BRAKE OIL PRESSURE CAUTION PILOT LAMP
This lamp (5) warns the operator that the brake oil pressure
has dropped.
When carrying out checks before starting:
When the engine is stopped, the brake oil pressure circuit is
not actuated, so the caution pilot lamp and central CHECK
lamp are also off.
When operating:
If the brake oil pressure goes down, the caution pilot lamp and
central CAUTION lamp will flash, and the alarm buzzer will
sound intermittently. If the monitor lamps flash, stop the engine
immediately and check the brake oil pressure circuit.
REMARK
The monitor lamp may flash and go out after approx. 30 sec-
onds immediately after the engine is started. This is because
pressure is being stored in the brake accumulator. It does not
indicate any abnormality.
