Operation • Let the engine cool before storing and do not store near flame. • Never run an engine in an enclosed area. • Only operate in good light, keeping away from holes and • Shut off the fuel while storing or transporting on trailers. Do not store fuel near flames or drain indoors. hidden hazards. • Park the aerator on level, hard ground. Never allow • Be sure all drives are in neutral before starting engine.
Slope Indicator G011841 Figure 3 This page may be copied for personal use. 1. The maximum slope you can safely operate the machine on is 20 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 20 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.
Safety and Instructional Decals 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. 119-0217 1. Warning—stop the engine; stay away from moving parts; keep all guards and shields in place. 121-6150 1.

Tine Control Lever Operation The tine control lever lifts the rear wheels, causing the rear of the machine to be supported on the aerating tines. Push the tine control lever down to lift the wheels and drop the tines. Pull it up to lower the wheels and raise the tines out of the ground. Note: Determine the left and right sides of the machine from the normal operating position. Checking the Engine Oil Level Service Interval: Before each use or daily The engine crankcase can hold 20 ounces (0.
Filling the Fuel Tank with Gasoline • Oxygenated fuel with up to 10% ethanol or 15% MTBE by volume is acceptable. • Do Not use ethanol blends of gasoline (such as E15 Fuel tank capacity: 1 US Gallon (3.8 l) or E85) with more than 10% ethanol by volume. Performance problems and/or engine damage may result which may not be covered under warranty. DANGER • Do Not use gasoline containing methanol. In certain conditions, gasoline is extremely flammable and highly explosive.
Stopping the Engine 1. Release the traction control lever and allow it to return to neutral. 2. Move the throttle lever all the way rearward to stop the engine. 1 Driving the Machine 2 • To move forward, press the control lever forward • (Figure 11). The further forward you push it, the faster the machine will travel. To move in reverse, pull the control lever rearward (Figure 11). The further forward you pull it, the faster the machine will travel.
Note: If your machine is moving too slowly and not properly aerating, see Adjusting the Machine Ground Speed (page 20) Aerating 1. Drive the machine to the desired location and stop it. 2. Push the tine control lever down and forward to raise the rear wheels and engage the tines. 1 g017584 Figure 13 1. Weight 2 Adjusting the Coring Depth A coring depth of 2-1/2 inches (6.35 cm) is recommended, but you can change the depth as follows: g013076 Figure 12 1.
Securing the Machine for Transport When transporting the machine on a trailer, always use the following procedure: Important: Do not operate or drive the machine on roadways. 1. Drive the machine onto that trailer, stop the machine, stop the engine, turn off the fuel valve, and disconnect the spark plug wire. Important: If you do not turn off the fuel valve, the engine may flood during transport. 2. Secure the machine to the trailer with chains or straps using the tie-down/lift loops (Figure 5).
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Change the engine oil. After the first 10 hours • Check the tension of the drive chains. After the first 25 hours • Check the tension of the hydrostatic drive belt. Before each use or daily • • • • Check the engine oil level. Lubricate the pivot arms. Check the tire pressure. Check the condition of the coring tines and replace any that are damaged or excessively worn.
WARNING Mechanical or hydraulic jacks may fail to support machine and cause a serious injury. • Use jack stands when supporting machine. 1 • Do not use hydraulic jacks. g017585 Figure 15 WARNING If you operate the machine with the rear access panel removed, some one could be severely injured by contact with the moving tines or by flying debris. Always securely install the rear access panel before operating the machine.
Lubrication engine to flood and the air cleaner to be fouled with gasoline. Greasing the Center Tines Service Interval: Before each use or daily 1. Raise the tines, stop the machine, stop the engine, and disconnect the spark plug wire. 2. Remove the rear access panel; refer to Accessing the Tines (page 13) 3. Manually rotate the 2 center tine assemblies until you can see the grease fittings (Figure 17). 1 g013292 Figure 18 1. Chain (left side shown) 3.
Engine Maintenance 7. Install the foam pre-cleaner onto the paper air filter. Note: Use a new paper air filter if you discarded the old one. Servicing the Air Cleaner 8. Install the air filter assembly and cover. Service Interval: Every 25 hours—Clean the foam pre-cleaner (more frequently in dusty conditions). Changing the Engine Oil Every 300 hours—Replace the paper air filter (more frequently in dusty conditions).
1 2 Figure 22 5. Install the new filter and hand tighten it 2/3 turn only. 6. Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight. 7. Slowly pour oil into the oil fill tube, periodically checking the level with the dipstick, until the dipstick indicates that the engine is full. Do not overfill. (Max. fill: 20 oz. (0.55 l), type: SAE 30W detergent oil with an API service classification of SH, SJ, SL, or higher.) g017582 Figure 21 1. Oil drain plug 2.
Fuel System Maintenance Replacing the Fuel Filter Service Interval: Every 250 hours 1. Stop the engine and wait for it to cool down. Figure 23 Important: Drain gasoline from a cold engine only. 1. Center electrode insulator 2. Side electrode 3. Air gap (not to scale) 2. Disconnect the wire from the spark plug. 3. Close the fuel valve. 4. Clamp off the fuel line on either side of the fuel filter (Figure 24) to prevent fuel from leaking out when you remove the filter. 6.
Drive System Maintenance 1 Checking the Tire Pressure Service Interval: Before each use or daily 2 Maintain the air pressure in the tires as specified.

Tine Maintenance Note: Ensure that the bail will reach the handle after the transmission is engaged. Checking/Replacing Tines Service Interval: Before each use or daily 1. Raise the tines, stop the machine, stop the engine, and disconnect the spark plug wire. 2. Remove the rear access panel; refer to Accessing the Tines (page 13) 3. Manually rotate the tines on the shaft, inspecting them for wear or damage. 4.
Storage 1. Raise the tines, stop the machine, stop the engine, and disconnect the spark plug wire. 2. Remove dirt and grime from the entire machine. Important: You can wash the machine with mild detergent and water. Do not pressure wash the machine. Avoid excessive use of water, especially near the engine and hydrostatic drive. 3. Service the air cleaner; refer to Servicing the Air Cleaner (page 16). 4. Grease the chains and floating tine assemblies; refer to Lubrication (page 15). 5.
