7. Clean around the oil filler cap/dipstick (Figure 24). 8. Unscrew the oil fill cap/dipstick and remove it (Figure 24). 9. With the snowthrower in the operating position, carefully pour oil into the oil fill hole until "Full" on the fill cap/dipstick line (Figure 26). Max fill: 18 oz. (0.5 l), type: automotive detergent oil with an API service classification of SJ, SL, or higher. Use Figure 25 below to select the best oil viscosity for the outdoor temperature range expected: Figure 24 1. Oil fill cap/dipstick 1 1 Figure 25 NOTE: 10W30 synthetic oil is acceptable for use in cold temperatures. 10. Screw in the oil fill cap/dipstick and hand tighten it securely. 11. Wipe up any spilled oil. 12. Dispose of the used oil properly at a local recycling center. The engine oil will be hot. Avoid skin contact with the used engine oil. Figure 23 1. Oil drain plug 1 1. Move snowthrower to a level surface. 2. Run snowthrower until all fuel has been depleted. 3. Remove ignition key.

Stop the engine and wait for all moving parts to stop. 2. Rotate the discharge chute so that it faces forward. 3. Remove the discharge chute, the discharge chute handle by removing the three carriage bolts and flange nuts (Figure 27). 4. Remove the six screws that secure the shroud assembly (Figure 28). 5. Remove the oil fill cap. 6. Remove the shroud assembly (Figure 28). 7. Install the oil fill cap. 8. Disconnect the spark plug wire from the spark plug (Figure 29). 9. Clean around the spark plug. 10. Remove the spark plug from the cylinder head. IMPORTANT: Replace a cracked, fouled, or dirty spark plug. Do not clean the electrodes because grit entering the cylinder can damage the engine. 11. Set the gap on the plug to 0.030 inch (0.76 mm) (Figure 30). 12. Install the spark plug and torque it to 20–22 ft-lb (27–30 N-m). 13. Connect the spark plug wire to the spark plug (Figure 29). 14. Remove the oil fill cap. 15. Install the shroud with the screws removed in step 4 (Figure 28). NOTE: Ensure that the shroud assembly fits together in the side grooves. 16. Install the oil fill cap. 17. Install the discharge chute, and the discharge chute handle onto the snowthrower using the hardware removed in step 3 (Figure 27). 1.

Remove the drive side cover by removing the six screws as shown in (Figure 31). 2. Press down on front of idler arm to release the belt tension (Figure 31). 3. Remove the drive belt from the drive pulley (Figure 31). 4. Install the new drive belt, routing it as shown in (Figure 32). NOTE: Route the new drive belt first around the engine pulley, then the idler pulley, and finally around the drive pulley while pressing down on the front of the idler arm. (Figure 32). 5. Install the drive side cover with the screws removed in step 1. NOTE: Ensure that the drive belt is properly adjusted and operating; refer to Checking the Control Cable and Adjusting the Control Cable in the Maintenance section of this manual. 1.

WARNING: Never store the snow thrower with gaso line in the tank in side a build ing where fumes may reach an open flame, spark or pilot light as on a fur nace, water heater, clothes dryer or gas ap pli ance. Allow the engine to cool be fore storing in any enclosure. SNOW THROWER When snow thrower is to be stored for a period of time, clean it thor oughly, re move all dirt, grease, leaves, etc. Store in a clean, dry area. 1. Clean entire snow thrower after each use. 2. Inspect and replace belts, if necessary (See “Replaceing the Drive Belt” sec tion of this manual). 3. Be sure that all nuts, bolts, screws, and pins are securely fas tened. Inspect moving parts for damage, breakage and wear. Replace if nec es sary. 4. Touch up all rusted or chipped paint surfaces; sand lightly before painting. FUEL SYS TEM IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor, fuel hose, or tank during storage. Also, alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel...
