Boom Operation
Unfolding the Boom
Assure that the area is clear of all people before unfold-
ing boom. Failure to do so could cause bodily injury
to anyone hit by an unfolding boom.
The first time the boom is operated should be in an open
area so that any air in the hydraulic system can be purged
from the lines. Air in the lines can cause erratic or exces
-
sive speed in unfolding. Move the sprayer to a flat area
with sufficient clearance to unfold the boom.
Chains must be removed before unfolding boom.
Failure to do so will result in damage to the boom.
Remove the chains from the boom before unfolding.
The transport locks must be removed from the “Hi-Lift link
-
age” to allow the boom to lower to the operating position.
The boom hydraulics are activated by the tractor hydraulic
system, but controlled by the boom control panel. The
tractor remote should be set to run at ¼ to ½ speed and
should be shifted to the pressure detent position for normal
operation. Activate the boom lift switch on the boom control
panel (as shown in Fig. B2) to raise the boom and allow
the locks to be removed. Remove the Hi-Lift locks from
the cylinders and store on the upper link. When moving
from field to field, return the locks to the transport position
and lower the boom onto the locks to reduce strain on the
boom and lift components.

The boom control panel contains three major sections:
the left boom controls, the right boom controls and the
combined boom controls.
With the boom chains removed and the sprayer in an open
area, the boom is ready to be unfolded. It is possible that
air could be in the hydraulic lines the first time the boom
is unfolded.
Note: Be aware that air in the lines can cause
the boom to unfold erratically or with excessive speed.
