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 dump position
by moving the lever to the right is the
"Regular" dump position.
It has good power and control for dump-
ing 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.
