Adjustment Of Boom Tilt - Hardi AEON CENTURA DELTA FORCE Instruction Book

Adjustment of Boom Tilt

The unfolded spray boom must be horizontal before starting a spray job. If needed, horizontal adjustment of the boom
wings is possible by adjusting the ram eye on the hydraulic tilt cylinder on both sides of the sprayer.
÷
NOTE! The boom can tilt down to 4 degrees below horizontal level (only if having AutoTerrain installed).
Steps for Adjustment - Boom Width 27-39 Meters
1. Disconnect the ram eye from the inner wing.
μ
ATTENTION! If not replacing the hydraulic cylinder, it is not
necessary to disassemble the ram eye from the boom. Instead,
rotate the piston rod by turning it with a wrench placed just
behind the ram eye.
2. Loosen the counter nut (A) and the grub screw inside. This will unlock the ram eye from the cylinder's piston rod.
3. With a wrench fitted on the flat surfaces on the end of the ram (just behind A), the ram is now turned inwards or
outwards in relation to the cylinder. The direction depends on your need for adjustment.
• Raise the boom wing: Turn the ram inwards.
• Lower the boom wing: Turn the ram outwards.
4. To be able to lock the ram eye to the piston rod after adjustment,
turn the ram eye 1 full round at a time; this will move the ram eye
2 mm sideways.
5. Reconnect the ram eye to the boom parts to check the horizontal
level of the boom wing.
If further adjustment is needed, go back to step 2.
If horizontal alignment is OK, tighten the pin bolt and the counter nut (A).
Adjustment is now completed.
Steps for Adjustment - Boom Width 24 Meters
The procedure is the same as above; however loosen the counter nut (B)
here to adjust the ram eye inwards or outwards by turning it.
