Safety • Never let children or untrained people operate or service the equipment. Local regulations may restrict the age of the operator. This lawn mower meets or exceeds the CPSC blade safety requirements for walk-behind rotary lawn mowers and the B71.4 specifications of the American National Standards Institute in effect at the time of production. • The owner/user can prevent and is responsible for accidents or injuries occurring to themselves, other people, or property.
Safety and Instructional Decals including emptying the catcher or unclogging the chute. • Stop equipment and inspect blade after striking objects or if an abnormal vibration occurs. Make necessary repairs before resuming operations. Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost. • Keep hands and feet away from the cutting units.

No parts required – Fill the crankcase with oil. No parts required – Adjust the handle height.
Important: If the handle has round holes, the square shank of the bolts will not fit into the holes in the handle at this time. 1. Remove the fastener that attaches the handle braces to the lower handle ends. 2. Insert the bolt through the hole in each of the handle braces that sets the handle to the desired position and tighten (Figure 4). 6.

Operation Note: Determine the left and right sides of the machine from the normal operating position. Each time before you mow, make sure that the self-propel drive and the blade control bar operate properly. When you release the blade control bar, the blade and self-propel drive should stop. If they do not, contact an Authorized Service Dealer. This machine produces sound levels in excess of 85dBA at the operator’s ear and can cause hearing loss through extended periods of exposure. Figure 9 1.
Filling the Fuel Tank with Gasoline 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. For best results, use clean, fresh, lead-free gasoline with an octane rating of 87 or higher. To ensure freshness, purchase only the quantity of gasoline that you expect to use in 30 days. Using unleaded gasoline results in fewer combustion deposits and longer engine life.
Figure 10 1. Oil fill/dipstick 2. Fuel tank cap 3. Air cleaner 2. Remove the cap from the tank. 3. Fill the fuel tank with unleaded gasoline to within 1/4 to 1/2 inch (6 to 13 mm) from the top of the tank. Do not fill into the filler neck. Important: Do not fill the tank more than 1/4 inch (6 mm) from the top of the tank because the gasoline must have room to expand. Figure 12 3. Hold the blade control bar against the handle (Figure 13) or (Figure 14). 4.
Important: When you release the blade control bar, both the engine and blade should stop within 3 seconds. If they do not stop properly, stop using your mower immediately and contact an Authorized Service Dealer. 4. Pull the recoil starter (Figure 15) or (Figure 16). Using the Self-propel Drive Model 22164 only To operate the self-propel drive, simply walk with your hands on the upper handle and your elbows at your sides, and the mower will automatically keep pace with you (Figure 18).
Figure 20 Side-discharging the Clippings Use the side discharge for cutting very tall grass. If the bag is on the mower, remove it and insert the rear discharge plug (refer to Removing the Grass Bag) before side-discharging the clippings. Important: Ensure that the rear discharge plug is in place before you recycle the clippings (Figure 21). Figure 19 Figure 21 Recycling the Clippings Your mower comes from the factory ready to recycle the grass and leaf clippings back into the lawn.
Operating Tips General Tips • Maintain a sharp blade throughout the cutting season. Periodically file down nicks on the blade. • Replace the blade when necessary with an original Toro replacement blade. • Mow only dry grass or leaves. Wet grass and leaves tend to clump on the yard and can cause the mower to plug or the engine to stall. Figure 22 2. Lift open the side discharge door (Figure 23). Wet grass or leaves can cause serious injury if you slip and contact the blade. Mow only in dry conditions.
slower; then mow again at a lower setting for the best lawn appearance. If the grass is too long and the leaves clump on top of the lawn, the mower may plug and cause the engine to stall. • Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization. If the finished lawn appearance is unsatisfactory, try one or more of the following: • Sharpen the blade. • Walk at a slower pace while mowing. • Raise the cutting height on your mower. • Cut the grass more frequently.
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 8 hours • Change the engine oil. Before each use or daily • Check the engine oil level. • Inspect the mower blades for wear or damage. • Clean under the mower housing. Every 25 hours • Lubricate the rear wheel gears. • Clean the foam pre-cleaner (more frequently in dusty conditions).
Lubrication Engine Maintenance Lubricating the Wheel Gears Servicing the Air Filter Service Interval: Every 25 hours Service Interval: Every 25 hours Every 300 hours Lubricate each rear wheel with grease yearly. 1. Wipe the grease fittings just inside the rear wheels with a clean rag (Figure 26). Clean the foam pre-cleaner every 25 operating hours. Replace the paper air filter once every season or every 300 operating hours; replace it more frequently in dusty conditions.
Note: Install a new paper air filter if you discarded the old one. 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug (Figure 11). 9. Install the cover and secure it with the screw. 3. Clean around the spark plug. 4. Remove the spark plug from the cylinder head. Changing the Engine Oil Important: Replace a cracked, fouled, or dirty spark plug. Do not clean the electrodes because grit entering the cylinder can damage the engine.
Fuel System Maintenance Blade Maintenance Emptying the Fuel Tank and Cleaning the Fuel Filter Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades. Maintaining the Cutting Blade 1. Stop the engine and wait for all moving parts to stop. Service Interval: Yearly 2. Disconnect the wire from the spark plug (Figure 11). The fuel filter (screen) element is located inside the fuel tank. Clean the fuel filter element yearly. 3.
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 32). Figure 30 Figure 32 3. Wear 4. Slot formed 1. Sail 2. Flat part of the blade Note: You can also check the balance using a commercially manufactured blade balancer. Note: For the best performance, install a new blade before the cutting season begins. During the year, file down any small nicks to maintain the cutting edge. 2.
Cleaning Tipping the mower may cause the fuel to leak from the carburetor or the fuel tank. Gasoline is extremely flammable, highly explosive, and, under certain conditions, can cause personal injury or property damage. Cleaning under the Mower Housing To ensure the best performance, keep the underside of the mower housing clean. Avoid fuel spills by running the engine dry or by removing the gasoline with a hand pump; never siphon. Washing Method Service Interval: Before each use or daily 3.
Storage 2. Clean any dirt and chaff from the cylinder, cylinder head fins, and blower housing. To prepare the mower for off-season storage, perform the recommended maintenance procedures. Refer to Maintenance. 3. Remove grass clippings, dirt, and grime from the external parts of the engine, the shrouding, and the top of the mower housing. Store the mower in a cool, clean, dry place. Cover the mower to keep it clean and protected. 4. Check the condition of the blade.
Troubleshooting Problem Engine does not start 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 gasoline. If the problem persists, contact an Authorized Service Dealer. 2. The wire is not connected to the spark plug. 3. The spark plug is pitted, fouled, or the gap is incorrect. 2. Connect the wire to the spark plug. 1. Drain and fill the fuel tank with fresh gasoline. 2.
