| Illustration 5 | g01996893 |
Layout of the Instrument Cluster (80) Engine coolant temperature gauge (81) Hydraulic oil temperature indicator (82) Torque converter temperature indicator (83) Brake system indicator (84) Engine tachometer (85) Engine oil pressure indicator (86) Charging system indicator (87) Object handling stability indicator (88) Fuel level gauge (89) Engine coolant indicator (90) Glow plug indicator (91) Air filter indicator (92) Fuel system water separator indicator (93) LCD display (94) Action light (95) Hydraulic oil filter bypass indicator (96) Low fuel | |
| Engine Coolant (80) - The engine coolant gauge will indicate in the red zone and the action light will flash when the engine coolant temperature is too high. Stop the machine at a convenient location and investigate the cause. |
| Hydraulic Oil Temperature Indicator (81) (If Equipped) - The hydraulic oil temperature indicator will illuminate when the hydraulic oil reaches 110° C (230° F). Action light (94) will also illuminate. Operation of the hydraulic functions must be reduced in order to allow the hydraulic fluid to cool. |
| Torque Converter Temperature Indicator (82) - The torque converter temperature indicator will illuminate when the torque converter temperature exceeds121° C (250° F). Action light (94) will also illuminate and the action alarm will sound. Stop the machine at a convenient location and investigate the cause. The torque converter temperature indicator will flash when there is a fault with the torque converter temperature sensor. |
| Brake System Indicator (83) - The brake system indicator will illuminate when there is a low brake pressure. The indicator will always illuminate when the engine is not running. When the engine is running with a fault, the following will occur: The indicator will illuminate, the action light (94) will illuminate and the action alarm will sound. Stop the machine at a convenient location and investigate the cause. On the 422E and the 428E, the brake system indicator illuminates when the brake fluid level in the brake reservoir is low. Stop the machine at a convenient location and investigate the cause. |
Engine tachometer (84) - The tachometer will indicate the engine rpm.
| Engine Oil Pressure Indicator (85) - When the engine oil pressure is low, the following will happen: This indicator will illuminate, action light (94) will flash and the action alarm will sound. If this indicator illuminates perform the following: Stop the machine immediately, stop the engine, engage the parking brake and investigate the cause. |
| Charging System Indicator (86) - The alert indicator illuminates if there is a malfunction in the electrical charging system. If this indicator illuminates, the system voltage is too low for normal machine operation. |
| Object Handling Stability Indicator (87) - This indicator illuminates when the machine reaches the lifting capacity. Action light (94) will also illuminate and the action alarm will sound. |
| Fuel Level (88) - The fuel level gauge will indicate in the red zone when the fuel level is 12.5% of the tank capacity. |
|
| Engine Coolant Indicator (89) - The engine coolant indicator will illuminate when the engine coolant temperature is too high. Action light (94) will also illuminate. Stop the machine at a convenient location and investigate the cause. |
| Glow Plug Indicator (90) - The glow plug indicator illuminates when the glow plugs are active. |
| Air Filter Indicator (91) - The alert indicator will light when the air filter becomes clogged. If this alert indicator comes on, stop the machine and investigate the cause. |
| Fuel System Water Separator Indicator (92) - The alert indicator indicates a plugged fuel/water separator. Action light (94) will also illuminate. Stop the engine and investigate the cause of the fault. |
LCD Display (93) - The LCD will display the hour meter. The LCD will also display a fault when a fault is present. The fault code list is as follows:
| Action Light (94) - Malfunction in a machine system. |
- 271-05 Action alarm current below normal
- 271-06 Action alarm current above normal
| Hydraulic Oil Filter Bypass Indicator (95) (If Equipped) - The hydraulic filter bypass indicator will illuminate when the hydraulic oil temperature is above 42° C (108° F) and hydraulic oil is bypassing the hydraulic filter. Action light (94) will also illuminate. |
|
| Low Fuel Indicator (96) - The low fuel indicator illuminates when the fuel level is at 12.5% of the tank capacity. The indicator will flash when there is a fault with the fuel level sender. |
