Controls Product Overview Become familiar with all the controls (Figure 5) before you start the engine and operate the traction unit. Figure 5 1. Auxiliary hydraulics lever 2. Key switch 3. Hour meter 4. Fuel gauge 5. Indicator lights and glow plug switch 6. Throttle lever 7. Loader arm/attachment tilt lever 8. Parking brake lever 9. Reference bar 10. Traction control Key Switch The key switch, used to start and stop the engine, has three positions: off, run, and start.
The farther you move the traction control in any direction, the faster the traction unit will move in that direction. By moving the lever to an intermediate position (such as, forward and left), you can move the loader arms and tilt the attachment at the same time. To stop, release the traction control. Auxiliary Hydraulics Lever To operate a hydraulic attachment in the forward direction, rotate the auxiliary hydraulics lever rearward and pull it down to the reference bar (Figure 8, number 1).
Fuel Gauge Hour Meter This gauge measures the amount of fuel in the fuel tank. The hour meter displays the number of hours of operation that have been logged on the traction unit. Engine Oil Pressure Light Specifications If the engine oil pressure gets too low, this light illuminates and an audible alarm sounds. If this happens, stop the engine immediately and check the oil. If low, add oil and/or look for possible leaks. Note: Specifications and design are subject to change without notice.
Stability Data The following tables list the maximum slope recommended for the traction unit in the positions listed in the tables. Slopes over the listed degree may cause the traction unit to become unstable. The data in the tables assume that the loader arms are fully lowered; raised arms may affect the stability. In each attachment manual is a set of three stability ratings, one for each hill position.
Operation Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. Note: Determine the left and right sides of the machine from the normal operating position. Important: Before operating, check the fuel and oil level, and remove debris from the traction unit. Also, ensure that the area is clear of people and debris. You should also know and have marked the locations of all utility lines.
