4.3 Standoff Adjustment Procedure
The term “Standoff” refers to the height of the
spray bar above the pavement. The standoff
distance 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” (46 cm) from the
nozzles 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 shrouds and spray bars to
clear obstacles permanently attached in the
pavement, such as runway lights or road
markers.
Standoff Adjustment & Standard Setting
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 per -
son or operators 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.
2. Raise the Hog Arm to the full up position and
install the safety pin.
3. Adjust the Hog Head so it is perpendicular to
the road surface.
4. Turn off the truck and place it in the service
position to ensure that the head cannot ac-
cidently move.
