a. In the Tools->EEprom->View Parameters->Super-
>Counterweight->Lower Pressure 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 there
may other issues in the circuit.
b. Once the pressure is achieved make sure to “Save
active to customer” and “Save active to factory”
4. CWT Raise: Start engine and idle. Activate the CWT
raise function (Figure 2-39) until full stroke of the
cylinder is achieved and hold. Slowly accelerate the
engine to full RPM. The reading at GPLS should be
3200 ±100 PSI (221 ±7 bar) if it is not use the service
tool as follows to adjust.

5. Stop engine. Remove diagnostic couplers.
F. Procedure for Checking/Setting Swing
Pressure
1. With the engine off, install a pressure check diagnostic
coupler (Parker PD240) with gauge onto the diagnostic
nipple at the MP port of the swing control valve (see
Figure 2-40).
2. Start engine and idle. Depress and hold the swing brake
pedal. Feather into the swing function (left or right) until
full controller stroke is reached and hold. Slowly
accelerate the engine to full RPM. The reading at MP
should be 2750 ±50 PSI (190 ±4 bar) if it is not adjust the
swing relief (Figure 2-40) “in” to increase or “out” to
decrease until the reading is achieved.
3. Move controller to center position before disengaging
the swing pedal.
4. Stop engine. Remove the diagnostic coupler.
G. Procedure for Checking/Setting Outrigger
Pressure
1. With the engine off, install a pressure check diagnostic
coupler (Parker PD240) with gauge onto the diagnostic
