Adjusting the Tabletop

Follow these steps to set up the tabletop. Once the tabletop is set up correctly, it is unlikely that it
ever need to be adjusted. If the table does for some reason need an adjustment, just skip the first step.

SOLUTION STEPS:

1. Line up the aluminum spine between both halves of the table.

2. Tighten the nuts and bolts that draw the two halves of the table together, but don't completely
tighten them.

3. Check that the tabletops meet evenly by running your fingers across the seam on the top of the
table. If they don't meet perfectly, gently tap the half that is out of alignment with a rubber mallet.

4. Tighten the tabletop nuts down completely once they are level.

3. Adjust 10 x 1/4 screws that hold the tabletop to the frame.

Adjusting the Fence

The fences on the work surface should be in perfect square to act as a reference during the
construction process. The vertical and horizontal fences are held in place with allen head sc
The screws holding the fences in the bottom left of the tables are fixed. The other allen screws are
adjustable.

OLUTION STEPS:

rews.

. Place a truly square piece of wood in the corner of the table against the fences.

2

. Tap or move the fences with a mallet so that they match the wood guide.

3

. Tighten the allen screws, starting with the fixed screws first.

Aligning the Arm

When the machine is set up or reassembled after relocation, the arm must be aligned to ensure proper
operation. This procedure requires two people.

SOLUTION STEPS:

1. If the arm is not already on the table, remove the stop bolt on one end of the top beam and slide the
assembled arm onto the table.

2. Re-insert the stop bolt.

3. Loosen the four bolts in the top bracket that hold the arm in place while someone holds the bottom
bracket firmly in place on the table.

4. Do not loosen the bottom bracket bolts.

5. Adjust the arm in the upper bracket until the desired position is reached.

6. Tighten the bolts in the upper bracket.

7. Test the positioning by rolling the arm along the beam. It should roll smoothly the whole way.

8. This is a trial and error procedure and you may need to repeat steps 3 through 7 until the right
position is found.

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.
