Walk-around Inspection
Make a"Walk-around" inspection of the Shovel. Refer to Mainte-
nance Section 4. for the daily inspection items.
Check engine oil level in oil pan
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).
Check engine oil level on shovels equipped with the engine
oil reserve system
The oil level in the engine oil pan can vary between the MIN and
MAX marking on gauge (1) depending on the operating condition
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 the reserve system is monitored by an indicator light
located on the "X2" switch board in the cab base. See section
"SWITCH BOX (X2) IN CAB BASE" on page 147 for more infor-
mation.
REMARK
Check also the engine oil level in the engine oil reserve tank,
see page 64 for more information.
