Boom Unfolding
Negative tongue weight. Do Not unfold the booms if the
sprayer is unhooked from tractor with the sprayer tank empty
or low.
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 desired spraying height.
Normal boom use may shift the outer boom support
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 released and
lock plunger is free to move up and down before unfold-
ing boom.
Boom Fold
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 Tilt
Tilt cylinders are single-acting (hydraulic retract, gravity/
float extend).
On the standard TSF sprayers, the booms are level at full
extension.
Tilt is used for storage and for lifting the booms at obsta-
cles and turns.
Autoboom Operation (Option)
On TSF sprayers with Autoboom, the Tilt cylinders can
extend below boom level. Boom tilt at full extension is
regulated by gauge wheels with pressure transducers.
Consult the Raven manual for detail on Autoboom instal-
lation, setup, adjustments and operations.
