This lawn mower is capable of amputating hands and feet and of throwing objects. Failure to observe the following safety instructions could result in serious injury or death. This manual identifies potential hazards and has special safety messages that help you and others avoid personal injury and even death. Danger, Warning, and Caution are signal words used to identify the level of hazard. However, regardless of the hazard, be extremely careful.
– Refuel outdoors only and do not smoke while refuelling. • Disengage all blade and drive clutches before starting the engine. – Add fuel before starting the engine. Never remove the cap of the fuel tank or add gasoline while the engine is running or when the engine is hot. • Start the engine carefully according to instructions and with feet well away from the blade(s). • Do not tilt the lawn mower when starting the engine, unless you must tilt the lawn mower to start it.
• Do not mow on wet grass. Reduced footing could cause slipping. Maintenance and Storage • Grass catcher components are subject to wear, damage, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check the components and replace them with the manufacturer’s recommended parts when necessary. • Keep all nuts, bolts (especially blade attachment bolts), and screws tight to ensure that the lawn mower is in safe working condition.

Installing the Battery 1 2 Electric-start Model only 1. Charge the battery. Refer to Charging the Battery on page 20. 1626 2. Align the pins in the battery case with the holes in the battery bar, and lower the pins into the holes until the battery case snaps into place (Fig. 5). 1 Figure 6 1. Oil fill cap 2. Dipstick To add oil: 2 1. Move the lawn mower to a level surface. 2. Clean around the dipstick (Fig. 6). 3 3. Remove the dipstick by rotating the cap counterclockwise and pulling it out.
Important Do not use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, premium gasoline, or white gas. Using these fuels can damage the engine’s fuel system. Important days old. 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.
Reviewing the Maintenance Schedule Note: Do not use the primer to start a warm engine after a brief shutdown. However, cool weather may require you to prime the engine again. Review the Recommended Maintenance Schedule on page 14. You may need to perform one or more additional procedures before or soon after you begin operating the lawn mower. 3. Hold the blade control bail against the upper handle (Fig. 10).
2. Move the lawn mower into the grass; stop moving the lawn mower when the SmartWheel design on one of the rear wheels is upright (Fig. 13). 3. Use the SmartWheel design to compare the tips of the grass blades to the letters on the wheel. The letter on the SmartWheel that matches the tips of the grass blades is the proper cutting height. m–4206 Figure 12 4. Press down on the red button and hold the cutting height adjustment handle to move the cutting height up or down (Fig. 14).
Using the Grass Bag Danger Occasionally, you may want to use the grass bag for bagging lush grass or collecting leaves. If the rear door does not close completely, the lawn mower could throw objects, causing serious personal injury or death. Installing the Grass Bag If you cannot close the rear door because the grass clippings clog the discharge area, stop the engine, wait for all moving parts to stop, and remove the grass clippings (with a stick, not your hand) until the rear door closes completely.
Danger Warning If the rear door does not close completely, the lawn mower could throw objects, causing serious personal injury or death. Operating a lawn mower with its engine running at a speed greater than the factory setting can cause the lawn mower to throw a part of the blade or engine into the operator’s or bystander’s area and result in serious personal injury or death.
• For light leaf coverage, set all the wheels at the same cutting height setting. • Slow down your mowing speed if the lawn mower does not cut the leaves finely enough. • If there are more than 5 inches (12.7 cm) of leaves on the lawn, set the front cutting height one or 2 notches higher than the rear cutting height. This makes it easier to feed the leaves under the lawn mower deck. • If you mow over oak leaves, you can add lime to the grass in the spring to reduce the acidity of the oak leaves.
Caution If you leave the wire on the spark plug, someone could accidently start the engine and seriously injure you or other bystanders. Disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Checking the Engine Oil Level Before you use the lawn mower, ensure that the oil level is between the Add and the Full marks as shown on the dipstick (Fig. 6). If the oil level is below the Add mark, add oil.
Servicing the Air Filter Warning Clean the pre-cleaner and replace the air filter once every season or every 25 operating hours; replace it more frequently in dusty operating conditions. A broken or missing washout fitting could expose you and others to thrown objects or to the blade, causing injury or death. Important Do not operate the engine without the air filter element; extreme engine damage will occur. • Replace a broken or missing washout fitting immediately before using the lawn mower again.
Important Replace a cracked, fouled, or dirty spark plug. Do not clean the electrodes because grit entering the cylinder could damage the engine. 4. Set the gap on the new plug to 0.020 in. (0.50 mm) (Fig. 21). 1 m 4785 1 Figure 23 1. Belt guide tab 986 Figure 21 1. 0.020 in. (0.50 mm) 6. Pull the cable jacket down (toward the lawn mower) to remove all the slack in the cable (Fig. 22). 5. Install the spark plug and the gasket seal. 7.
Draining the Oil above the Lawn Mower Deck (Preferred Method) 4. Place a drain pan under the lawn mower. 5. Remove the oil drain plug, return the lawn mower to its operating position, and allow the oil to drain into the drain pan (Fig 26). 1. Remove the grass bag. 2. Disconnect the wire from the spark plug (Fig. 9). Note: Avoid spilling the oil on the belt. 3. Drain the gasoline from the fuel tank; refer to steps 3 and 4 of Emptying the Fuel Tank on page 20.
1 Warning A Tipping the lawn 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. 2 1 B 3 Avoid fuel spills by running the engine dry or removing gasoline with a hand pump; never siphon. 1 C 4 3. Drain the gasoline from the fuel tank; refer to steps 3 and 4 of Emptying the Fuel Tank on page 20. 270 Figure 28 1. Sail 2. Flat part of blade 4.
Note: Turn the blade bolt counterclockwise to loosen it. 2. Lift off the cover and brush out all the debris from the belt area. Sharpening the Blade 3. Install the belt cover. File the top side of the blade to maintain its original cutting angle (Fig. 29A) and inner cutting edge radius (Fig. 29B). The blade will remain balanced if you remove the same amount of material from both cutting edges.
Folding the Handle Note: You do not need to remove the battery if the lawn mower is near an electrical outlet. 4. Connect the Toro electro charger to the battery and plug it into a 230V AC power outlet. Warning Important Use only the Toro electro charger; other chargers could damage the battery. Always charge the battery indoors and at room temperature (70 F) when possible. Do not charge the battery longer than 72 hours; overcharging can damage the battery.
Removing From Storage 1. Run the lawn mower until the engine stops from running out of fuel. 2. Prime the engine and start it again. Warning 3. Allow the engine to run until it stops. When you can no longer start the engine, it is sufficiently dry. Folding or unfolding the handle improperly can pinch, stretch, or damage one or more of the cables. Any pinched, stretched, or damaged cable may cause an operational failure that results in an unsafe operating condition. Preparing the Engine 1.
