• For temperatures above 32°F (0°C), use SAE 30. 7. Checking the Tire Pressure • For temperatures between 0°F and 32°F (-18°C to 0°C), use SAE 5W30 or SAE 10. Procedure • For air temperatures below 0°F (-18°C), use SAE 0W30. The tires are overinflated at the factory for shipping. Reduce the pressure equally in both tires to between 12 and 15 psi (83 and 103 kPa). 1. Move the snowthrower to a level surface to ensure an accurate oil level reading. 8. Checking the Skids and Scraper 2.
• Chute Deflector Handle—Move the deflector handle forward to move the snow stream down; move it rearward to move the snow stream up. • Fuel Shutoff Valve—Close the valve by rotating clockwise. Open the valve by rotating it counterclockwise. Close the valve when you do not use the snowthrower. • Choke—Move the choke to the (Full) position to start a cold engine. As engine warms up, gradually move the choke to the Off position. • Ignition Switch—Insert the key before starting the engine.
Figure 17 Removing the Carburetor Heater Box Figure 19 1. Green ground wire clip If you operate the engine when the air temperature is above 40°F (4°C), remove the carburetor heater box (Figure 18). 7. Install the choke knob. 8. Insert the ignition key. 9. Connect the wire to the spark plug. Important: Use the carburetor heater box as a reference for the choke and throttle positions.
Important: To reduce starting problems, add fuel stabilizer to the fuel all season, mixing it with gasoline less than 30 days old. Do not add oil to the gasoline. 1. Clean around the fuel tank cap (Figure 12). 2. Remove the fuel tank cap. 3. Fill the fuel tank with unleaded gasoline to within 1/4 to 1/2 (6 to 13 mm) from the top of the tank. Do not fill into the filler neck. 8.
Unclogging the Discharge Chute Operating Tips If the auger/impeller is running but there is no snow coming out of the discharge chute, the discharge chute may be clogged. When the snowthrower is in operation, the impeller and auger can rotate and cut off or injure hands and feet. • To unclog the discharge chute, stay in the operating position and release the left hand (traction) lever.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval After the first hour After the first 2 hours Before each use or daily Maintenance Procedure • Inspect and adjust the traction drive belt. • Inspect and adjust the auger/impeller drive belt. • Change the engine oil. • Check the engine oil level and add oil if necessary. • Inspect and adjust or replace the traction drive belt when necessary.
5. Read the oil level on the dipstick. 6. If the oil level is below the Add mark on the dipstick, slowly pour only enough oil into the filler hole to raise the oil level to the Full mark on the dipstick. Note: Use only a high-quality, SAE 5W-30 or SAE 10 weight detergent oil that has the American Petroleum Institute (API) service classification SF, SG, SH, or SJ.
4. Loosen the flange nuts that secure the selector plate to the control panel (Figure 23). 6. With the drive assembly 1/8 inch (3 mm) from the roll pin, tighten the flange nuts that secure the speed selector plate. 7. Shift the speed selector lever to the R (Reverse) position and back to third gear to check the adjustment. 8. If the space between the roll pin and the drive assembly is more than 3/16 inch (5 mm), repeat steps 3 through 6. 9.
Lubricating the Snowthrower Max. fill: 21 oz. (0.62 l), type: automotive detergent oil with an API service classification of SF, SG, SH, SJ, SL, or higher. Service Interval: Every 20 hours Yearly or before storage • For temperatures above 32°F (0°C), use SAE 30. Lightly lubricate all moving parts of the snowthrower after every 20 operating hours and at the end of the snowthrowing season. • For temperatures between 0°F and 32°F (-18°C to 0°C), use SAE 5W30 or SAE 10.
Figure 29 1. 0.030 inch (0.76 mm) 5. Install the spark plug by hand and then torque it to 15 ft-lb (20.4 N-m). Note: If you do not have a torque wrench, tighten the plug firmly. Figure 28 Adjusting the Traction Drive Belt Important: Do not excessively oil the snowthrower; extra oil may enter the traction drive and cause the traction drive belt to slip. Service Interval: After the first hour Before each use or daily 5. Wipe up any excess oil.
7. Disconnect the spring from the notch in the bottom edge of the side plate (Figure 32). Figure 30 1. Flange-head bolt (2) 2. Belt cover Figure 32 3. Loosen the belt guide (Figure 31). 1. Notch in side plate 2. Spring 3. Large traction pulley The spring is under heavy tension and could injure the you or a bystander if you do not carefully remove it. Carefully remove the spring. 8. Set the snowthrower upright. 9.
Replacing the Auger/Impeller Drive Belt and the guide, and secure the belt guide when the auger/impeller drive belt is tight. 18. Check the auger/impeller drive linkage and adjust it if necessary. Refer to steps 4 through 7 of Installing the Auger/Impeller Drive Control Linkage. If the auger/impeller drive belt becomes worn, oil-soaked, or otherwise damaged, replace the belt. 1. Remove the 2 flange-head bolts that hold the belt cover in place and set the cover aside (Figure 30). 2.
4. Open the fuel shutoff valve and allow the fuel to drain out of the fuel tank into the drain pan. 11. Pull the recoil starter slowly to distribute the oil on the inside of the cylinder. 5. Install the fuel line onto the fuel shutoff valve and secure it with a hose clamp. 12. Lubricate the snowthrower. Refer to Lubricating the Snowthrower. 6. Connect the wire to the spark plug. 13. Clean the snowthrower. 7. Start the snowthrower and run the engine until it stops.
Troubleshooting Problem Possible Cause Electric starter does not turn (electric-start models only) 1. The power cord is disconnected at the outlet or the snowthrower. 1. Connect the power cord to the outlet and/or the snowthrower. 2. The power cord is worn, corroded, or damaged. 3. The power outlet is not energized. 2. Replace the power cord. 1. The key is not in the ignition or is in the Stop position. 1. Insert the key into the ignition and turn it to the On position. 2.
Problem Possible Cause Corrective Action 7. The auger/impeller drive belt is worn or broken. 7. Replace the auger/impeller drive belt; refer to www.Toro.com for servicing information or take the snowthrower to an Authorized Service Dealer. Discharge chute either does not lock into place or does not move 1. The discharge chute latch is not properly adjusted. 1. Adjust the discharge chute latch. Snowthrower does not properly clear the snow off the surface 1.
