Operation • Clean grass and debris from the tines, drives, muffler, and engine to help prevent fires. Clean up oil or fuel spillage. • Never run an engine in an enclosed area. • Only operate in good light, keeping away from holes and • Let the engine cool before storing and do not store near flame. hidden hazards. • Shut off the fuel while storing or transporting on trailers. • 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.

Filling the Fuel Tank 1 Capacity: 0.93 L (0.25 US gallons) DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, and when the engine is cold. Wipe up any gasoline that spills. • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck.
• Oxygenated fuel with up to 10% ethanol or 15% MTBE 3. Move the engine switch to the On position. by volume is acceptable. 4. Move the throttle lever all the way forward to the Choke position; refer to Throttle Lever (page 8). • Do not use ethanol blends of gasoline (such as E15 or E85) with more than 10% ethanol by volume. Performance problems and/or engine damage may result which may not be covered under warranty. Note: Do not use the choke when the engine is warm. 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 chain. After the first 25 hours • Check the tension of the transmission drive belts. Before each use or daily • Check the engine oil level. • Check the tire pressure. • Check the condition of the coring tines and replace any that are damaged or excessively worn. • Check for loose fasteners.
Lubrication Lubricating the Drive Chain Service Interval: Every 25 hours 1. Raise the tines, stop the machine, stop the engine, and disconnect the spark-plug wire. 1 2. Raise the front of the machine to gain access to the chain, and block it in place; refer to Tipping the Machine (page 14). G022091 CAUTION Figure 20 If you do not securely block up the front of the machine, the machine could fall on you during service, injuring you. 1.
Engine Maintenance Greasing the Machine Use a grease gun to lubricate the grease fittings on the front axle with general-purpose lithium grease (Figure 23). Servicing the Air Cleaner Service Interval: Every 25 hours—Clean the foam pre-cleaner (more frequently in dusty conditions). Yearly—Replace the paper air filter (more frequently in dusty conditions).
