Spring Load for Breakaway Section

The breakaway section at the boom end will move back or forth, if it hits a stationary object, e.g. a pole or a tree, when driving
with an unfolded spray boom. The spring on the outer section of the boom will pull the breakaway back into place, when
the boom is clear of the object. When spraying, the breakaway may also sway a little if driving on uneven ground.
The spring is preloaded from the factory - but adjustment is needed, if:
• the breakaway is continuously swaying a lot due to a bumpy field (tighten the spring).
• the breakaway has become very hard to move by hand, when the sprayer is at a standstill (loosen the spring).
• reattachment is necessary due to replacement of the spring, cable for spring or other parts.
Steps for adjustment:
A. Turn these nuts to adjust the spring.
B. Dimension of preload of the spring. Factory setting is 480 mm. Maximum preload is 550 mm.

WARNING! Risk of squeezing. Keep fingers and clothes away from the spring windings, when adjusting the spring.
