If the clamp is not parallel with the table:
1. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 6.)
2. Loosen the jam nuts on each end of the clamp connecting rod, (Figure 45). (Note: the left
jam nut has left hand threads.)

rod to align the clamp with the table. Place a long strip of paper under each end of the
clamp. Push the cut buttons and when the clamp contacts the table, attempt to pull the strips
out. The clamp should be adjusted so neither strip pulls out.
4. Retighten the jam nuts securely.
