Product Overview Operation Note: Determine the left and right sides of the machine from the normal operating position. Before Operation Before Operation Safety General Safety • Become familiar with the safe operation of the equipment, operator controls, and safety signs. • Check that all guards and safety devices, such as deflectors and/or grass catcher, are in place and working properly. • Always inspect the machine to ensure that the blades, blade bolts, and cutting assembly are not worn or damaged.
Filling the Fuel Tank – Store fuel in an approved container and keep it out of the reach of children. • Fuel is harmful or fatal if swallowed. Long-term DANGER exposure to vapors can cause serious injury and illness. Gasoline is extremely flammable and explosive. A fire or explosion from gasoline can burn you and others. – Avoid prolonged breathing of vapors. – Keep your hands and face away from the nozzle and the fuel-tank opening.
Checking the Engine-Oil Level Service Interval: Before each use or daily Important: If the oil level in the engine is too low or too high and you run the engine, you may damage the engine.
Adjusting the Cutting Height DANGER Adjusting the cutting-height levers could bring your hands into contact with a moving blade and result in serious injury. • Shut off the engine and wait for all movement to stop before adjusting the cutting height. • Do not put your fingers under the housing when adjusting the cutting height.
During Operation • Check the grass catcher components and the discharge chute frequently for any wear or deterioration and replace them with the manufacturer's recommended parts when necessary. During Operation Safety • Use accessories and attachments approved by General Safety The Toro® Company only. • Wear appropriate clothing, including eye protection; long pants; slip-resistant, substantial footwear; and hearing protection. Tie back long hair, secure loose clothing, and do not wear loose jewelry.
Starting the Engine 1. Connect the spark-plug wire to the spark plug. 2. Open the fuel valve (Figure 11). g024303 Figure 11 1. Fuel valve 3. Firmly push and hold the primer bulb in for 1 second (A of Figure 12). 4. Hold the blade-control bar in the Run/Shift position, about 5 cm (2 inches) below the handle (B of Figure 12). 5. Pull the starter handle lightly until you feel resistance, pull it sharply, then allow it to return slowly to the rope guide on the handle (C of Figure 12).
Shutting Off the Engine Release the blade-control bar. Both the engine and the blade should stop within 3 seconds. If they do not, contact an Authorized Service Dealer. Note: Close the fuel valve (Figure 11) if you will not be starting the engine soon afterward. Operating the Self-Propel Drive g024168 Figure 14 This machine has 3 ground speeds: 1 (slow), 2 (medium), and 3 (fast); it also has a Neutral (N) position. The self-propel-drive lever is located below and behind the fuel tank (Figure 13). 1.
Recycling the Clippings This machine comes from the factory ready to recycle grass and leaf clippings back into the lawn. To prepare the machine to recycle: • If the grass bag is on the machine, remove it (A of Figure 15). • If the rear-discharge plug is not installed, grip it by the handle, raise the rear deflector, and insert it into the rear-discharge chute until the latch locks into place (B of Figure 15).
Installing the Grass Bag 1. Shut off the engine and wait for all moving parts to stop. 2. Raise and hold up the rear deflector (A of Figure 16). 3. Remove the rear-discharge plug by pushing in the latch with your thumb and pulling the plug out from the machine (B and C of Figure 16). 4. Install the bag-rod ends into the notches at the base of the handle, and rock the bag back and forth to ensure that the bag-rod ends are seated at the bottom of both notches (D of Figure 16). 5.
Operating Tips grass at the 64 mm (2-1/2 inch), 76 mm (3 inch), or 89 mm (3-1/2 inch) cutting-height settings. Cut only about a third of the grass blade at a time. Do not cut below the 64 mm (2-1/2 inch) setting unless the grass is sparse or it is late fall when grass growth begins to slow down. General Tips • Review the safety instructions and read this • • • • • • • manual carefully before operating the machine.
• Use care when loading or unloading the machine. • Secure the machine from rolling. Note: The blade will draw in water and wash out the clippings. Let the water run until you no longer see clippings being washed out from under the machine. Cleaning under the Machine To ensure the best performance, keep the underside of the machine clean. Be especially careful to keep the kickers free of debris (Figure 17). 4. Shut off the engine and wait for all moving parts to stop. 5. Turn off the water. 6.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Change the engine oil. After the first 25 hours • Tighten any loose fasteners. Before each use or daily • • • • • Check the engine-oil level. Remove grass clippings and dirt from under the machine. Inspect the mower blades for wear or damage. Inspect the accelerator for wear or damage. Check the stopping time of the blade brake.
Servicing the Air Filter Changing the Engine Oil Service Interval: Every 25 hours—Clean the foam pre-filter (more frequently in dusty conditions). Service Interval: After the first 8 hours Every 50 hours Run the engine a few minutes before changing the oil to warm it. Warm oil flows better and carries more contaminants. Every 300 hours—Replace the paper air filter (more frequently in dusty conditions).
4. 5. 6. 15. Drain the gasoline from the fuel tank. Drain the engine oil; refer to Changing the Engine Oil (page 22). Place a rag under the oil filter (Figure 20) to catch any oil that may leak out as you remove the oil filter. Recycle the used oil filter properly. Servicing the Spark Plug Service Interval: Every 100 hours—Inspect, clean, and adjust the spark plug gap; replace the spark plug if necessary. Use an NGK BPR5ES spark plug or equivalent. 1.
Maintaining the Blade Adjusting the Self-Propel Drive Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades. If the machine is new, does not self-propel, or it tends to creep forward, adjust the drive cable. 1. Move the machine outside and onto a paved surface near a solid wall to safely prevent the machine from moving forward while the engine is running. 2. Position the machine with the front tires against the wall.
Inspecting the Blade Service Interval: Before each use or daily—Inspect the mower blades for wear or damage. Carefully examine the blade for sharpness and wear, especially where the flat and the curved parts meet (Figure 25A). Because sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the machine. If you notice a slot or wear (Figure 25B and Figure 25C), replace the blade; refer to Removing the Blade (page 25).
Balancing the Blade 1. Check the balance of the blade by placing the center hole of the blade over a nail or screwdriver shank clamped horizontally in a vise (Figure 28). g033871 g002280 Figure 29 Figure 28 1. Handle bar 2. Cable-anchor nut Note: You can also check the balance using a commercially manufactured blade balancer. 2. If either end of the blade rotates downward, file that end (not the cutting edge or the end near the cutting edge) until neither end of the blade drops.
4. Lift off the cover and brush out all the debris around the belt area. Storage 5. Install the belt cover. 6. Connect the wire to the spark plug. To prepare the machine for off-season storage, perform the recommended maintenance procedures; refer to Maintenance (page 21). Cleaning the Wheels Store the machine in a cool, clean, dry place. Cover the machine to keep it clean and protected. Service Interval: Every 40 hours 1.
8. Tighten all nuts, bolts, and screws. 9. Touch up all rusted or chipped paint surfaces with paint available from an Authorized Service Dealer. Removing the Machine from Storage 1. Check and tighten all fasteners. 2. Remove the spark plug and spin the engine rapidly using the starter to blow out the excess oil from the cylinder. 3. Clean the spark plug or replace it if it is cracked, broken, or if the electrodes are worn. 4. Install the spark plug; refer to Servicing the Spark Plug (page 23).
Troubleshooting Problem The engine does not start. The engine starts hard or loses power. Possible Cause 1. The fuel tank is empty or the fuel system contains stale fuel. 1. Drain and/or fill the fuel tank with fresh fuel. If the problem persists, contact an Authorized Service Dealer. 2. The throttle lever is not in the CHOKE position. 3. The wire is not connected to the spark plug. 4. The spark plug is pitted, fouled, or the gap is incorrect. 2. Move the throttle lever to the CHOKE position. 3.
