CALIBRATION
1. Ensure the control handle is fully back (clutch disengaged, shutter closed).
2. To calibrate your spreader, place a measured amount of product (10 Kg) in the hopper.
1. Set the Shutter Stop Lever to the position (1-9) indicated in the Calibration Guides below. Hole position 9
(shutter fully open) is denoted by two holes vertically one above the other.
2. Tow the spreader at the desired speed and pull the control handle forward to engage the clutch and
open the shutter.
3. When the product has been exhausted, measure the distance covered and band width in metres. It is
recommended that this be done over an area where the product can be seen on the ground so that the
spread width can be measured.
4. Check the application rate using the following formula:
Rate (Kg/ha) =
product applied (Kg) x 10,000
distance travelled (metres) x spread width (metres).
5. Adjust either the Shutter Stop Lever or the speed of travel until the desired application rate is achieved.
NOTE
Because of variations in product characteristics, speedometer calibration and driving speed, the information
in the calibration guide should be regarded as a starting point only. It is recommended that the spreader be
calibrated before use.

Magnesium Oxide
Magnesium Oxide powder is applied at a rate determined by the number of cows to be treated. When
spreading this product, calculate the weight of powder to be applied and apply this amount using shutter
setting 4 or 5. Because this product may set hard if left exposed to air, it must not be stored in the machine
even for a short time. Load the spreader only with the amount required to be spread and clean
all
traces of
product from the machine after use.
