The boom is divided up into three stages and a
breakaway end. These stages need to have their
alignment angles adjusted at each pivot area.
BEFORE YOU BEGIN
• Park the machine on a flat level surface, engage
the parking brake and chock the sprayer wheels.
• Start with the boom in the working (unfolded)
position.
NOTE: It is important that both wings are adjusted
the same. If one wing is adjusted further forward or
back than the other, the boom may not sit level.
YAW ANGLE ALIGNMENT PROCEDURE:
FIRST STAGE
• The first stage yaw angle is ad usted by adding
or removing shim plates from the fold rams
mounted on the centre section at pivot A.

1. Loosen and remove the top two bolts, nuts
and washers holding the fold ram and dampers
together (18 & 19 mm spanner/socket). Loosen
the lower two sets but do not remove them; the
shim plates will need to rest on them.
