INDICATOR SWITCH
The indicator switch (1, Figure 5-21) is factory preset

switch will illuminate the amber “Hydraulic Oil Filter”
warning lamp located on the overhead display in the
operator’s cab.

filters, or the steering circuit filter will cause the
Hydraulic Oil Filter warning lamp to illuminate.
The indicator switch is not individually repairable. If
the switch is inoperative, replace with a new part.
