DynamicCenter cable adjustment

Before beginning adjustment, the sprayer must be placed on level ground with boom unfolded and in level position.
1. Loosen jam nut (A) and slacken the spring at the nut (B).
2. Position the lever (C) with the cylinder into vertical position.
3. Tighten the horizontal spring without tensioning it.
4. Adjust the bolts (D) to tighten the two cables equally.
5. No further tightening of the spring required. But when driving in
hilly terrain with high speed, you may tighten the nut (B) another
3/4" (20 mm).

Wing tilt adjustment

÷
Note: This adjustment is only relevant for sprayers with DynamicCenter.
The horizontal adjustment of the wings is done by the tilt cylinder. The
boom must be unfolded and tilted completely down to horizontal
position. If necessary, adjust the wing as follows:
1. Support the boom on jack stands to relieve the load from the
hydraulic cylinder.
2. Loosen set screw (A).
3. With a 27mm wrench on key profile (B) at end of the ram, adjust
the cylinder ram to get the desired wing level.
4. Tighten the set screw (A) again.
5. Repeat steps for the other side.

Pendulum lock adjustment

Pendulum lock adjustment is necessary if there is slack in the chains or
the lock cylinder will not fully retract. Before adjustment, sprayer should
be parked on level ground and the pendulum lock engaged.
1. Loosen nuts (B) and adjust chain slack with locknuts (A).
2. When chain slack is removed (with lock cylinder still fully retracted),
tighten nuts (B).
3. Check lock operation. If cylinder will not fully retract, loosen chains
equally until it will.
÷
Note: Adjust both sides equally.
÷
Note: Prevent turnbuckles from turning while adjusting nuts (A) & (B). Do not twist chains.
