To adjust the pressure switch:
N
OTE
:
This procedure is best carried out when the body is full and the half pack proximity switch is
inoperable due to insufficient packer blade travel.
1.
Check the main system pressure and verify that it is correctly set to 2250 psi. Refer to “Adjusting
the Main System Pressure” on page 109.
N
OTE
:
Leave the pressure gauge in place.
2.
Locate the pressure switch (see Figure 3-41) and remove the cap screw plug (see Figure 3-58).
Figure 3-58 Cap screw plug
3.
Insert the allen wrench into the adjustment screw.
4.
With the engine running and the pump switch ON, raise the engine RPM to 1500 and initiate an
AUTOPACK cycle and watch the pressure gauge. Note when the blade begins the RETURN
cycle.
N
OTE
:
If the setting is incorrect, the blade will either RETURN early (before the system pressure
reaches 2150 psi), or it will continue packing the load after system pressure has passed
2150 psi.
5.
If the RETURN cycle initiated early, turn the adjustment screw clockwise to increase the
pressure switch setting. If the AUTOPACK cycle continued past 2150 psi, turn the adjustment
screw counterclockwise to decrease the pressure switch setting.
6.
Repeat step 4 and recheck the pressure reading.
7.
When you are satisfied the pressure setting is correct (100 psi below main system pressure, or
2150 psi), remove the allen key and replace the cap screw plug.
