Adjusting The Spray Boom Transport PositionThe transport height of the spray boom and upward angle can be adjusted in order to prevent interference between the tractor cab and the spray boom during transport. The steel cables (A) (left and right) between the spray boom arms (A) and the centre frame can be connected in three different slots, to allow a higher or lower transport position of the spray boom. When the spray boom is folded and supported by the boom support rolls, the steel cables may not be tensioned. Only during the boom folding action, the steel cable may be under tension. When the steel cable connection is changed also the position of the boom supports with rolls should be adjusted. This can be done by means of the retractable boom supports (B) which can be fixed into different slots and are secured with a bolt and nut.
It could be necessary to adjust also the position of the support rod (C) on the spray boom. The support rods are fixed to the spray boom arms with two brackets. The telescopic transport lock (D) of the parallelogram height adjustment can be fixed in different positions, to determine the rear height and angle of the spray boom arms when folded in. If the transport lock is free the position of the hook can be adjusted and fixed with two bolts and nuts for each side. |

CAUTION:
The lowest position of the retractable boom supports can only be used with 824 sprayers. This position may not be used with 832 and 840 sprayers, since otherwise damage to the liquid level indicator tube could occur.
