Retract Target. In the params row, increase the
value to increase the pressure or decrease the
value to decrease the pressure (adjustment by 10
mA increments is suggested). Make sure to write
the column to “active settings.” Repeat this step until
the pressure is achieved. If the value needs
adjusted by more than 100 mA, contact your Grove
Crane distributor or Manitowoc Crane Care.
b. After the pressure is achieved, make sure to “Save
active to customer” and “Save active to factory.”
Outrigger Jack Extend Pressure
1. Start engine and idle. Extend any outrigger jack until full
stroke of the cylinder is achieved and hold. Slowly
accelerate the engine to full RPM. The reading at LS
port (1, Figure 2-33) should read the value cited in
Table 2-3. If it is not, use the service tool as follows to
adjust.
a. In the Manitowoc Crane Tool, open Tools > EEprom
> View Parameters > Cabin > Solenoid PWM
Control (carrier) > Pressure Sol – Outrigger Jacks
Extend Target. In the
params row, increase the
value to increase the pressure or decrease the
value to decrease the pressure (adjustment by 10
mA increments is suggested). Make sure to write
column to “active settings.” Repeat this step until the
pressure is achieved. If the value needs adjusted by
more than 100 mA, contact your Grove Crane
distributor or Manitowoc Crane Care.
b. After the pressure is achieved, make sure to “Save

Outrigger Jack Retract Pressure
1. Start engine and idle. Retract any outrigger jack until full
stroke of the cylinder is achieved and hold. Slowly
accelerate the engine to full RPM. The reading at LS
port (1, Figure 2-33) should read the value cited in
Table 2-3. If it is not, use the service tool as follows to

params row, increase the value
to increase the pressure or decrease the value to
decrease the pressure (adjustment by 10 mA
increments is suggested). Make sure to write
column to “active settings.”
b. Repeat this step until the pressure is achieved. If the
value needs adjusted by more than 100 mA, contact
your Grove Crane distributor or Manitowoc Crane

c. After the pressure is achieved, make sure to “Save
active to customer” and “Save active to factory.”
Rear Steer Pressure
1. Start engine and idle. Slowly accelerate the engine to full
RPM, operate rear steer switch until reaching an axle
stop, and hold. The reading at LS should port (1,
Figure 2-33) should read the value cited in Table 2-3. If it
is not, use the service tool as follows to adjust.
a. In the Manitowoc Crane Tool, open Tools > EEprom
> View Parameters > Cabin > Solenoid PWM
Control (carrier) > Pressure Sol – Rear Steer Target.
In the
params row, increase the value to increase
the pressure or decrease the value to decrease the
pressure (adjustment by 10 mA increments is
suggested). Make sure to write column to “active
settings.” Repeat this step until the pressure is
achieved. If the value needs adjusted by more than
100 mA, contact your Grove Crane distributor or
Manitowoc Crane Care.
b. After the pressure is achieved, make sure to “Save
active to customer” and “Save active to factory.”
Stop the engine.
Outrigger pinning pressure
1. Start engine and idle. Slowly accelerate the engine to full
RPM, operate pinning extend until end of stroke, and
hold. The reading at LS port (1, Figure 2-33) should read
the value cited in Table 2-3. If it is not, use the service
tool as follows to adjust.
a. In the Manitowoc Crane Tool, open Tools > EEprom
> View Parameters > Cabin > Solenoid PWM
Control (carrier) > Pressure Sol – Outrigger Pinning
Extend Target. In the
params row, increase the
value to increase the pressure or decrease the
value to decrease the pressure (adjustment by 10
mA increments is suggested). Make sure to write
column to “active settings”. Repeat this step until the
pressure is achieved. If the value needs adjusted by
more than 100 mA, contact your Grove Crane
distributor or Manitowoc Crane Care.
2. Repeat procedure for outrigger pinning retract. The
reading at the LS port (1, Figure 2-33) should read the
value cited in Table 2-3. If it is not, use the service tool as
follows to adjust.
