Fuel Gauge; Hydraulic Oil Temperature Gauge; Coolant Temperature Gauge; Tachometer - Hitachi EX1900-5 Operator's Manual

FUEL GAUGE

Fuel machine before needle reaches "E".
When the needle reaches "E", approximately 300 liters (79
US gal) of fuel remain.

HYDRAULIC OIL TEMPERATURE GAUGE

Start the engine. Run at slow idle until the needle enters
white zone (A).
If needle enters the red zone, reduce the load immediately
and run the engine at slow idle until needle returns the
green zone. If the problem continues, contact your author-
ized dealer.

COOLANT TEMPERATURE GAUGE

Start the engine. Run at slow idle until the needle enters
green zone, indicating normal operating temperature.
IMPORTANT: Prevent possible engine damage.
Do not stop engine when needle enters
red zone, as temperature will rise further.
Instead, reduce load and run engine at
slow idle.
If the needle enters the red zone, reduce the load immedi-
ately and run the engine at slow idle. If problem continues,
inspect for plugged radiator or coolant leakage.
