USAGE INSTRUCTIONS (Round Hole)
STEP 1
Drill a φ13mm (MIN) pilot hole with a drill bit.
STEP 2
Switch the impact driver to the reverse position, extend the bolt to the longest length UNTIL IT MAKES A RATTLING SOUND.
Warming: STRICTLY PROHIBIT INSTALL THE MOLD FOR PUNCH WHEN THE DRIVING BOLT IS NOT FULLY EXTENDED!!
STEP 3
Fit the required size of die onto the bolt and insert the bolt into the pilot hole.
Thread the set nut onto the bolt and hand-tighten it
UNTIL SNUG.
Warming: STRICTLY PROHIBIT INSTALL THE MOLD FOR PUNCH WHEN THE DRIVING BOLT IS NOT FULLY EXTENDED!!
STEP 4
Turn the bolt with an impact driver; this pulls the punch toward the die. Keep turning until the punch passing through the material.
(Suggestion: Work with 14.4V or the higher voltage impact driver, Torque range 120~150Nm)
STEP 5
Separate the bolt and punch and remove the little ring of waste material inside the die.
**When idling occurs during punching, STOP the operation immediately and exclude the following conditions, which may cause idling:
(A) Whether the workpiece within the cutting capacity
(B) Whether the punch die/cutting surface wore
(C) Whether the punch die, bolt and set nut fit in the correct position
(D) The power tool is out of power or the torque is less than 110Nm
