• Disengage all clutches and shift into neutral before starting the engine. WARNING signals a hazard that may cause serious injury or death if you do not follow the recommended precautions. • Do not operate the equipment without wearing adequate winter garments. Wear footwear which will improve footing on slippery surfaces. CAUTION signals a hazard that may cause minor or moderate injury if you do not follow the recommended precautions. • Handle fuel with care; it is highly flammable.
• Run the machine a few minutes after throwing snow to prevent freeze-up of the collector/impeller (auger/impeller). (With the engine running, pull the recoil starter handle several times.) spark-plug wire, and keep the wire away from the plug to prevent someone from accidentally starting the engine. Disconnect the cable on electric motors. • Do not run the engine indoors, except when starting it and for moving the snowthrower in or out of the building. Open the outside doors; exhaust fumes are dangerous.
• When storing the snowthrower for more than 30 days, drain the gasoline from the fuel tank to prevent a potential hazard. Store gasoline in a safety approved, red metal container. Remove the key from the ignition switch before storing the snowthrower. • To ensure the best performance and safety, purchase only genuine Toro replacement parts and accessories to keep the Toro all Toro. Do not use “Will Fit” replacement parts and accessories as they could cause a safety hazard.
Safety and Instruction Decals Safety and instruction decals are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.

Note: If the force does not noticeably increase, remove Installing the Auger/Impeller Drive Control Linkage the belt cover (refer to Replacing the Auger/Impeller Drive Belt, steps 1 and 2 on page 19) and measure two inches (5.1 cm) above the handgrip at the point where you remove the slack from the auger/impeller drive belt. 1. Loosen the jam nut above the clevis on the upper control rod (Fig. 8). 5. To adjust the distance: 2.
Checking the Tire Pressure Check the pressure of the tires because they are overinflated at the factory for shipping. Reduce the pressure equally in both tires to between 7–15 psi (48–103 kPa). 658 Before Starting Figure 11 1. Worm gear and bracket 2. Bolt, pyramidal washer, and locknut 3. Mounting flange Filling the Engine with Oil The engine comes from the factory with only a few ounces of oil in the crankcase. Before starting the engine, add oil. The crankcase holds 21 ounces (0.
Note: To ensure an accurate oil level reading, you must fully install the dipstick. DANGER 7. Remove the dipstick. POTENTIAL HAZARD • In certain conditions gasoline is extremely flammable and highly explosive. 8. Read the oil level on the dipstick. 9. If the oil level is below the Full mark, slowly add oil, checking the level frequently (steps 5 through 8), until the dipstick reads Full. WHAT CAN HAPPEN • A fire or explosion from gasoline can burn you, others, and cause property damage.
Use a fuel stabilizer/conditioner regularly during operation and storage. A stabilizer/conditioner cleans the engine during operation and prevents gum–like varnish deposits from forming in the engine during storage. 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. 1. Clean the area around the fuel tank cap (Fig. 13). 2. Remove the cap from the fuel tank. 3.

IMPORTANT: Check the auger and impeller to 7. After the engine starts, immediately rotate the choke (Fig. 15) to the 3/4 position. ensure that both parts are not frozen but free to rotate. Also, ensure that the discharge chute is not obstructed. Use a stick, not your hand, to remove an obstruction from the discharge chute. 8. As the engine warms up, rotate the choke to the 1/2 position; then to the Off position.
Snowthrowing Tips happens, reduce forward speed by shifting into a lower gear. If the front still tends to ride up, lift up on both handles to hold down the front of snowthrower. DANGER • Discharge the snow downwind whenever possible. • Overlap each swath to ensure complete snow removal. POTENTIAL HAZARD • When the snowthrower is in operation, the impeller and auger can be rotating. • If the wheels slip, shift into a lower gear to reduce forward speed.

CAUTION POTENTIAL HAZARD • If you leave the wire on the spark plug, someone could start the engine. WHAT CAN HAPPEN • Someone accidentally starting the engine could seriously injure you or other bystanders. HOW TO AVOID THE HAZARD • Pull the wire off of the spark plug before you do any maintenance. Also, push it aside so it does not accidentally contact the spark plug. Checking the Engine Oil Level 2. Block up the rear of the snowthrower chassis. 3. Remove the left wheel.
4. Remove the auger/impeller drive belt from the engine pulley and the large auger/impeller pulley (Fig. 22). 5. Tip the snowthrower forward and block it so it cannot fall. 6.

The grease must be visible through the opening.
Replacing the Auger/Impeller Drive Belt 17. Install the auger/impeller drive belt around the large auger/impeller pulley and engine pulley, ensuring that the belt is on the inside of the idler pulley and belt guide (Fig. 22). When the auger/impeller drive belt (Fig. 21) becomes worn, stretched, oil–soaked, or otherwise damaged, replace the belt. You can obtain a new belt from your Authorized Service Dealer. 18. Adjust the belt guide so that there is 1/8 in. (0.

3. Slide the skids down as far as possible to support the auger as far from the level surface as the skid adjustment allows. 4. Tighten the four flange nuts. Adjusting the Speed Selector If the snowthrower is slow, the No.1 speed selection has no speed, or the speed selector does not move into the No. 3 speed selection, adjust the speed selector linkage. 1. Pull the wire off of the spark plug and ensure that the wire does not contact the spark plug. 2.
2. Pull the wire off of the spark plug (Fig. 29) and remove the plug from the cylinder head. m–2592 Figure 27 724 Figure 29 1. Screws 1. Spark plug wire 5. Lightly lubricate the snowthrower with light oil as shown in Figure 28 IMPORTANT: Replace a cracked, fouled or dirty spark plug. Do not sand blast, scrape or clean electrodes because grit may release from the plug and fall into the cylinder and cause engine damage.
10. Pull the recoil starter slowly to distribute oil on the inside of the cylinder. WARNING 11. Change the engine oil. Refer to Changing the Engine Oil on page 17. POTENTIAL HAZARD • Gasoline is highly flammable. WHAT CAN HAPPEN • Gasoline can be ignited and cause serious personal injury. Preparing the Snowthrower 12. Lubricate the snowthrower. Refer to Lubricating the Snowthrower on page 21. HOW TO AVOID THE HAZARD • Drain gasoline outdoors. • Drain gasoline from a cold engine only.
