Adjustment Of Boom Folding Speed - Hardi MEGA VPZ NK Original Instruction Book

4 - Sprayer Setup

Adjustment of Boom Folding Speed

The main hydraulic block manages hydraulic pressure for the boom
controls.
The throttle valve (A) can adjust the folding speed of the boom.
Check the Folding Speed
• Unfold the boom.
• Fold the outer boom sections calmly into the transport position
without crashing hard against the other boom sections.
The folding speed is set from factory - however it may be adjusted
before use of the sprayer if the operator finds it necessary.
Factory setting:
The valve is screwed completely in and 1/2 turn back out.
ATTENTION! The throttle valve only needs slight adjustments to
change the speed significantly.
ATTENTION! If the boom moves to fast:
Risk of premature wear and tear.
Risk of damaging the boom parts.
To Decrease Folding Speed
• Loosen the counternut.
• Screw the valve inwards.
• Tighten the counternut again.
To Increase Folding Speed
• Loosen the counternut.
• Screw the valve outwards.
• Tighten the counternut again.
