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. Figure 9 1. Side discharge chute 2.
Filling the Fuel Tank with Gasoline 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. You may use leaded gasoline if unleaded gasoline is not available. Important: Do not add oil to the 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. • Always place gasoline containers on the ground and away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge. Figure 12 1. Oil fill/dipstick 2.
4. Pull the recoil starter (Figure 17) or (Figure 18). Figure 17 Model 22193 Figure 14 3. Hold the blade control bar against the handle (Figure 15) or (Figure 16). Figure 18 Model 22194 5. If the mower does not start in 1 or 2 pulls, press the primer button 1 or 2 times and try starting it again. Note: If the mower still does not start, contact an Authorized Service Dealer. Stopping the Engine Figure 15 Model 22193 Release the blade control bar (Figure 19).
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. Using the Self-propel Drive Model 22194 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 20).
Figure 24 Figure 22 2. Lift open the side discharge door (Figure 25). 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. Figure 25 Important: Ensure that the rear discharge plug is in place before you recycle the clippings (Figure 23). 3. Install the side discharge chute and close the door onto the chute (Figure 26).
Operating Tips 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. 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.
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 28). 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 13). 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 13). 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 34). Figure 32 Figure 34 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.
