Safety • Become familiar with the safe operation of the equipment, Improper use or maintenance can result in injury. To reduce the potential for injury, comply with these safety instructions, and pay attention to the safety-alert symbol , which means Caution, Warning, or Danger—personal safety instruction. Failure to comply with the instructions may result in personal injury or death.
Maintenance and Storage • Before leaving the operator’s position: – Stop on level ground. • Do not allow untrained personnel to service machine. – Disengage the parking brake (if provided). • Do not touch equipment or attachment parts which may be hot from operation. Allow all of the parts of the machine to cool before attempting to maintain, adjust, or service the machine. – Shut off the engine.
Aerator Safety Service The following list contains safety information specific to Toro products and other safety information you must know. • To ensure optimum performance and continued safety certification of the machine, use only genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous, and such use could void the product warranty. General Operation • Check carefully for overhead clearances (i.e.
Slope Indicator G011841 g011841 Figure 3 This page may be copied for personal use. 1. The maximum slope you can safely operate the machine on is 15 degrees. Use the slope chart to determine the degree of slope of hills before operating. Do not operate this machine on a slope greater than 15 degrees. Fold along the appropriate line to match the recommended slope. 2. Align this edge with a vertical surface, a tree, building, fence pole, etc. 3. Example of how to compare slope with folded edge.

Setup Media and Additional Parts Description Use Qty. Operator's Manual 1 Read before operating the machine. Key 2 Start the machine. DANGER 1 Charging or jump starting the battery may produce explosive gases. Battery gases can explode causing serious injury. Checking Tire Pressure • Keep sparks, flames, or cigarettes away from battery. No Parts Required • Ventilate when charging or using battery in an enclosed space.
1. Turn the key in the ignition switch to the OFF position and remove the key. 2. Measure the voltage of the battery with a voltmeter. 3. Use the table below to locate the charge state or the battery, and if needed, the battery-charger setting and charging interval recommended to charge the battery to 12.6 V or greater.
Tine-Pressure Control Product Overview The tine-pressure control is located on the left side of the control console (Figure 7). Use the tine-pressure control to adjust the downward pressure on the tines and core depth. Rotate the control counterclockwise to decrease the pressure and the length of the aeration plug; rotate clockwise to increase pressure and increase the length of the aeration plug. g020220 Figure 5 1. Platform 4. Engine controls 2. Parking-brake knob 5. Fuel cap 3.
Choke Lever On/Off Tine Ground Engagement Foot Switch The choke lever (Figure 7) is located on the control console (black lever). Located above the tine down pressure control on the control console. The choke lever is used to aid in starting a cold engine. To set the choke to the ON position, move the choke lever forward. To reduce the choke, move the choke lever backward. To enable the tines ground engagement, push down on the top of the switch.
Drive Wheel Release Valves Operation The drive wheel release valves are located on the left and right sides underneath the front of the unit. Note: Determine the left and right sides of the machine from the normal operating position. Note: During normal operating conditions, the washer on the lever is positioned inside the slots. Checking the Engine-Oil Level If you need to push the machine by hand, make sure that the valves are in the “released” position (Figure 10).
Adding Fuel Fuel tank capacity: 18.9 L (5 US Gallons) • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). • ETHANOL: Gasoline with up to 10% ethanol (gasohol) g025899 or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use.
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property. Fueling the Machine 1. Clean around the fuel-tank cap.
CAUTION Raising the machine for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the machine to fall, which could cause injury. Do not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support. 3. Turn the key in the ignition switch to the ON position, and move throttle level ahead to 1/2 throttle position.
Starting the Engine 2. While on level ground, block the wheels of the machine to prevent unintended movement. 1. Move the traction-control levers to the NEUTRAL position and engage the parking brake; refer to Traction-Control Levers (page 14)and Parking-Brake Handle (page 15). 3. Disengage the parking brake; refer to Parking-Brake Handle (page 15). 4.
Adjusting the Tine Down Pressure 4. Allow the engine to run for a minimum of 15 seconds, then turn the key in the ignition switch to the OFF position to shut off the engine; refer to Ignition Switch (page 15). Important: Keep the drive tires on the ground at all times. 5. Engage the parking brake; refer to Parking-Brake Handle (page 15). 4. Adjust the throttle for the working conditions; refer to Throttle Lever (page 14). 6.
g016673 Figure 19 To turn left or right, release pressure on the traction-control lever toward the desired turn direction. g016672 Figure 18 To make zero turns, lift your foot off of the tine-elevation switch to raise the tines. The head raises in 1 second. To turn left or right, pull the traction-control lever back toward neutral in the desired turn direction. The tines can be in the down position when making gradual turns. Important: Do not make a zero turn when the tines are in the down position.
4. Load the machine onto the trailer or truck. WARNING 5. Shut off the engine, remove the key, set the brake, and close the fuel valve. Loading the machine onto a trailer or truck increases the possibility of backward tip-over, and could cause serious injury or death. 6. Engage the parking brake and block the tires. 7. Use the tie-down points on the machine to securely bind the machine to the trailer or truck with straps, chains, cable, or ropes (Figure 20).
Maintenance WARNING WARNING While you are maintaining or adjusting the machine, someone could start the engine. Accidentally starting the engine could seriously injure you or other bystanders. The engine can become very hot. Touching a hot engine can cause severe burns. Allow the engine to cool completely before service or making repairs around the engine area. Remove the key from the ignition switch, engage parking brake, and pull the wire(s) off the spark plug(s) before you do any maintenance.
