4.3 Standoff Adjustment Procedure
The term “Standoff” refers to the height of the
spray bar above the pavement. The standoff dis -
tance is set by turning the adjustment handle on
the threaded end of each caster wheel yoke.
Standoff directly affects removal perfor-
mance and should be adjusted regularly
based on the following considerations:
• Removal performance. Generally the best
standoff distance is 1.5” (3.5 cm) from the
spray bar to the pavement; 1.25” (3.2 cm)
from the nozzle to the pavement; and .75”
(2 cm) from the spray bar protector to the
pavement. This is the standard factory setting.
• Clearance for obstacles. The standoff should
always be set high enough to provide enough
clearance for the shroud and spray bar to clear
obstacles permanently attached in the pave-
ment, such as runway lights or road markers.
It is the operator’s responsibility to evalu-
ate the pavement surface and permanently
attached obstacles, then set the standoff
adjustment to provide clearance at the start
of each job. Since pavement obstacle height
is unique to each location, never assume that
the standoff has been correctly set by any other
person or operator who have previously used the
truck in a similar circumstance.
To set the standoff distance:
1. Make sure the yokes are correctly installed
and locked into position.
