[3] ERROR CODE DISPLAY (CABIN MODEL ONLY)
If trouble should occur at the instrument panel error
code appears as a warning.
If the trouble is not corrected by restarting the
machine, solve the problem according to the following
table.
• This error code is detecting the internal circuit
problem in the instrument panel.

[4] SWITCHES AND SENSORS
Oil Pressure Switch
While oil pressure is high and the force applied to the
diaphragm (2) is larger than the spring tension, the
terminal contact (1) is open separated from the body
contact (3). If the pressure drops below approx. 49 kPa
(0.5 kgf/cm
2
, 7.1 psi), the contact closes.

Fuel Sensor
The remaining fuel quantity is detected by the fuel
level sensor installed in the fuel tank and indicated on the
fuel gauge. For detection, a float and a resistor are used.
As the float (1) lowers, the resistance of the variable
resistor (2) varies. The relation between the amount of
fuel and the resistance is as follows.
