CLAMPING

Raising and lowering of the Clamp is hydraulically powered and electrically operated by manually actuating the pedal. With Main Switch pulled out to II START II and control panel switches set for desired operating procedure, hydraulic oil flows from pump through· the Clamping Valve Block to the bottom of Clamping Cylinders, pushing pistons

up, which in turn causes Clamp to move to its down position. When the pedal is partly depressed, the Clamping Circuit activates the Clamping Sole-· noid. This causes the plunger in Clamping Valve Block to shift the flow of oil to the top of Clamp- .ing Cylinders, pushing pistons down which in turn causes Clamp to rise to its up position.

MAINTENANCE AND ADJUSTMENTS

CLAMPING SPEED Clamping speed is adiusted by varying the flow of hydraulic oil to the Clamping Cylinders by means of the Clamping Speed Metering Screw. TO ADJUST: To slow clamping action, turn Clamping Speed Metering Screw in (clockwise). Tuming metering screw out· (counterclockwise) will produce a faster clamping action. ·
