Checking the Warning Devices
Be Sure to Check the Warning Devices before Starting the Engine.
If the devices are not working properly, it is impossible to prevent any accidents arising
from problems like insufficient oil and water.
When the warning devices are activated and normal operation is impossible, stop the
engine and do not use it until the problem has been solved.
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 hour meter is displayed.
After Engine Start
After engine start, make sure that the warning devices operate correctly and according to

• 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,
