REPLACING A DRAG HEAD OR A TANGENTIAL HEAD
Below is the description for the replacement of a standard drag head. The procedure described is
also roughly applicable to the replacement of a tangential head. The areas where the replacement
procedure for the tangential head differs are indicated between brackets and in italics.
The only major difference between replacing a drag knife and a tangential knife is the positioning of
the screws on the carriage plate.
To remove the drag head, proceed as follows:
65.Take the knife holder out of the drag head.
66.Remove the front cover of the drag head by loosening the two (three) screws .
67.Loosen the flat cable by pulling the flat cable connector cover up. On both sides of the connector
cover there is a small protuberance that you can pry up using a screwdriver. Gently pull the flat
cable out of the connector
68.Remove the drag head. To do this, loosen the three screws with two counterclockwise rotations
using a small diameter screw driver and lift the head upwards to remove it from the screws.
To re-install the drag head, proceed as follows:
69.Place the head back onto the screws. Tighten the screws with a 1 1/2 clockwise rotation. Do not
tighten them firmly because the height and position of the head still need to be adjusted.
70.Put the knife holder into the drag head. (Put the nose piece into the tangential head).

51.
Caution:
52.
Make sure the tip of the knife does not protrude.
72.
73.Secure the knife holder.
74.
53.
Note:
54.
This only applies to the re-installation of a drag head.
75.
76.Adjust the height and position of the head.
77.
78.The standard operating procedure for doing this is described in the SummaSign Upgrade Kit
(p/n 391-950).
55.
Note:
56.
The operating procedure described in the Upgrade Kit applies to a tangential
head. However, the procedure to be followed for a drag head is roughly applicable.
