  Poor feeding of lumber in your Jet Planer can be attributed to several factors: * **Inadequate feed roller pressure:** Adjust the feed roller tension. If proper tension cannot be achieved, replace the feed rollers. * **Rough or dirty planer bed:** Clean pitch and residue from the planer bed and wax the table. * **Slipping transmission v-belt:** Tighten the transmission v-belt. * **Clogged feed rollers:** Clear pitch and residue out of the teeth of the feed rollers.

What causes snipe on Jet JJP-12 and how to prevent it?
- M
  Martin HendersonAug 28, 2025
  Snipe, or unwanted indentations at the beginning or end of a board, can occur on your Jet Planer due to several factors. While it can't be entirely eliminated, you can minimize it by: * **Adjusting table rollers:** Ensure rollers are set to the proper height. * **Supporting long boards:** Use extension rollers to adequately support long boards. * **Adjusting feed roller tension:** Make sure the feed roller pressure is even from front to back. * **Sharpening knives:** Dull knives can contribute to snipe, so keep them sharp. * **Butting lumber properly:** Butt each piece of stock end to end as they pass through the planer.

  Fuzzy Grain can occur if you are planing wood with high moisture content. Remove the high moisture content from the wood by drying it. It can also occur if you are using dull knives, so sharpen or replace/rotate the knife inserts.
