Replacing a drag or tangential head
Required tools
1. Small Phillips Screwdriver (Part # MT9004)
2. Leveling Tools (Part #’s 391-635 and 391-636)
Instructions:
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:
1.
Take the knife holder out of the drag head.
2.
Remove the front cover of the drag head by loosening the two [
three
] screws .
3.
Loosen the flat cable b y pulling the flat cable connector cover up. On both sides of t he
connector cover there is a small protuberance that you can pry up using a screwdriver. Gently
pull the flat cable out of the connector
4.
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:
1.
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.
2.
Put the knife holder into the drag head. [
Put the nose piece into the tangential head
].
Caution:
Make sure the tip of the knife does not protrude.
