Walk-around Inspection
Make a "Walk-around" inspection of the Shovel. Refer to
page 349 in the Maintenance Section 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.
Check the oil level in both engine oil reserve tanks, see page 326
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 mes-
sage "Engine oil reserve tank 1 (or 2) empty" is being dis-
played on the ECS screen in the operator's cab.
