Halted Feeding
If the in-feed roll takes stock away from you while feeding, then feeding stops before contacting the
knives, the chipbreaker is probably too low. Or the in-feed roller is not set low enough, or does not have
enough pressure. In a similar situation, the in-feed roll takes the stock, the chipbreakers lift, and stops as
you hear the knives contact the material. In this case the pressure bar is too low. Follow the steps on
pages 12-14 for setting the in-feed roller, chipbreaker, pressure bar and outfeed roller in relation to the
cutterhead.

2. Raise the Chipbreaker or
pressure bar per Figure 11,
page 12
3. Increase pressure on in-feed
or out-feed rollers per Figure
11, page 12
Snipe
1. Incorrect setting for in-feed,
out-feed rollers, pressure bar
or chipbreaker
2. Inadequate support of long

2. Support long boards with
extension rollers
3. Adjust table rollers until
desired results are achieved

Poor feeding of lumber
1. Inadequate feed roll pressure
2. Planer bed dirty
3. V-belts slipping
4. Dirty feed rollers
5. Incorrect setting for in-feed,
out-feed rollers, pressure bar
or chipbreaker
1. Adjust feed roll tension or
lower feed rollers
2. Clean pitch and residue off
table with a non-flammable
solvent
