Booms
The height of the outside boom can be 24” to 76”
from the ground. There are three possible
positions for the outside booms. To have the boom

the boom may need to be changed.
The height ranges from 36” to 76” (90 to 190 cm)
when the boom lift cylinder is secured in position 1,
30” to 70” (75 to 175 cm) for position 2, and 24” to
64” (60 to 160 cm) for position 3.

boom on to a stand to support the weight of the
