Hydraulic Oil Level Buzzer
The hydraulic oil level buzzer is a buzzer that
warns about insufficient oil and is connected
to the level switch on the hydraulic tank.
When the hydraulic oil is less than the
specified quantity, there is continuity in the
level switch, causing a buzzer to sound
[intermittent tone].
The specified quantity is approximately 4.2
dm
3
(4.2 L) (1.11 gal (US)).

Level Switch
The level switch is located on the top of the
hydraulic tank and switches "ON" and "OFF"
according to the rise and fall of the float. (The
arrow indicates the float travel distance.)
Normal operation is when there is continuity
when the float is down and no continuity when
the float is up.

Fuel Pump
The fuel pump is composed of a solenoid,
diaphragm, check valve, etc.
When the key switch is set to the "ON"
position, the solenoid is energized and the
diaphragm operates.
As a result, fuel is repeatedly taken in and
discharged to supply a constant amount of fuel
to the injection pump, regardless of the engine
speed.
