Hour Meter
The hour meter is located on the outside of the control
arm.
1. Remove control arm covers to gain access to hour
meter and meter terminals (see Control Arm Disassem-
bly in the Service and Repairs section of this chapter).
2. Make sure ignition switch is in the OFF position. Lo-
cate the hour meter and disconnect the wire harness
electrical connector from the meter.
3. Connect the positive (+) terminal of a 12 VDC source
to the positive (+) terminal of the hour meter.
4. Connect the negative (--) terminal of the voltage
source to the other terminal of the hour meter.
5. The hour meter should move 1/10 of an hour every
six minutes.
6. Disconnect the voltage source from the hour meter.
7. Replace the hour meter if necessary.
8. Connect harness electrical connector to the hour
meter.
9. Install control arm covers to machine (see Control
Arm Assembly in the Service and Repairs section of this
chapter).
Temperature Gauge
The temperature gauge on the control panel indicates
engine coolant temperature level during machine op-
eration. The changing resistance of the engine tempera-
ture sender signals the temperature gauge.
The temperature gauge should display the first green
segment when the ignition switch is turned to RUN. The
first yellow segment on the gauge should display when
engine coolant temperature is approximately 212
o
(100
C).
When engine coolant temperature rises to approximate-
o
o
ly 221
F (105
C), the temperature gauge should display
the first red segment. At this point, the temperature
gauge provides an input to the Electronic Control Mod-
ule (ECM). This ECM input causes the high temperature
warning light on the control panel to illuminate and the
cutting reels to shut down.
