Operation - Section 3 10/00 OM3023 Page 3-18 Operating Instructions This switch is used to limit the highest speed range when the transmission shift lever is in "D" or "L" Ranges. Shift Limiter Switch (2, Figure 3-2) This switch (4) actuates the emergency steering pump. Emergency Steering Switch (4, Figure 3-2) Depress the center but- ton to activate the emer- gency steering pump motor. POSITION: "D" Range - F2 - F7 "L" Range - F1 - F2 Depress the button again to turn OFF the emergency steering. When the switch is "On", the RED lamp in the switch will light. The red warning light on the right- hand side of the instrument panel will also light.
"D" Range - F2 - F6 "L" Range - F1 When the switch position is "out" the light is "off".When the switch position is "in" the light is "on". This switch activates a part of the electronically controlled engine fuel system. The switch controls optimum operating efficiency in loaded vs. unloaded conditions. Economy / Power Mode Switch (3, Figure 3-2) Do not use the emergency steering for longer than 90 second intervals and do not drive in excess of 5 km/hr (3 mph). Use this operation ONLY in emergency situa- tions. Do not use this function for normal body operation. When the emergency steering is actuated, it is possi- ble to use the dump lever to raise the dump body.
However, the body cannot be raised when loaded. Normal Idle - When in "Economy Mode" (in/light on), fuel usage is reduced as full engine power is not required. Emergency steering will be activated automatically if the steering pump fails or the engine stops during operation. Advanced Idle - When switched to "Power Mode" (out/light off), full fuel flow is allowed to provide maximum rated engine power. NOTE: This switch also affects the transmission shift points from F1 to F2, and F2 to F1: "Economy Mode" Upshift (F1 to F2) = 2000 RPM. Downshift (F2 to F1) = 1300 RPM.
If the emergency steering automatically actuates, stop the machine as quickly as possible and carry out an inspection to determine the cause. Notify maintenance personnel immediately. "Power Mode" Upshift (F1 to F2) = 2100 RPM. Downshift (F2 to F1) = 1400 RPM. If the key switch is turned ON when the machine is stopped and the parking brake switch is OFF (unlocked position), the auto emergency steering will be actuated after 1.5 seconds. Turn the parking brake switch to the PARKING (ON/ locked) position. is
