b) Watch the oil pressure warning lamp. If the lamp blinks, it may be the oil pick-up screen is not covered with oil. Check oil level gauge. Add oil to the oil pan, if required. Do not overfill. If level is correct and the status still exists, see your DEALER for possible switch or oil pump and line malfunction. Note : Oil pressure will rise as RPM increases, and fall as RPM decreases. In addition, cold oil will generally show higher oil pressure for any specific RPM than hot oil. Both of these conditions reflect normal engine operation. c) Watch the engine water temperature gauge and be sure there is proper water circulation.
The water temperature gauge needle will fluctuate if water level in expansion tank is too low. At the end of the break-in period, remove break-in oil and replace the oil filter. Fill oil pan with recommended engine oil. Refer to following table. 4.2.3. Operating after break-In When starting a cold engine, always allow the engine to warm up gradually. Never run the engine at full throttle until the engine is thoroughly warmed up. Be sure to check the oil level frequently during the first 1,000km(50 hours) of operation, since the oil consumption will be high until the piston rings are properly seated. 4.2.4. Engine oil Check oil level with the oil level gauge and replenish if necessary.
Check the oil level with the engine cooled. If the engine is warm, allow time for 5 ~ 10 minutes Min. lines on the gauge. Engine oil should be changed at the specified intervals. Oil in the oil filter should be changed for oil drain into the crankcase before checking oil level.The oil level must be between Max and simultaneously. * If long oil change intervals are to be used, ACEA-E3 oil must be used. - 100 - COMMISIONING AND OPERATION First oil change After 1,000 km 50 hr operation Construction Equipment DE12T/TI/TIA 250 hr DE12TIS 250 hr The following oils are also recommended Engine model Recommend oil SAE No. API No.
