Safe Operating Practices Safety The following instructions are from ANSI standard B71.4-2012. Improper use or maintenance by the operator or owner 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. Training • Read the Operator's Manual and other training material.
Operation Safe handling of fuels • Lightning can cause severe injury or death. If • To avoid personal injury or property damage, use lightning is seen, or thunder is heard in the area, do not operate the machine; seek shelter. extreme care in handling fuel. Fuel is extremely flammable and the vapors are explosive. • Do not run an engine in an enclosed area. • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
• Use care when checking the tines. Wrap the tine(s) • • • • • • • • occur. The operator is responsible for safe operation on slopes. • Use Figure 3 to help you determine the appropriate slope angle of area to aerate. • Remove or mark obstacles such as rocks, tree limbs, etc. from the aerating area. • Watch for holes, ruts, or bumps. or wear gloves, and use caution when servicing them. Only replace tines; do not straighten or weld them.
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.

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 g025899 (gasohol) 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.
Using Stabilizer/Conditioner 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. Use a fuel stabilizer/conditioner in the machine to provide the following benefits: • Keep fuel fresh during storage of 90 days or less. For longer storage, drain the fuel tank.
Lubricating the Chains 3. If the ns pop or snap; refer to Adjusting the Jackshaft Drive-Chain Tension (page 41), Adjusting the Drive Wheel Chain Tension (page 42), or Adjusting the Tine Drive Chain (page 51).

Hydraulic System Maintenance level depending upon the temperature of the fluid. The fluid level varies with the temperature of the fluid. The Cold level shows the level of the fluid when it is at 24°C (75°F). The Hot level shows the level of fluid when it is at 107°C (225°F). For example: If the fluid is at ambient-air temperature, about 24°C (75° F), fill only to the Cold level. If the fluid is about 65°C (150° F), fill to halfway between the Hot and Cold levels.
9. Add the specified fluid until the level reaches the Cold fill line located on the reservoir tank; refer to Checking the Auxiliary Hydraulic-Fluid Level (page 47). 3. At the front of the auxiliary hydraulic pump, remove the inlet hose from the hydraulic fitting in the pump, place the end of the hose in a drain container, and allow the fluid to drain (Figure 56). 10. Start the engine and raise and lower the tines. 11. Lower the tines to the ground and refill the reservoir to the Cold fill line.
4. If necessary, add the specified transmission fluid until the fluid level is at the Full Cold line of the expansion tank (Figure 58). 5. Replace expansion-tank cap and tighten it until snug. 7. Apply a thin coat of specified fluid onto the seal of the new transmission filter. 8. Install the filter by rotating it clockwise onto the filter adapter until the seal contacts the base of the adapter, then tighten the filter an additional 3/4 to 1 turn (Figure 59).
8. Start the engine and move the throttle midway between the SLOW and FAST positions 9. Disengage the parking brake. 10. Slowly move the motion-control levers in the forward and reverse directions 5 to 6 times. Note: Cycling the traction-controls forward and reverse purges air from the transmissions. 11. Shut off the engine and remove the key. 12. Check the fluid level in the expansion tank, and add the specified fluid as required; refer to Checking the Transmission Fluid Level (page 48).
