all essential parts
are in place, and
that all fasteners

Figure 1 - Operating Controls
Check for clearance before releasing trough for cleaning� It may swing open suddenly�
Material in the trough will dump quickly� Failure to follow this requirement may result in
injury or machine damage�
Position the rear cover vertically and secure with the pivot rods�
Adjust the dump body’s tailgate chains to hold the tailgate in the required position� This adjustment is
by trial and error and depends on the flow characteristics of the material being spread. The gate should
be open only enough to keep the material freely flowing to the auger. The tailgate should not touch the
rear cover�
Make sure trough bottom is secured before filling with material to be spread.
A wide open tailgate on certain materials will tend to stall the auger resulting in uneven delivery
of material. With free flowing salt, the tailgate may be chained with only a 3” (7.6cm) or 4” (5.1cm)
opening�
If the material to be spread is not already in the dump body, have the unit loaded� With On-Off
control in Off position, engage pump drive and allow oil to circulate until it is warm� This may be done
while traveling to loading or starting point� The colder the weather, the more important this warm-up
becomes�
All spinner adjustments must be made with On-Off control in Off position to stop spinner and auger to
avoid injury from spinner and/or discharging material�
Set variable speed spinner control to obtain spread width desired� Spinner speed and position, as well
as material granule size, density and moisture content affect spread width, so proper settings are gained
by trial and experience�
Spinner speed selected should be the lowest required to obtain the desired spread width with the
material being spread� Use of higher spinner speeds will increase wear and tear on parts� It will waste
material, and can create excessive damage to vehicle finish through uncontrolled throwing and bounce
of materials�
