Boom Folding Procedure
The Front Folding Boom is hydraulically operated,
and is controlled by a single valve block. There are
controls for the vertical elevation, left and right
boom tilt, left and right inner fold and left and right
outer fold.
Boom Folding
The following procedure should be used to fold
the boom.
1. Raise elevator to top position.
2. Fold left and right outer booms 180˚. Make
sure outer booms snap into locks.
3. Raise left and right tilt to uppermost position.
Make sure lock plunger moves up, locking
boom in place.
4. Fold left and right inner booms 90˚.
5. Lower left and right tilt so the booms rest on
the transport supports.
Note: Outer booms will not lock if booms are tilted.
Boom Unfolding
The following procedure should be used to unfold
the boom.
1. Raise left and right tilt to uppermost position.
2. Unfold left and right inner booms 90˚.
3. Lower left and right tilt to lowest position.
Make sure lock plunger lowers out of the way.
4. Unfold left and right outer booms 180˚.
5. Lower elevator to proper spraying height.
Normal boom use may shift the outer boom sup-
port locks along the inner section. When properly
adjusted, the outer arm plate will snap into the
gap between the lock plates, and the holes line
up. Loosen the U-bolts and reposition brackets as
necessary. Adjust cable tension so the plunger is
out of the way when boom is unfolded.
Make sure outer boom cylinder pressure is re-
leased and lock plunger is free to move up and
down before unfolding boom.
