The Operating Mode Switch has two positions - NORMAL and INCH. With
the switch set to INCH all work stations are in the slow speed Inching Mode.
3.10.1 Inching Positon
In Inching position the arm will travel down slowly when footswitch is fully depressed. The
arm will remain in any position when foot is removed. Turn switch to NORMAL to return
arm to top of stroke. All tool setting and adjusting and setting of stroke limit switches should
be done in the Inching position.
3.10.2 Normal Operating
With Selector Switch to NORMAL the arm will travel down at operating speed when
footswitch is fully depressed and will return to top of stroke when foot is completely removed.
The footswitch does however have three “positions” giving the very useful facility that after
bringing the arm down by full depression of switch, the arm may be held in any position of the
stroke by raising the foot to the mid-position. Remove foot and arm will return to top position.
3.10.3 Punch and Die Alignment
Should be checked before using, and MUST be checked after punch and die changes have
been made.
To check alignment switch mode of operation INCH, then inch the punch
down by fully depressing the footswitch. Care must be taken as the punch
approaches the die, if misalignment is apparent remove foot from switch.
To align punch and die release bolster fixing screws, operate the foot switch with care,
aligning the bolster containing the die to the punch, the punch will stay in the down position.
Centralise the die clearance around the punch, clamp the bolster in position, tighten die
retaining screw, check die maintains in the central position after clamping. Return punch to
top position by switching back to run position.
