Safety 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 always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death. 1 Safe Operating Practices m–5082 This product is capable of amputating hands and feet.
• Do not exceed the rated operating capacity, as the traction unit may become unstable which may result in loss of control. • Raising the loader arms on a slope will affect the stability of the machine. Whenever possible, keep the loader arms in the lowered position when on slopes. • Do not carry a load with the arms raised. Always carry loads close to the ground. Do not step off of the platform with the load raised. • Removing an attachment on a slope will make the rear of the traction unit heavy.
• Before and while backing, look behind and down for small children. • Battery gases can explode. Keep cigarettes, sparks and flames away from the battery. • Never carry children. They may fall off and be seriously injured or interfere with safe traction unit operation. • Keep your body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid. Use cardboard or paper to find hydraulic leaks.

Stability Data The following table lists the maximum slope recommended for the traction unit in the positions listed in the table. Slopes over the listed degree may cause the traction unit to become unstable. The data in the table assumes that the loader arms are fully lowered and that the factory installed tires are on the traction unit, inflated to the recommended pressure; raised arms and other tire types or pressure may affect the stability.
Before Operating Important Never use fuel additives containing methanol or ethanol. Before operating, check the fuel and oil level, remove debris from the traction unit, and check the tire pressure. Also, ensure that the area is clear of people and debris. You should also know and have marked the locations of all utility lines. Note: The two fuel tanks will run empty equally; however, you must fill them separately because filling one will not fill the other. Adding Fuel 1.
6. Pull the dipstick out and look at the metal end. high-pressure washer. High-pressure washing can damage the electrical system and hydraulic valves or deplete grease. 7. If the oil level is low, clean around the oil filler cap and remove the cap (Fig. 5). 7. Install the hood; refer to Installing the Hood, page 23. 8. Slowly pour only enough oil into the valve cover to raise the level to the F (full) mark. 8.
Tire pressure 1 Maintain the air pressure in the tires as specified. Check the tires when they are cold to get the most accurate reading. Pressure: 15-20 psi. m–1872 Note: Use a lower tire pressure (15 psi.) when operating in sandy soil conditions to provide better traction in the loose soil. Figure 7 1. Valve stem Operation Note: Determine the left and right side of the machine from the normal operating position. Traction Unit Overview Figure 8 contains a front and back view of the traction unit.
Choke Lever Caution Before starting a cold engine, move the choke lever fully forward. After the engine starts, regulate the choke to keep the engine running smoothly. As soon as possible, move the choke lever rearward as far as possible. A warm engine requires little or no choking. You could fall off of the platform and be seriously injured during operation. Do not move the control levers unless you are standing with both feet on the platform and your hands are holding the handles.
Move the speed selector lever to the slow (turtle) position to set the auxiliary hydraulics to high speed and the traction drive, loader arms, and attachment tilt to low speed. 1 2 5 3 Warning 4 Figure 10 If you move the speed selector lever while the traction unit is in motion, the traction unit will either stop suddenly or accelerate quickly. If you operate the traction unit with the speed selector lever in an intermediate position, the traction unit will operate erratically and may be damaged.
Important Do not engage the starter for more than 10 seconds at a time. If the engine fails to start, allow a 30 second cool-down period between attempts. Failure to follow these instructions can burn out the starter motor. Note: The farther you move the traction control levers in either direction, the faster the traction unit will move in that direction. 6. After the engine starts, gradually move the choke rearward.
