Engine Maintenance Engine Safety Shut off the engine before checking the oil or adding oil to the crankcase. Servicing the Air Cleaner Service Interval: Before each use or daily—Clean and check the air-cleaner foam and paper elements. g037326 Figure 17 Every 50 hours—Replace the air-cleaner foam and paper elements. 1. Foam element 2. Paper element Note: Service the air cleaner more frequently if the 3. Nuts operating conditions are extremely dusty or sandy. Removing the Foam and Paper Elements 5.
Installing the Foam and Paper Elements 1. Important: To prevent engine damage, always operate the engine with the complete foam and paper-air cleaner assembly installed. 1. Install the foam filter onto the paper filter (Figure 17). 2. Install the foam and paper filter into the air-cleaner housing. 3. Secure the filter assembly to the housing using the 2 nuts (Figure 17). 4. Install the air-cleaner cover and tighten the 2 knobs (Figure 16). 2.
2. Drain the oil from the engine (Figure 20). g027477 Figure 21 g029369 Figure 20 3. Remove the engine-oil filter (Figure 21). After the oil is drained, install a new oil filter. Note: Ensure that the new oil-filter gasket touches the engine, and then tighten the filter an extra 3/4 turn. 18 4. Slowly pour approximately 80% of the specified amount of oil into the fill hole (Figure 22). 5. Allow 3 to 5 minutes for the oil to settle, then check the oil level (Figure 22).
Removing the Spark Plug 1. Park the machine on a level surface, shut off the engine, and remove the key from the ignition switch. 2. Before removing the spark plug(s), clean the area around the base of the plug to keep dirt and debris out of the engine. 3. Remove the spark plug (Figure 23). g027478 Figure 23 Checking the Spark Plug g027484 Figure 22 6. Important: Do not clean the spark plug(s).
Installing the Spark Plug Fuel System Maintenance Tighten the spark plug to 20 N∙m (15 ft-lb). DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you, others, and can damage property. • Perform any fuel-related maintenance when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills. • Never smoke when draining gasoline and stay away from an open flame or where a spark may ignite the gasoline fumes.
Electrical System Maintenance Electrical System Safety • Disconnect the battery before repairing the machine. Disconnect the negative terminal first and the positive last. Connect the positive terminal first and the negative last. g186943 • Charge the battery in an open, well-ventilated area, away from sparks and flames. Unplug the charger before connecting or disconnecting the battery. • Wear protective clothing and use insulated tools.
4. Charging the Battery Remove the nuts and securing rods from both sides of the battery, battery cover, and battery tray. Service Interval: Before storage—Charge the battery and disconnect battery cables. 1. Remove the battery from the chassis; refer to Removing the Battery (page 21). 2. Charge the battery for a minimum of 1 hour at 6 to 10 amps. Note: Do not overcharge the battery. 3.
Servicing a Replacement Battery Drive System Maintenance The original battery is maintenance-free and does not require service. For servicing a replacement battery, refer to the battery manufacturer’s instructions. Checking the Tire Pressure Service Interval: Before each use or daily Every 25 hours—Check tire pressure. Maintain the air pressure in the tires as specified. Check the pressure at the valve stem (Figure 29). Check the tires when they are cold to get the most accurate pressure reading.
Cooling System Maintenance Belt Maintenance Cleaning the Engine Screen Service Interval: Every 25 hours—Check the belts for wear/cracks. Inspecting the Belts Service Interval: Before each use or daily—Clean the engine air-intake screen. Check the belts for cracks, frayed edges, burn marks, or any other damage. Replace damaged belts. To ensure proper cooling, ensure that the air-intake screen, cooling fins, and other external surfaces of the engine are kept clean at all times.
Replacing the Mower Belt 1. Park the machine on a level surface, disengage the blade, and engage the parking brake. 2. Turn the ignition key to the OFF position, remove the key, and disconnect the spark plug wire from the spark plug. 3. Use lifting equipment to raise the machine and support it with jack stands. 4. Remove the transmission belt; refer to Replacing the Transmission Belt (page 24). 5.
Mower Maintenance Checking for a Bent Blade To ensure a superior quality of cut, keep the blade sharp. For convenient sharpening and replacement, you may want to keep extra blades on hand. Straight Blade Only WARNING A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. Blade Safety A worn or damaged blade can break, and a piece of the blade could be thrown at you or bystanders, resulting in serious personal injury or death.
Removing the Blade Straight Blade Only Replace the blade if it hits a solid object, if the blade is out of balance, or if a blade is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine Toro replacement blades. Replacement blades made by other manufacturers may result in nonconformance with safety standards. 1. Hold the blade end using a rag or thickly-padded glove. 2. Remove the blade bolt, curved washer, and blade from the spindle cup assembly (Figure 37).
2. For straight blades only, check the balance of the blade by putting it on a blade balancer (Figure 39). Cleaning If the blade is not balanced, file some metal off the back side of the blade (opposite of the cutting edge) only (Figure 36). Removing Debris from the Machine Repeat this procedure until the blade is balanced. Regular cleaning and washing increases the lifespan of the machine. Clean the machine directly after use. Note: If the blade stays in a horizontal position, the blade is balanced.
Storage 15. Paint all scratched or bare metal surfaces. Paint is available from your Authorized Service Dealer. Storing the Machine 16. Store the machine in a clean, dry garage or storage area. For storage over 30 days, prepare the machine as follows: 17. Cover the machine to protect it and keep it clean. 1. Park the machine on a level surface, disengage the blade, and engage the parking brake. 2.
Troubleshooting Problem The engine overheats. Possible Cause 1. The engine load is excessive. 1. Reduce the ground speed. 2. The oil level in the crankcase is low. 3. The cooling fins and air passages under the engine blower housing are plugged. 4. The air cleaner is dirty. 2. Add oil to the crankcase. 3. Remove the obstruction from the cooling fins and air passages. 5. Dirt, water, or stale fuel is in fuel system. The starter does not crank.
Problem The cutting height is uneven. The blade does not rotate. The brush cutter does not move when the traction drive is engaged. The cutting performance is poor. Possible Cause Corrective Action 1. The blade(s) is not sharp. 1. Sharpen the blade(s). 2. The cutting blade is bent. 3. The underside of the mower is dirty. 4. A blade spindle is bent. 2. Install a new cutting blade. 3. Clean the underside of the mower. 4. Contact an Authorized Service Dealer. 1. The mower belt is off the pulley. 1.
