Adjusting Bracket
The brackets that hold the two halves of the frame together are called the four-bolt brackets. The one
at the top of the frame is located inside the beam and has four bolts welded to it. If this top bracket is
not aligned and tightened down properly then the arm will not roll evenly.
SOLUTION STEPS:
1. Loosen all of the four-bolt brackets slightly.
2. Tap the frame gently at the upper four bolt bracket with a rubber mallet to align the halves.
**Using a clamp to hold the two halves of the frame flush, will greatly increase your chances
of success.
