D. Procedure for Checking/Setting Cab Tilt
Raise and Lower Pressures
With the engine off, install pressure check diagnostic quick
disconnect (Parker PD240) with gauge onto test nipple at
GPLS port of the Accessory manifold (Figure 2-15).
12. Cab Tilt Lower:
Start engine and idle. Activate the cab
lower function until full stroke of the cylinder is achieved
and hold. Slowly accelerate the engine to full RPM. The
reading at GPLS should be 725 ±100 PSI (50 ±7 bar) if it
is not use the service tool as follows to adjust.
a.
In the Tools->EEprom->View Parameters->Super-
>Cab Tilt->Tilt Down Pressure params row increase
the value to increase the pressure or decrease the
value to decrease the pressure (adjust 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 adjusting
by more than 100 mA there may be other issues in
the circuit.
b.
Once the pressure is achieved make sure to “Save
active to customer” and “Save active to factory”
13. Cab Tilt Raise:
Start engine and idle. Activate the cab
raise function until full stroke of the cylinder is achieved
and hold. Slowly accelerate the engine to full RPM. The
reading at GPLS should be 1450 ±100 PSI (100 ±7 bar)
if it is not use the service tool as follows to adjust.
a.
In the Tools->EEprom->View Parameters->Super-
>Cab Tilt->Tilt Up 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”
14.
Stop engine. Remove diagnostic couplers.
E. Procedure for Checking/Setting
Counterweight (CWT) Raise and
Lower Pressures
1.
With the engine off, install pressure check diagnostic
quick disconnect (Parker PD240) with gauge onto test
nipple at GPLS port of the Accessory manifold
(Figure 2-15).
2.
Assure that the CWT is not attached to the cylinders and
the superstructure is in a position that the cylinders can
be fully actuated in both directions.
3. CWT Lower:
Start engine and idle. Activate the CWT
lower 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
1450 ±100 PSI (100 ±7 bar) if it is not use the service
tool as follows to adjust.

To Lower The CWT Cylinder
1.
“Press and hold the override button (3).
2.
To extend or lower the cylinder - activate
symbol (1).
3.
Release the override button when done
moving (3).
To Raise The CWT Cylinder
1.
“To retract or raise the cylinder - activate
symbol (2).
2.
Once the cylinder is fully retracted both
symbols (4) should become green.
