Checking the Warning Devices
Before and after engine start, make sure that the instruments and warning devices
operate correctly.
If the engine runs out of coolant or lubricating oil and the instruments and warning devices
fail, they can not give you warning to prevent accidents. This can also lead to incorrect
operation and cause further malfunctions of the engine.
Before Engine Start
1. Turn on the battery switch.
2. Push the power switch on.
• All alarm lamps light up for 4 seconds.
• After 4 seconds, the charge lamp and the lubricating oil pressure alarm lamp light up,
and the hourmeter is displayed.
• The alarm buzzer sounds until the engine starts.
After Engine Start
After engine start, make sure that the warning devices operate correctly and according to
"After start" in the below table.
• All alarm lamps turn off. The above check tells you whether the electric circuit for the
alarm lamps and alarm buzzer operate correctly. If they do not operate correctly,
inspection and repair are required. Consult your dealer or distributor for repairs.
