Boom Height; Pulsation Damper - Hardi NL Series Instruction Book

Boom height

Correct boom height is very important in order to achieve the most
optimal spray pattern. (See Spray Technique book).
Small adjustments of the boom height can usually be made with the 3-
point suspension from the tractor - raising or lowering the sprayer.
In crops where greater adjustments are needed the boom height can
be changed manually by removing the 4 bolts holding the boom to the
frame.
Note: This is best done by 2 persons or with a mechanical hoist.

Pulsation damper

The air pressure in the pulsation damper is preset
at the factory to 2 bar. This covers spray working
pressures between 3 and 15 bar. When using
spray pressures outside this range, the air pres-
sure should be adjusted as shown in the diagram.
The diagram is also embossed on the damper.
