The right and left telescoping spray
bars (Figure 7) are mounted in the front spray bar housing. Retracted,
they are behind the center spray bar.
Figure 7:

Swing arms are attached to the side of the paver and support the
telescoping spray bars.
The telescoping spray bars each extend hydraulically up to 48 inches. To
modify spray width, nozzles on the telescoping spray bars can be turned
on or off.
The outer three spray nozzles are turned on or off individually.
The inner nozzles are turned on or off with other nozzles on the
telescoping spray bar in “gangs.”
Avoid damage:
If the telescoping spray bars are allowed to
strike an object, they can cause severe damage to property or the
spray paver. Release of hot emulsion may also occur, which could
injure those near the machine.
Be aware of obstacles during spray
paving.
Center spray bar:
The center spray bar is mounted in the front spray bar
housing. It spans the inside distance between the paver tracks or wheels.
All of the center spray bar nozzles are turned on or off as a single gang.
