• Check the pressure increase indication on the
gauge.
• Check the pressure decrease indication on the
gauge.
- When the required pressure is reached, close the
valve.
- Check that the ground pressure is identical on the 2
mowing units.
- Adjust hydro-pneumatic accumulator pressure if
necessary.
Proceed the same way for second mowing unit
by inverting opening/closing of mowing unit
suspension valves.
When gauges indicate the same pressure, the
ground pressure of the mowing units is not
necessarily identical.
