• 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.
• Maintain or replace safety and instruction labels when necessary. • 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. • Run the engine run for a few minutes after clearing the snow to prevent the auger/impeller from freezing. • When cleaning, repairing, or inspecting, make certain that the auger/impeller and all moving parts have stopped.
• 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. Remove the key from the ignition switch before storing the snowthrower. Sound Power This unit has a guaranteed sound power level of 110 dBA, based on measurements of identical machines per Directive 2000/14/EC. • To ensure the best performance and safety, purchase only genuine Toro replacement parts and accessories.

Support the scraper 1/8 inch (3 millimeters) above a level surface if you use the snowthrower on smooth pavement. 4. Slowly pour about 3/4 of the crankcase capacity of oil into the crankcase. Note: The scraper should be higher than 1/8 inch (3 millimeters) above the pavement if it is cracked, rough, or uneven.
Important days old. Important Do not use fuel additives other than a fuel stabilizer/conditioner. Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol. Do not use gasoline that is more than 30 Danger 1. Clean around the fuel tank cap (Fig. 12). 2. Remove the fuel tank cap. 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. 3.
Operation 4 Note: Determine the left and right sides of the machine from the normal operating position. Operating Controls 3 • Auger/Impeller Drive Control Lever (Fig. 13)—To engage both the auger and impeller, press the lever against the right handgrip. To disengage, release the lever. 3 1 4 2 1 m-4034 Figure 14 1. Ignition switch 2. Choke 2 3. Throttle 4. Primer • Choke (Fig. 14)—Rotate the choke to the On position to start a cold engine.
• Recoil Starter (Fig. 17)—The recoil starter is on the back side of the engine. Pull the recoil starter to start the engine. 1 1 m 4947 934 Figure 19 Figure 17 1. Green ground wire clip 1. Recoil starter 7. Install the choke knob. Removing the Carburetor Heater Box 8. Insert the ignition key. If you operate the engine when the air temperature is above 40 F (4 C), remove the carburetor heater box (Fig. 18). Important Use the heater box as a reference for the choke and throttle positions. 9.
7. Cover the hole in the center of the primer (Fig. 14) with your thumb and slowly push in the primer 3 times, pausing a moment between pushes. 4. Shift the traction drive into the N (Neutral) position. 5. Stop the engine by doing one of the following: A. Move the throttle to the Slow position and remove the ignition key. 8. Grasp the recoil starter handle (Fig. 17) and pull it out slowly until positive engagement results; then pull the handle vigorously to start the engine. B.
3. Tighten the pivot bolt on the rear of the headlight assembly when the light is in the desired position. Note: To shift the wheels manually when the engine is not running, follow steps 1 and 2 and then lift up on the handles to unlock the wheels. Snowthrowing Tips Freewheeling or Self-propel Drive Danger You can operate the snowthrower with the self-propel feature engaged or disengaged (freewheeling). When you insert the axle pins through the outer axle holes and not through the wheel hubs (Fig.
• Do not overload the snowthrower by clearing snow at too fast a rate. If the engine slows down, shift the snowthrower into a lower gear to reduce the forward speed. • In wet or slushy conditions, maintain maximum engine speed, and do not overload the engine to prevent clogging the discharge chute. • If the front of the snowthrower tends to ride up, reduce the forward speed by shifting the snowthrower into a lower gear.
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 20. • Check the auger gearbox oil level and add oil if necessary. Refer to Checking the Auger Gearbox Oil Level on page 20. • Adjust the skids and the scraper.2 Refer to Adjusting the Skids and the Scraper on page 21.
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 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. 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 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. 31) 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. 31). 6 7 4 11. Install the traction drive belt on the idler pulley (Fig. 31). 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. 34). 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 12. 8. Wipe up any spilled oil. 9. Connect the wire to the spark plug.
Emptying the Fuel Tank Important Excessive chain tension may cause transmission damage. 1. Stop the engine and wait for all moving parts to stop. 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: 2. Disconnect the wire from the spark plug (Fig. 25). 3. Close the fuel shutoff valve (Fig. 15). A.
2. Touch up chipped surfaces with paint available from an Authorized Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting. Storage Warning 3. Tighten all screws and nuts. Repair or replace any damaged parts. Gasoline fumes are highly flammable, explosive, and dangerous if inhaled. If the product is stored in an area with an open flame, the gasoline fumes may ignite and cause an explosion. 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 19 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.
