Fertilizer and Lime Spreader Pressure Settings for Spinners
1) Checking Pressure
A) Run unit empty at ordinary operating speed (engine RPM’s) for
approximately 10 minutes. This allows oil to reach operating
temperatures.
B) Shut Tractor Hydraulics off and install pressure gauge into “CF” port
on flow control valve.
(Refer to hydraulic flow control valve drawing – page?)
C)
Set flow control valve on 10.
D) Restart engine
E) With Hydraulics engaged, increase tractor engine RPM’s to ordinary
operating speed.
F) Pressure gauge should read 2000 PSI. If not adjust pressure as
outlined below.
Caution:
When checking pressure, never allow tractor to run over a few seconds
with pump running and gauge installed in line. Once pressure reading is taken
disengage hydraulics immediately.
2) Adjusting Hydraulic Flow Control Valve Pressure:
A) Remove cap nut on flow control valve (located on top of valve)
B)
Using a 5/16” Allen wrench turn adjustment screw “IN” to increase
pressure or “OUT” to decrease pressure.
C) Turn adjustable screw on half turn, and then check pressure setting as
outlined above.
D) Continue this procedure until pressure gauge reads 2000 PSI.
NOTE:
If unable to obtain 2000 PSI contact your local dealer or Chandler
