PIVOTING BOOM HEAD
Boom Head Positions
The pivoting boom head can be adjusted to four angled
positions, in addition to 0°. Two of which are used when there
is no boom extension attached and two when a boom
extension is attached.
Positions When No Boom Extension Is Attached
The plus 40° and plus 80° boom head positions (Figure 5-1)
can be used when there is low head room clearance and a
smaller profile boom head is needed.
Positions When Boom Extension Is Attached
The minus 15° and minus 30° boom angles are used to offset
the boom extension. See Figure 5-2.
