Cooling Fan Switch
The cooling fan switch is used to control the operation
of the hydraulic cooling fan and is located on the control
console (Fig. 23). This  switch has three (3) positions:
Reverse, Auto and Forward.

When the cooling fan switch is in the normal Auto posi-
tion,   cooling   fan  operation   is   controlled   by   the
TEC--5002 controller. In this switch position, if either en-
gine coolant or hydraulic oil temperature is excessive,
the fan will stop and then reverse direction to allow auto-
matic debris cleaning of the radiator, oil cooler and rear
intake screen. The controller determines  the length of
timethatthefanshouldberuninreversebeforefanrota-
tion is returned to the forward direction.

  1. At only 700mm wide the Mini Dumper is even at home on tight access
    sites. No need to grunt, groan, and force the
    mower about the yard. The US will be getting a revised 2011 Jeep Wrangler but the diesel option will not be offered in the United States.
