JOYSTICK VALVE
To begin test operation, slightly move
the control lever from the "N" position.
Slowly raise the loader boom just
enough for the bucket to clear the
ground when fully dumped. Slowly
work through the dump and roll back
cycles.
TWO STAGE VALVE TYPE
This loader control valve has two stage
dump position. The first stage has good
power and control for dumping
precisely. This position should be used
when operating another implement with
the loader's control valve.
The second dump position (to further
right) features greater speed for
dumping. These two position are sepa-
rated by a "Feel" position for your
convenience.
