Breakaway section adjustment

The breakaway is part of the third outer section of the boom and is
designed to breakaway in the event you make contact with something
for example a fence. The breakaway is held in position under spring
tension and if forced is designed to breakaway in three planes as
illustrated.
±
WARNING! If the breakaway hits hard enough it may be damaged
beyond repair.
The progressive breakaway function is adjusted by altering the spring
attachment point on the progressive mechanism.
The turning "half circle" part should be in a rest position as in the
picture. If out of adjustment, the "half circle" part is turned more or
less as in the picture and needs adjustment:
1. Loosen the nut (D) on the fork bolt to slacken the spring.
2. Remove the bolt (A) on the turning progressive mechanism that
holds the breakaway wire.
3. Reposition the bolt into hole (B) or (C) to adjust the "half circle"
rest position.
4. Tighten the nut (D) on the fork bolt until a suitable spring load
is achieved.
μ
ATTENTION! Observe the amount of spring load required
when driving with the sprayer. If the breakaway sections
release too much, the spring load must be increased.
