CLAMPING

so far that the front of the clamp foot is raised. If tipping occurs, release the pressure of screw (C) th'e minimum necessary on the side that is low to restore to a level position.

CLAMP PRESSURE Adiustments shoul~ be made with no material under the clamp. Both clamp arms must be adiusted at the same time. · 1. Release al I clamping pressure by loosening the nuts (A & B) and then backing off screw (C). Pull Main Switch to "START" and tighten nut (B). 2. Operating Clamp with power 11 0N 11 , check that levers {E) are in alignment when Clamp is in the down position. This alignment is correct when center of pin (D) is 1-3/ 4 11 above clamp plate. TO ADJUST: I.Dasen nut (G) and tum piston rod {H) in or out of clevis (F) until this align–
