The temperature indicator light Item 6 (Fig. 13, page 48) is
connected to two temperature sensors. One is located on
the engine (Fig. 84), the other on the hydraulic oil reservoir
(Fig. 85). To ascertain whether the engine or hydraulic oil
(or both) have become too hot, disconnect the cable on one
of the two temperature sensors.
In the event of cooling system overheating, check the fol-
lowing:
Is there enough coolant in the radiator and is it the cor-•
rect coolant mix?
Is the fan‘s V-belt taut and in good condition?•
Is the radiator air ow restricted?•
