OPERATING SECTION 4 Page 9 INSTRUMENT PANEL 7. HYDRAULIC OIL FILTERS WARNING LIGHT The hydraulic oil filter warning light will glow amber when the oil filter element reaches the maximum allowable restriction. When this happens, respective filter service is required. 8. TRANSMISSION MAIN LOW PRESSURE AND CLUTCH LOW OIL PRESSURE WARNING LIGHT The transmission clutch low oil pressure warning light will glow when there is insufficient oil pressure in neutral position or insufficient oil pressure available for the transmission clutches with transmission in gear. When warning light is activated stop the engine and clean transmission system suction filter and check oil level in rear frame.
Refer to “TRANSMISSION SYSTEM” in Section 5. If the light continues to glow stop the engine and consult Authorized Distributor of Construction Equipment before operating the machine. 9. ENGINE COOLANT TEMPERATURE GAUGE This gauge shows the temperature of the coolant circulating through the engine. After the engine has operated a sufficient length of the time, the pointer of the gauge must be in the GREEN area of the gauge. During normal operation the gauge readings may vary between the minimum and maximum indicated by the GREEN area of the gauge. Continuous engine operating below the minimum temperature is harmful to the engine.
Low coolant temperatures will also cause exhaust smoke and increase the rate of fuel consumption. NOTE: In cold weather, if no louver is mounted, it may be necessary to cover part of the radiator to maintain the minimum coolant temperature indicated at the lower end of the GREEN area. The engine temperature under full load should remain in the GREEN of the gauge. 10. ENGINE OIL PRESSURE GAUGE This gauge shows the pressure at which the lubricating oil is circulating through the engine. The pointer must register in the green area during operation of the engine. The gauge only QSK-19C is equipped with red warning light. When red warning light is on, the engine must be immediately be stopped.
11. LOW ENGINE OIL PRESSURE WARNING LIGHT (ENGINE QSK-19) The warning light will glow red when engine lubricating oil pressure drops below permissible minimum value. If so, stop operating the machine and stop the engine. 12. TRANSMISSION SYSTEM OIL TEMPERATURE GAUGE This gauge shows the temperature of oil in transmission system. The pointer of the gauge must be in the GREEN area of the gauge. 13. VOLTMETER The voltmeter indicates the condition of the batteries. At low idle speed, the gauge pointer should be within the green with white stripe area, which indicates a good battery charge. If the voltage drops below this area, the batteries should be checked.
With the engine operating above low idle speed, the pointer should be within the upper green area, which is the normal operating range. If the pointer drops below or exceeds this area, the battery, alternator or wiring may be at fault. 14. LOW ENGINE COOLANT AND LOW OIL PRESSURE ALARM This alarm will sound when lubricating engine oil pressure or coolant level in radiator drops below normal. If so, stop the machine and find out which warning light glows and check gauge indication. DRESSTA TD-40C
