Wheel-Clutch Levers Speed-Selector Lever The wheel-clutch levers are located below the right and left handles. The speed-selection lever is located on the main console panel (Figure 6). The wheel clutch levers allow the drive to momentarily disengage to 1 or both wheels with the traction-drive lever squeezed. This allows for easier turning and maneuvering the machine (Figure 6). The speed selector has 6 forward and 2 reverse settings.
Operation DANGER When fueling, under certain circumstances, a static charge can develop, igniting the gasoline. A fire or explosion from gasoline can burn you and others and damage property. Fueling the Machine Fuel tank capacity: 4.1 L (1.0 US gallon) • For best results, use only clean, fresh (less than 30 days • Always place gasoline containers on the ground and away from your vehicle before filling. old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
Opening the Fuel-Shutoff Valve Operating the Engine Move the fuel-shutoff valve located below the choke, to the right to turn on fuel (Figure 9). Positioning the Air-Cleaner Cover for Cold or Warm Air Temperature Important: Running the engine with the air-cleaner cover positioned for cold-weather operation in normal conditions can damage the engine.
3. Place the throttle midway between the SLOW and FAST positions located on rear, right side of the engine (Figure 10). 4. Slowly pull the engine-recoil handle until you feel resistance and then stop (Figure 10). Note: Allow the recoil handle to return and then sharply pull it straight out. g001012 Note: Allow the rope to return slowly. Figure 11 5. Allow the engine to warm up for several minutes, then move the choke toward the OFF position (Figure 9).
Operating the Broom DANGER When the machine is in operation, contact with rotating or moving parts will severely injure hands and feet. • Before adjusting, cleaning, inspecting, troubleshooting, or repairing the machine, stop the engine and wait for all moving parts to stop. Disconnect the wire from the spark plug and keep it away from the plug to prevent someone from accidentally starting the engine. • Stay behind the handles and away from the broom while operating the machine.
2. Place the speed selector lever into the desired position and slowly squeeze the left hand traction drive lever. Important: Make sure that the traction drive is engaged before operating the broom; otherwise, the broom may drive the machine in the reverse direction. 3. To engage the broom, slowly squeeze the right broom lever to the handle (Figure 15). g017922 Figure 16 1. 51 to 102 mm (2 to 4 inches) maximum width g001013 Figure 15 3. Swept area 2.
Using the Alternate Caster Location 6. Raise or lower the caster wheel tube to achieve the sweep area as stated in Checking the Sweeping Path (page 15). When working in snow, mount the casters behind the broom bristles (Figure 18). Note: Select any hole combination that is in alignment to place and latch the retaining pin; match the same position on the other side. 7.
Preventing Freeze-up • In snowy and cold conditions, some controls and moving parts may freeze. Do not use excessive force when trying to operate frozen controls. If you have difficulty operating any control or part, start the engine and let it run for a few minutes. • After using the machine, let the engine run for a few minutes to prevent moving parts from freezing. Engage the broom to clear any remaining snow from inside the housing.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 2 hours • Check the traction cable. • Check the broom cable. After the first 5 hours • Change the engine oil. Before each use or daily • Check the engine oil level. • Check the broom-shaft shear pin. • Check for loose hardware.
Preparing for Maintenance 2. Remove the belt cover and the engine shield. 1. Move the machine to a level surface. 3. Move the speed-selector lever to the R2 position. 2. Shut off the engine and allow it to cool. 4. Dip a long, clean, small-tipped paint brush in automotive engine oil and lightly lubricate the hex shaft (Figure 21). 3. Disconnect the spark-plug wire from the spark plug and keep the wire away from the plug, to prevent accidental starting (Figure 19).

Installing the Traction Belt Maintaining the Chassis 1. Align the traction belt between the friction wheel and the traction pulley (Figure 43). Checking for Loose Hardware 2. Align the belt into the groove at the bottom of the traction pulley (Figure 42). Service Interval: Before each use or daily 1. Visually inspect the machine for any loose missing hardware or any other possible problem. 3. Pull the tension pulley outward (Figure 42). 4.
Storage 15. Clean the machine thoroughly. 16. Touch up chipped surfaces with paint available from an Authorized Toro Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting. WARNING Gasoline fumes are highly flammable, explosive, and dangerous if inhaled. If you store the machine in an area with an open flame, the gasoline fumes may ignite and cause an explosion.
Troubleshooting Problem The engine does not start, starts hard, or fails to keep running. Possible Cause 1. The fuel tank is empty. 1. Fill the fuel tank. 2. The fuel-shutoff valve is closed. 3. The throttle and choke are not in the correct position. 2. Open the fuel-shutoff valve. 3. Be sure the throttle control is midway between the Slow and Fast positions, and the choke is in the On position for a cold engine or the Off position for a warm engine. 4. Clean the fuel-valve screen and cup. 5.
Problem Possible Cause Corrective Action The broom wears out prematurely. 1. You are using the incorrect broom height. 1. Adjust the broom height. The speed selector is difficult to move or frozen in place. 1. The hex shaft needs lubrication. 1. Lubricate the hex shaft.
