Coolant Temperature Gauge; Fuel Gauge; Hst Oil Temperature Gauge - Hitachi ZW 120-6 Operator's Manual

Coolant Temperature Gauge

The engine coolant temperature is indicated with a needle.
When the needle stays in range (1) during operation, the
coolant temperature is normal.
If the engine coolant temperature becomes abnormally
high, the service indicator will flash and the alarm buzzer
will sound. Stop machine operation and run the engine at
low idle to lower the coolant temperature. After the coolant
temperature lowers, stop the engine for inspection. In case the
needle does not move at all, error in the electrical system is
suspected. Consult your nearest authorized dealer for machine
inspection.

Fuel Gauge

The remaining fuel amount is indicated by the needle.
Refuel before the needle reaches in the red range "E".
When the needle reaches in the red range (E), the fuel level
indicator lights.
f
NOTE: The fuel level indicator may light even if the indicator
needle does not reach the red range (E), depending on the tilt
angle of machine.

HST Oil Temperature Gauge

The HST oil temperature is indicated with a needle. When the
needle stays in range (3) during operation, the oil temperature
is normal. If the HST oil temperature abnormally increases to
range (2) and is kept higher than the specification for a short
period of time, the service indicator comes ON. Stop machine
operation and run the engine at low idle to lower the oil
temperature. After the oil temperature lowers, stop the engine.
