EV-N-SPRED® Calibration Techniques

How to ensure your spreader is properly calibrated

Make sure the drop holes in the bottom of the hopper are fully open when the Rate Control handle is on #30.
If not, please adjust control cable or control rod to allow for a full open hopper position at #30.

Rod Type Adjustment

1. Open the shut-off so that the drop holes are completely open as illustrated to the right.

2. Review the Control Lever position - if it is set so that the forward edge is at #30, you are calibrated. If not you

need to adjust the control rod at the pivot bracket shown in Fig 1.
A. If your shut-off is not able to open fully as in step #1. Loosen the top nut a few turns, then loosen the lower nut
so that it allows you to push the shut-off open fully. Next tighten each nut so that they contact the pivot bracket
without moving it, and then carefully tighten each nut fully so they do not loosen during use. Recheck adjustment
as outlined in #1 above.
B. If your shut-off is able to open fully as in step #1, but the Control Lever is not at #30. Loosen the top nut a few
turns, then loosen the lower nut so that it allows you to push the Control Lever to #30. Next tighten each nut so
that they contact the pivot bracket without moving it. Carefully tighten each nut fully so they do not loosen during
use. Recheck adjust as outlined in #1 above.

Cable Type Adjustment

1. Open the Control Lever so that the shut-off and drop holes are completely open as illustrated above right.

2. Review the Control Lever position so that the indicator is pointed to #30, if it is your calibration is correct. If not you

need to adjust the control cable at the cable clamp on the underside of the hopper as shown in Fig 2.
A. If your shut-off is not able to open fully as in step #1. Loosen the cable clamp screw slightly so that you can slide
the outer cable out so that the shut-off is fully open. Next tighten the cable clamp screw securely. Recheck
adjustment as outlined in #1 above.
B. If your shut-off is able to open fully as in step #1, but the Control Lever is not at #30. Loosen the cable clamp screw
slightly so that you can slide the outer cable in so that the Control Lever opens to #30. Next tighten the cable clamp
screw securely. Recheck adjustment as outlined in #1 above.

ESTABLISHING A SETTING RATE

Step 1: Use Chart 1 to estimate the number of LBS/1,000 square feet of

coverage (Example: 20 LB bag with 10,000 square foot coverage =

2.0 LBS/1,000 square feet)

Step 2: Find the closest LBS/1,000 square feet in Chart 2 that you estimated

using Chart 1 (Example: 2.0 LBS/1,000 square feet = Spreader
Setting of 13)

METRIC RATE SETTING

Determining a Setting Rate

Use chart below to determine the Setting Rate based on Grams/
Square Meter of coverage as directed on the bag.

All spread widths are determined by the particle size and density.

Below will give approximate spread widths.

The settings furnished on the Rate Setting Matrix are intended as a guide only. Variations in physical characteristics of material applied,
walking speed, and roughness of ground surface may require slightly different spreader settings. Due to the above conditions, EPI
makes no warranty as to the uniformity of coverage actually obtained from the settings listed.
