6. Drawbar Adjustment

To perform the adjustment the Foam Dusk Cap must be removed. We also recommend that
the Drawbar is adjusted while the 704 Series 2 is standing up. This is to ensure the correct
positioning of the Mid Unit on the Drawbar.
The Mid Unit should be positioned centrally and flush with the cabinet edges.
To do this you require Tool 1.3 – HH15121 MF Removal Tool and Tool 1.1 – HH15148 Screw-
driver 4mm x 100mm.
Tool 1.3 – HH15121 MF Removal Tool is
used to tighten and loosen the nut
which holds the Mid Unit on the Draw-
bar.
Adjusting this tightens the Mid Unit to
the Drawbar
Tool 1.1 – HH15148 Screwdriver 4mm x
100mm is used to turn the drawbar
which decreases and increases the ten-
sion on the spring at the back of the
Drawbar. Turning this moves the Mid
Unit in/ out of the cabinet.
