A. TABLE CLEARANCE
It is important to minimize the gap between the bottom of the fence and the table so thin material will not slide under the fence during operation. This clearance must be uniform along the table surface. It is also very important that the fence does not contact the table surface when sliding from side to side.
With the fence mounted on the rails, try sliding it over the table. Make sure the fence is supported by all three rollers. Gauge the gap under the fence at various locations over the table surface. There should be a uniform gap of 1⁄16" between the bot- tom of the fence and the tabletop. If the gap is not uniform, loosen the rail mounting bolts and raise or lower one end of one or both rails to achieve a uniform gap.
If ripping thin laminates or veneers, clamp an auxiliary fence to the Shop Fox® Fence so it rests right on the table. This will ensure that thin mate- rial will not slip under the fence.
B. TRACKING
The spring tension on the rear roller will affect the ease with which the fence will travel from side to side. Too much spring tension will restrict free movement of the fence on the rails. Too little tension may allow the fence to derail if moved abruptly or allow the fence to skew slightly when being locked down. Tension is easily adjusted by reaching underneath the rear carriage (#44) and turning the adjustment nut (#48). Figure 10. Tightening the adjustment nut onto the stud will
increase the spring tension while loosening the adjustment nut will reduce the tension. To adjust tracking:

Step 1.
Test ease of movement relative to tracking qual- ity. The best way to do this is to experiment with the rear roller tension until a setting is found that allows comfortable motion and tracking. Grab the fence by the handle and abruptly slide it back and forth several times. When changing direction, both front rollers should stay engaged to the rails. If either roller tends to move away from the rail, increase the rear spring tension and repeat the test.
Step 2.
Continue to increase or decrease rear spring tension as necessary until all rollers remain in constant contact with the rails when changing directions. Don't increase tension to the point that movement becomes restricted.
