With engine at LOW IDLE and warm, the low pressure warnings for both engine and primary steering should go off within 15 seconds. If either do not go off, stop the engine immediately and investigate.
1. Keep the engine at LOW IDLE until the engine oil pressure indicator goes off.Observe all gauges, warning and service lights frequently during operation. All gauges should indicate in the proper range and all warning and service indicators should be off.2. Operate the engine 900-1200 rpm for the time shown below. Do not engage any controls during this time.A. Below 0°C(0°F) 15 Min.B. 0°C to -18°C (-0°F to 32°F) 10 MinutesC. 0°C to 21°C (-32°F to -70°F) 5 Minutes3. The low air pressure alarm will sound until the service brake/retarder air reservoirs are charged to approximately 415 kPa (60 psi).If the EMS warning horn is sounding and air pressure is good, the coolant flow alarm may be sounding. Stop engine immediately and check coolant level. Check the EMS panel to determine if this is the cause.If so, stop the engine and check the coolant level. 4. The alternator indicator (1) should be off. If it stays on after engine is running, stop the engine and investigate.5. If the transmission oil filter indicator (2) is on continuously with warm oil, stop the engine and service the transmission and torque converter filters.To provide maximum sound suppression on machines equipped with sound suppressed cabs, keep all doors and windows closed.Check the following engine oil, steering transmission, hoist, converter and brake oil levels with the engine at LOW IDLE and the oil at normal operating temperature. 6. Check the engine crankcase oil level. Maintain the oil level between the ADD and FULL marks on the ENGINE RUNNING side of the dipstick. 7. Check the steering system hydraulic oil level.If the oil level registers in the operating range at lower gauge, then the accumulators are properly charged.If it registers below the operating range mark in lower sight gauge, it is incorrectly precharged. See your Caterpillar dealer for charging procedures.If oil must be added, stop the engine and wait for accumulators to discharge. Oil will raise as accumulators discharge. To prevent overfilling always add oil with engine off accumulators discharged. 8. Check transmission sight gauge (1) with cold oil, engine idling. Check transmission sight gauge (3) with warm oil, engine at LOW IDLE.Check the hoist converter and brake sight gauge (2) when the engine is running and the oil is warm. Maintain the oil level to the FULL WARM marks in sight gauges (1) and (2).Observe all gauges, warning and service lights frequently during operation. All gauges should indicate in the proper range and all warning and service indicators should be off.Testing the Secondary Brake System
Test operation of secondary brake system daily, or at the beginning of each shift. This is a test to determine if the secondary brake system is functional. This test is not intended to measure maximum brake holding effort. Brake holding effort required to hold a
