PANEL
[1] EASY CHECKER™
If the warning lamps of the Easy Checker™ come on during operation, immediately stop the engine, and find the cause as shown below.
Never operate the machine while Easy Checker™ lamp is on.
Electrical Charge Warning Indicator
If the dynamo is not charging the battery, the warning lamp in the Easy Checker™ will come on.
If this should happen during operation, check the electrical charging system.
Glow Plug Indicator
When the key switch is in the "PREHEAT" position, the glow plug indicator illuminates.
Engine Oil Pressure Warning Indicator
If the oil pressure in the engine goes below 49 kPa (0.5 kgf/cm2, 7 psi), the warning lamp in the Easy Checker™ will come on.
[2] SWITCHES AND SENSORS
Oil Pressure Switch
9Y1211156ELM0020US0
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/cm2, 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.

Coolant Temperature Sensor
The coolant temperature sensor is installed to the cylinder head of engine, and its tip is in touch with the coolant. It contains a thermistor (4) whose electrical resistance decreases as the temperature increases. Current varies with changes in the coolant temperature, and the increases or decreases in the current move the pointer of gauge.
