Servicing Intervals
Every 10 operating hours
Check oil level in the engine oil pan with Excavator stand-
ing on level ground, using oil level gauge (1). Check also
oil level in the reserve tank, see illust. Z23083.
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 pumping unit (12) is monitored by an indicator light
located on the "X2" switch board in the cab base. See section
"SWITCH BOX (X2) IN CAB BASE" for more information.
Be sure to fill the reserve tank when the information mes-
sage
"Engine oil reserve tank empty" is being displayed on
the ETM screen in the operator's cab.
