Caution Risk of Injury !
Turn the main switch off.
Set the piping reverser only with the main switch turned off.
Clearance between the cutting and reversing position
The knife brackets 5 and 6 are in the cutting position when cylinder 1
has air (see illustration a).
After the venting of cylinder 1 they move outward in the direction of the
arrow into the reversing position (see illustration b).
In the reversing position the reversing tools 2 and 3 must securely
engage the piping strip when retracting.
The corner incision, however, should not be damaged by the retracting
reversing tools.
With a correct setting the clearance between the cutting and the
reversing position is approx. 25 mm.
The stop screws 4 and 7 determine the position of the reversing tools
in the reversing position.
–
Correct the reversing position of the knife brackets 5 and 6 by
turning the stop screws 4 and 7 in or out.
