D. REAR CLAMP WILL NOT
ADJUST
If the cap screws (#37) that hold the rear carriage (#44) to the fence are not tight enough, the car- riage may shift slightly when the jaws are locked. This will loosen the grip of the jaws on the rail and prevent the jaws from staying in adjustment.
Step 1.
Check and adjust the position of the rear carriage so that it extends 1⁄8" past the end cap at the tail of the fence. Figure 32.
Note: to properly tighten the cap screws (#37 and #21), insert the long leg of the 5mm Allen wrench into the hex socket of the cap screw and use an adjustable open end wrench on the short leg of the Allen wrench to tighten.

Step 2.
If the rear clamp still won’t tighten up enough, shift the rear carriage another 1⁄16" past the tail end of the fence and repeat the adjustment procedure.
Step 3.
If the rear clamp will not open up far enough, shift the rear carriage so that it extends only 1⁄16" past the end of the fence and readjust.
Step 4.
If none of the above steps work, it may be nec- essary to check and adjust the length of the tie rod (#20) inside the fence. To proceed, refer to the instructions in Part B of this troubleshooting guide.
E. FENCE DOES NOT MOVE
SMOOTHLY
Possible problem: The fence could be adjusted too close to the tabletop and may be contacting the edge of the table or extension wing.
Solution: If necessary, raise any portion of the rail(s) to eliminate interference.
Possible problem: The hairline indicator may be rubbing on the front rail.
Solution: Check to see if it may be shimmed down too far or tipped forward. Reduce shim stack or if the indicator is tipped, add shims under the back of the clamp to level it out.
Possible problem: The indicator clamp may be rubbing the front rail if it is installed backwards.
Solution: Reverse the indicator clamp if neces- sary.
Possible problem: The adjustment nut or stud (#47
0) in the rear carriage may be rubbing the rear rail in some areas.
Solution: Look carefully underneath the rear car- riage in the areas of rough travel. This problem may be solved by any one of the following steps:
a. Take out a washer between the table and rail in that area. Reducing the distance between the two rails will eliminate the problem.
b. Loosening the spring tension will fix the prob- lem if only the stud (#47) is rubbing.
c. Shift the rear carriage 1⁄16" further towards the back of the fence and readjust clamping pres- sure.
