4.3 Stando Adjustment Procedure
The term “Stando” refers to the height of the
spray bar above the pavement. The stando 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
stando distance is 1.5” (46 cm) from the
nozzles to the pavement. This is the standard
factory setting.
• Clearance for obstacles. The stando 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.
It is the operator’s responsibility to evalu-
ate the pavement surface and permanently
attached obstacles, then set the stando
adjustment to provide clearance at the start
of each job. Since pavement obstacle height is
unique to each location, never assume that the
stando has been correctly set by any other per-
son or operators who have previously used the
truck in a similar circumstance.
To set the stando distance:
1. Make sure the yokes are correctly installed
and locked into position.
2. Raise the Hog Arm to the full up with the heads
lock perpendicular to the road surface.
3. Turn o the truck and place it in the service
position to ensure that the head cannot ac-
cidently move.
