2. INSTRUCTIONS FOR USE
2.1) Setting
– Consult the table in Fig. 5 to select the RD... Punching Kit suitable for the hole to be made..
– Screw the punch directly onto the appropriate thread of the stud (B or C).
Tighten by hand, do not over-tighten (see Fig. 1a).
• Punch sizes ø 15.5 - 30.5 mm have a 7/16"-20 UNF thread (stud C).
• Punch sizes ø 31.8 - 47.2 mm have a 3/4"-16 UNF thread (stud B).
– Insert the appropriate locking screw (B or C) completely into the die and screw the "die-locking
screw" assembly into the upper die holder (see Fig 1b).
Use the 4mm allen key, supplied with the tool, to tighten the locking screw.
NOTE: turn the locking screw, anticlockwise to secure and clockwise to release.
2.2) Punching
– Position the tool on the trunking, at the desired hole centre (see Fig. 2). Turn the handle (9) clock-
wise until the hole is produced. Turn the handle anti-clockwise to release the punch, the extractors
(22) will then permit the tool to be disengaged from the trunking.
– Ensure that no punch slugs remain in the die. To remove a slug from the die, insert a small drift
through the locking screw (B or C), on to the slug and tap sharply.
NOTE: when punching holes in the base of trunking (see Fig. 3) with sides 50 mm (2") high, it is
necessary to fit the die after positioning the tool on the trunking.
Prior to removing the tool from the trunking, unscrew and remove the die.
