ADDING A MANDREL SET A mandrel set (including storage bracket and pressure plate) is not supplied with the press but is available as Clarke part no 7615062. 1. Bolt the mandrel storage bracket to the side of the frame using the bolts supplied.
PREPARATION FOR USE 1. Insert the pump handle into the pump actuating lever. 2. Purge any air from the system by opening the release valve (turning the control knob anti- clockwise) and pumping several full strokes to eliminate any air bubbles.
FITTING THE MANDRELS If a set of mandrels is available, any one may be connected to the end of the ram using the adaptor supplied. Alternatively, the basic pressure cap can be fitted as shown. Secure the pressure cap by tightening the grub screw with a suitable hexagonal key.
OPERATION 1. Place the workpiece on the bed. It must be completely stable and supported by packing or shims where required. Steel pressing plates are supplied, which locate on the bed. Place the workpiece on a combination of these to give it stability. CAUTION: DO NOT POINT LOAD THESE ACCESSORIES AS THEY ARE NOT DESIGNED TO TAKE THE FULL FORCE OF THE RAM IN ONE SPOT.
Oil should be level with the bottom of the hole. If necessary top up with CLARKE hydraulic oil, Part No. 3050830. This task is carried out with the ram fully retracted.
