3 to 10 mm) deflection (Fig. 33). 5. Drain the oil. 6. Install the oil drain plug. 7. Fill the crankcase with oil. Refer to Filling the Engine Crankcase with Oil on page 11. 8. Wipe up any spilled oil. 9. Connect the wire to the spark plug.
