8. With the graduated measuring cylinder in the
same straight line as the pans, evaluate the
volume of material in each cylinder to determine
the quality of the distribution from the spreader.
9. To adjust the spreader pattern, refer to the
Adjusting the Spreader Pattern (page 30) .
10. Fill the hopper half-full of the desired material
and repeat steps
1 through 9 until you achieve
a uniform pattern.
Determining the Effective Spreading Width
Use the effective width to determine the uniform
distribution of the material.
Note:
The spreading width range is 6 to 8 m (20 to
25 ft).
1. After the spreader pattern is correctly adjusted,
evaluate the amount of material in the center
graduated measuring cylinder.
2. Locate the 2 graduated cylinder, one each side
of center, that contain 1/2 the measured amount
of the material that you observed in the center
graduated cylinder.
3. Go to the two corresponding pans. Starting from
the outer edge, measure the distance between
left pan, across the center pan, to the outer edge
of the right pan, and record the measurement.

Preparing the Calibration Course for
Calculating the Application Rate
1. Determine a course length by dividing 93 m 2
(1,000 ft 2 ) by the effective spread width that
you determined in Determining the Effective
Spreading Width (page 25) ; use the course
length formula. Record the course length
here: .
Calibration Course Length Formula
Formula
93 m 2 (1,000 ft 2 )
/ Effective width
measurement
=
Calibration course
length
Example 93 m 2 (1,000 ft 2 )
/ 1.8 m (6 ft)
=
51 m (167 ft)
Note:
In this example the effective width
measures 1.8 m (6 ft).
2. Measure and visibly mark the course length.
Ensure that you allow enough distance before
the starting marker so that the spreader moving
forward at full speed when crossing the first
mark of the course.
Calculating the Application Rate
1. Determine the area and amount of material that
you are applying to the job site and record those
amounts in the area and materials worksheet.
Record the job site area

.

.
2. Initially, use the recommended application rate
indicated in the
Spreading Charts (page 29)
section or use the rate recommended listed on
the product manufacturer’s label as a guide to
help determine the amount of material that you
would spread over a 93 m
2 (1,000 ft 2 ) area.
Note:
In this example the calibration course is
1.8 m (6 ft) by 51m (167 ft).
3. Set the appropriate drop-rate cam setting; refer
to the
Spreading Charts (page 29) as a starting
point.
4. Add material to the hopper.
Note:
In this example we added 11.3 kg (25
lb) of material.
5. Drive the spreader over the calibration course
while applying the material.
6. Empty the remaining material of the hopper into
a clean bucket; refer to
Emptying the Spreader
(page 26) .
7. Weigh the bucket containing the material and
record the weight. Pour the contents back
into the hopper and then weigh the empty
bucket. Calculate the remaining material weight
using the remaining material weight formula.
Record the remaining material weight
here:
.
Remaining Material Weight Formula
Formula
(Remaining
material and
bucket weight) -
(Bucket weight)
= Remaining material
weight
Example 10 kg (22 lb) —
1 kg (2 lb)
=
9 kg (20 lb)
Note:
In this example, 9 kg (20 lb) of material
remain in the hopper after applying the material
to the test course.
8. Calculate applies material weigh using
the applied material formula that follows.
