• Exercise caution to avoid slipping or falling, especially when operating the snowthrower in reverse. This manual identifies potential hazards and has special safety messages that help you and others avoid personal injury and even death. Danger, Warning, and Caution are signal words used to identify the level of hazard. However, regardless of the hazard, be extremely careful.
• Stop the engine whenever you leave the operating position, before unclogging the auger/impeller housing or discharge chute, and when making any repairs, adjustments, or inspections. • Always refer to this operator’s manual for important details if the snowthrower is to be stored for an extended period. • Maintain or replace safety and instruction labels when necessary. • When cleaning, repairing, or inspecting, make certain that the auger/impeller and all moving parts have stopped.
Sound Power Level from accidentally starting the engine. If major repairs are ever needed, contact your Authorized Service Dealer. • Do not change the governor settings on the engine. This unit has a sound power level of 106 LwA, based on measurements of identical machines per Directive 84/538/EEC. • When storing the snowthrower for more than 30 days, drain the fuel from the fuel tank to prevent a potential hazard. Store fuel in an approved fuel container.
Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger.

Remove the two flange bolts and flat washers that secure the ends of the scraper to the side plates (Fig. 10). Note: The scraper should be higher than 1/8 inch (3 millimeters) above the pavement if it is cracked, rough, or uneven. Setting the scraper too low may result in damage to the snowthrower that is not covered by the warranty.
1 Danger 2 In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, and when the engine is cold. Wipe up any gasoline that spills. • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 in. (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows the gasoline to expand.
• Traction Control Lever (Fig. 13)—To engage the traction (wheel drive), press the lever against the left handgrip. To stop the traction, release the lever. 2. Remove the fuel tank cap. 3. Fill the fuel tank with unleaded to within 1/4 to 1/2 inch (6 to 13 millimeters) from the top of the tank. Do not fill into the filler neck. • Speed Shift Control (Fig. 13)—This control has a neutral position, four forward speeds, and two reverse speeds. It also controls the power shifting of the wheels.

Starting the Engine Important Ensure that there are no obstructions in the auger/impeller and the discharge chute before you operate the snowthrower. Use a stick, not your hand, to remove an obstruction from the auger/impeller or the discharge chute. 1. Connect the wire to the spark plug. 2. Move the speed shift control to the N (Neutral) position and the throttle to the Fast position. 3. Release the auger/impeller drive control lever and the traction control lever (Fig. 13). 1 m-2680 Figure 20 4.

Note: When shifting, you may need to slightly raise the handle assembly to assist the wheel movement. 3. Axle pin Adjusting the Headlight 1. Loosen the two nuts on the U-bolt that hold the headlight bracket to the handle (Fig. 24). 179 Figure 22 5 4. Release the speed shift control.
• In wet or slushy conditions, maintain maximum engine speed, and do not overload the engine to prevent clogging the discharge chute. Snowthrowing Tips Danger • If the front of the snowthrower tends to ride up, reduce the forward speed by shifting the snowthrower into a lower gear. If the front still tends to ride up, lift up on both handgrips to hold down the front of snowthrower. When the snowthrower is in operation, the impeller and auger can be rotating and cut off or injure hands and feet.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Initially • Check the engine oil level.1 Refer to Checking the Engine Oil Level on page 19. • Check the auger gearbox oil level and add oil if necessary. Refer to Checking the Auger Gearbox Oil Level on page 19. • Adjust the skids and the scraper.2 Refer to Adjusting the Skids and the Scraper on page 20.
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 1. Stop the engine and wait for all moving parts to stop. 2. Move the snowthrower to a level surface.
Adjusting the Skids and the Scraper 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. 30). 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 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. 31). If the auger/impeller drive belt or the traction drive belt (Fig. 31) becomes worn, oil-soaked, or otherwise damaged, replace the belt. 5 11. Install the traction drive belt on the idler pulley (Fig. 31). 6 7 4 12.
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. 1 186 Lubricating the Drive Chain Figure 34 1. 1/8 to 3/8 in. (3 to 10 mm) deflection Lightly lubricate the drive chain after every 15 operating hours and at the end of the snowthrowing season. 1. Disconnect the wire from the spark plug and ensure that the wire does not contact the plug (Fig. 25). 8.
13. Check the speed shift control alignment with the Power Shift slot. If the gear shift lever does not align with the Power Shift slot in the control panel (see inset in Fig. 6), adjust the shift rod length as follows: Danger Gasoline is highly flammable; it can ignite and cause serious personal injury. A. Disconnect the ball joint from the transmission lever and loosen the jam nut. • • • • Drain gasoline outdoors. Drain gasoline from a cold engine only. Wipe up any gasoline that may have spilled.
5. Choke or prime the engine, start it a third time, and run the engine until it will not start. 6. Dispose of unused fuel properly. Recycle it according to local codes, or use it in your automobile. Note: Do not store stabilized gasoline for more than 90 days. Preparing the Engine 1. While the engine is still warm, change the engine oil. Refer to Changing the Engine Oil on page 22. 2. Remove the spark plug. 3. Use an oil can to squirt two teaspoons of oil into the spark plug hole. 4.
Troubleshooting Toro designed and built your snowthrower for trouble-free operation. Check the following components and items carefully, and refer to Maintenance on page 18 for more information. If a problem continues, see an Authorized Service Dealer. Problem Electric starter does not turn (electric-start models only) Engine does not start or starts hard Engine runs rough Possible Causes Corrective Action 1. The power cord is disconnected at the outlet or the snowthrower. 1.
Problem Engine runs, but the snowthrower discharges snow poorly or not at all Snowthrower does not properly clear the snow off the surface Possible Causes Corrective Action 3. The fuel tank is nearly empty or contains stale fuel. 3. Drain and fill the fuel tank with fresh gasoline (not more than 30 days old). If the problem persists, contact an Authorized Service Dealer. 4. The spark plug wire is loose. 4. Connect the wire to the spark plug. 5.
