ORIGINAL INSTRUCTIONS
Setting the Probe Pressure
Use the PROBE PRESSURE REGULATOR to set the Probe pressure. This adjusts the pressure for the
beam and the force that the probes will use to push into the ground. To adjust pull out on the knob and rotate
clockwise to increase the pressure and counter clockwise to decrease the pressure. The selected pressure will
display on the Probe pressure gauge as long as the system pressure is above the selected pressure. Press
the knob in to lock it in place.
Note: The probe pressure will need to be set to around 50PSI to get the beam to lock.
To select the proper pressure, start with the pressure to around 30-50 PSI. With the Machine on the Inject
screen, press the 2 trigger switches on the handle. The beam should lower and pivot arms should lock, if the
pivot arms do not lock then the pressure will need to be increased. After the beam goes down the probes
should extend. If they do not extend fully into the ground increase the Probe pressure.
If you wish to try and get multilayer breakup in the solid then you will need to adjust the pressure until the
probe stop at this compacted layer. You may need to adjust this multiple times depending on where the
compaction layer is. Some soils do not have a compaction layer, in that case you can adjust the pressure until
the probe fully extends.
The maximum pressure that you can set the probes to is 120 PSI
CAUTION
If the 12 in probes are installed and the ground is severely compacted adjusting the pressure above 80 psi
could result in the machine being lifted. This can be cause the machine to roll if it is on a slope or hill.
Setting the Inject Pressure
Use the INJECT PRESSURE REGULATOR to set the Inject pressure, which is the pressure of the air that
is released underground. To adjust pull out on the knob and rotate clockwise to increase the pressure and
counter clockwise to decrease the pressure. The selected pressure will display on the Probe pressure gauge
as long as the system pressure is above the selected pressure. Press the knob in to lock it in place.
It is recommended to start with a pressure between 30 and 50 psi and adjust to get the desired effect.
Depending on the desired decompaction you may or may not see the ground move when the injections occur.
If there is too much movement of the ground or if the turf is being damaged then reduce the pressure.
It is recommended to start low and increase after testing. Too high a pressures could result in turf
damage or blowouts.
