OPERATION 3.8 CHECKS BEFORE STARTING THE ENGINES Before starting the Engines, make sure that no one will be endangered when starting the Engines. CHECK THE FOLLOWING ITEMS Legend for illustration Z 22468 (1) Engine oil pan dipstick oil level gauge (2) Oil filler tube for engine oil pan (3) Coolant expansion tank of front and rear engine radi- ators (4) Coolant level sight gauge on front and rear coolant expansion tanks (5) Cover plates on power house roof above front and rear radiator pressure caps (6) Radiator pressure caps Walk-around Inspection Make a ”Walk-around” inspection of the Shovel. Refer to Mainte- nance Section 4. for the daily inspection items.

Engine oil level of Front and Rear Engine Check oil level with Shovel standing on level ground. Check oil level in engine oil pan with the dipstick oil gauge (1). For accurate readings, the oil level should not be checked until the oil has set- tled into the oil pan after the engine has been shut down (about 5 minutes). REMARK The oil level in the engine oil pan can vary between the MIN and MAX marking on gauge (1) depending on the operating con- dition of the reserve system when the engine was stopped. With sufficient oil in the reserve tank and with the reserve system in proper working order, there is no need to fill the engine oil pan even with the oil level at the MIN mark on gauge (1).

If the oil level is below the MIN marking on the gauge, corrective action must be taken. Fill the reserve tank and check the reserve system. The function of each reserve system is monitored by an indicator light located on the "X2" switch board in the cab base. See section "SWITCH BOARD (X2) IN CAB BASE" for more information. Be sure to fill the corresponding reserve tank of rear engine -1- or the reserve tank of front engine -2- when the information message "Engine oil reserve tank 1 (or 2) empty" is being dis- played on the ECS screen in the operator’s cab. 205 CAUTION
