Adjust the Power Drawbar

If you have not yet done so, you must adjust the Power Drawbar. Complete the following steps in the order listed:

Adjust the Drawbar Tension

About Drawbar Tension
Adjust the Initial Setup
Adjust the Drawbar Tension
This adjustment sets the highest possible drawbar tension while still allowing the Power Drawbar cylinder to
release the tool. For information, see "About Drawbar Tension" (on the next page).
NOTICE! After the initial installation, you must examine the drawbar tension weekly. During periods of heavy
use, examine the drawbar tension more frequently. If you don't, there's a risk of tool pull-out.
To adjust the drawbar tension:
1. Put an empty Tormach Tooling System (TTS) tool holder into the collet.
2. While using one hand to support the tool holder, use the other to push the Release Tool button.
