tightening the jam nut snug against the face of the tack weld block.

XIAL FEED
3.4.1 Selecting the feed direction
The feed direction has three positions:
• Forward
• Neutral
• Reverse
Pushing the three-position feed shaft in on one side or the other will feed in the
direction indicated by the arrow on that side of the body. Check that the engage-
ment pins are fully engaged. The neutral (middle) position is for no feed.
A shaft under load may require a firm bump to disengage.
If the axial feed box fails to feed the tool head, check the shear pins. Replacement
pins are included with the AFU. To replace a pin, see Section 5.3.1 on page 59.
CAUTION
Feeding the bar into a fixed object could damage the internal feed
clutches.
