Why is my Jet JJP-12 Planer leaving a rounded, glossy surface?
A rounded, glossy surface from the Jet Planer can result from: * Dull knives. Sharpen or replace knives/Rotate knife inserts or replace. * Feed speed too slow. Increase speed. * Cutting depth too shallow. Increase depth.
Why is the finished stock concave on the back end after using my Jet JJP-12 Planer?
If the finished stock from your Jet Planer is concave on the back end, it indicates that the knife is higher than the outfeed table. Align the cutterhead knives with the outfeed table.
Why is the finished stock concave on the front end after using my Jet JJP-12?
If the finished stock from your Jet Planer is concave on the front end, it means the outfeed table is higher than the knife. Align the cutterhead knives with the outfeed table.
What causes uneven depth of cut side to side on Jet Planer?
An uneven depth of cut from side to side on the Jet Planer can be due to knife projection or the cutterhead not being level with the bed. Adjust the knife projection or level the bed.
What to do if board thickness doesn't match depth of cut scale on Jet JJP-12?
If the board thickness doesn't match the depth of cut scale on your Jet Planer, the depth of cut scale is incorrect. Adjust the depth of cut scale.
Why is the chain jumping on my Jet JJP-12 Planer?
Chain jumping in the Jet Planer can be caused by inadequate tension, misaligned sprockets, or worn sprockets. Adjust the chain tension, align the sprockets, or replace the sprockets.
Why won't my Jet Planer start or keeps tripping the breaker?
There could be several reasons why your Jet Planer won't start, restarts automatically, repeatedly trips the circuit breaker, or blows fuses: * **No incoming power:** Ensure the unit is properly connected to a power source, the on-button is fully engaged, and the stop-button is disengaged. * **Overload automatic reset:** Allow adequate cooling time for the machine to reset after an overload. If the problem persists, check the amp setting on the motor starter inside the electrical box. * **Planer frequently trips:** Reduce the depth of cut to lighten the load. Also, verify the amp setting on the overload relay matches the full load amps on the motor plate. Check for loose electrical leads. * **Building circuit breaker trips or fuse blows:** Confirm the planer is on a correctly size...
What causes poor feeding of lumber in my Jet JJP-12?
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.
Why does my Jet JJP-12 Planer leave a rounded, glossy surface?
A rounded, glossy surface after using your Jet Planer is typically caused by: * Dull knives: Sharpen or replace the knives. * Feed speed too slow: Increase the feed speed. * Cutting depth too shallow: Increase the cutting depth.
What causes rough or raised grain when using my Jet Planer?
Rough or raised grain when using your Jet Planer can result from: * Dull knives: Sharpen the knives. * Too heavy a cut: Adjust the depth. * High moisture content: Remove high moisture content from wood by drying.
