Calibration Disclaimer
It is the responsibilty of the person using this equipment to make sure that every type of material is properly calibrated to perform
as expected. This process should take place on a solid
fl
at surface away from drains and livestock areas in order to achieve a safe
and accurate reading for proper material distribution. Failure to do so may cause an over/under application that could damage
turf areas or give an ineffective pest control treatment. Any calibration charts contained in this manual are given as a reference
point only and should not be used as an absolute condition. Spending a few extra minutes to properly calibrate will not only save
on wasted materials and time but also protect turf and other vegetation. Below are several points to be aware of before operating
your spreader in the
fi
eld.
• . Flow rates of material can change for many reasons
1. Formualtions vary within the same brand or even between brands
2. Formulations vary between batches or dates of manufacture
3. Humidy can cause the material to clump and
fl
ow poorly
4. Poor spreader maintenance can cause
fl
ow changes
5. Slide stop has moved or calibrated to another type of material
6. Human error can cause rate miscalculation
• Items needed for calibriation
1. A way to catch the material for weighing
2. A device to measure distance
3. A scale to weigh your product
4. A stop watch or other means to measure time
