OPERATION
Detection of ground trouble and soft ground
1. For a case of unstable ground or soft ground (soil
containing high clay content) for which the use of this
machine is not suitable, only the green and red LEDs
will be on (Figure 24), with no yellow LED's on.
If this occurs it would be challenging to achieve the
desired compaction results. Check to make sure the
ground conditions are prepared to specification before
proceeding with the compaction process.

Detection of Vibration Abnormality
2. When appropriate vibration frequency cannot be
achieved during operation due to improper engine
RPMs (Figure 25) the green LED will flash. When this
occurs check the engine RPMs and the V-belt tension
as it could be loose.

3. If red and green LEDs are flashing alternately as shown
in Figure 26 then please check the sensor wire because
there is a possibility that it is disconnected.

4. If there are no LEDs on or flashing even when the key
switch is turned on then please check the power cable
because there is a possibility it is disconnnected.
