4.f. ADJUSTMENT OF THE HYDRAULICS
Adjusting the main pressure
Start the motor with max. r.p.m. Press the main valve. The manometer must show 80-120 bar. On soil samplers with a display the pressure
is shown electronically.
The excess-pressure valve which is located under the red cap is for adjusting the main pressure. The main pressure is preset on 120 bar. It
must only be adjusted after signing a written agreement with Wintex Agro.
Adjusting the pressure of the probe
Loosen the lock nut. Adjust the pressure with a 6 mm hex key. Pressure will rise when turning to the right and lower the pressure by turning
to the left. If the hammer will not move down, or if the soil sampler is lifted of the ground when sampling, the pressure must be lowered.
When taking a 0-15 cm sample it can be advantageous to lower the probe pressure which will result in a better sample.
