If that happens, because you cannot expect
sufficient compaction, do ground improve-
ment work before proceeding with the com-
paction process. (Fig. 33)
Detection of vibration abnormality
During operation when appropriate vibration
frequency cannot be achieved because of
the specified engine revolution or the loos-
ened drive belt, or when the vibration fre-
quency is too high, it is indicated by the
flashing light. (Fig. 34)
Sensor wire disconnection
(Between acceleration sensor and sensor
panel)
If flashing of red LED and green LED alter-
nates as shown in the figure, please check
the sensor wire because there is a possibili-
ty that it is disconnected. (Fig. 35)
Power cable disconnection
(Between battery and sensor panel)
If there is no power even when the key
switch is turned on, please check because
there is a possibility that the power cable is
disconnected.

Function to detect abnormality
Normal compaction (during compacting)
Green LED lights up when the sensor finds
that the machine is in normal compaction
process. When the revolution goes up, and
compaction starts, the yellow LED
ձ
lights
up, and as the compaction proceeds, the
number of the lighted LEDs increases from
ղ
to
ո
. After the LED light that was cali-
brated with the measured soil stiffness
value lights up, the compaction process
completes. (Fig. 31)
Normal compaction (Compaction limit)
Compaction limit is reached when all the
yellow LEDs from
ձ
to
ո
have lit up and
the red LED lights up. At this point, this ma-
chine cannot do any further compaction. If
higher soil stiffness value is required, please
use a machine of higher level. (Fig. 32)
Detection of ground trouble and soft ground
For a case of unstable ground or soft
ground (soil containing clay) for which the
use of this machine is not suitable, only the
red LED lights up, with no yellow LED illumi-
nated.
