TROUBLESHOOTING
SYMPTOM POSSIBLE CAUSES
TROUBLESHOOTING THE JOINTER - continued
Milled surface grain is rough, raised or fuzzy
1. Lumber has a high moisture content
2. Knives are dull
Milled surface is glossy 1. Cutting depth is too shallow
2. Knives are dull
3. Feed rate is too slow
SOLUTIONS
1. Reduce the moisture content by drying it, or switch to other properly seasoned lumber.
2. Replace the knives for new sharp edges.
1. Increase depth of cut slightly.
2. Replace the knives for new sharp edges.
3. Increase feed rate.
TROUBLESHOOTING THE PLANER
Poor feeding of lumber through the planer
1. Drive belt is worn or broken
2. Drive belt tension spring is broken
3. Lumber sticking on planer's table
4. Feed rollers not applying enough pressure on lumber
1. Planer table is not level to the cutterhead
Not planing lumber to a uniform thickness
Board thickness does not match scale markings
Small raised lines are running along the surface
1. Depth of cut scale not set correct
1. Knives are nicked or broken
1. Check and replace as necessary.
2. Check tension and/or replace the spring.
3. Clean the table and apply silicone based lubricant to reduce friction.
4. Adjust the feed roller pressure.
1. Adjust table and/or cutterhead as needed.
1. Adjust scale to match board thickness
Planed surface is torn - also called 'chip out' or
'tear out'
Planed surface grain is rough, raised or fuzzy
Planed surface is glossy
1. Feed rollers not set properly
2. Lumber not supported when fed into or exiting the planer
3. Short boards not butted
1. Cutting against the grain
2. Cut is too deep
3. Knives are dull
1. Lumber has a high moisture content
2. Knives are dull
1. Cutting depth is too shallow
2. Knives are dull
3. Feed rate is too slow
1. Shift knives left & right so nick is not in the same location on all 3 rotating knives.
2. Replace the broken knives.
1. Adjust feed roller height for applying pressure onto lumber to keep flat on table.
2. Support long boards with roller stands.
3. Run boards butt end to end through planer
1. Cut with the grain. For figured woods, take shallow cuts to minimize tear out.
2. Reduce cutting depth to 1/16" or less.
3. Replace the knives for new sharp edges.
1. Reduce the moisture content by drying it, or switch to other properly seasoned lumber.
2. Replace the knives for new sharp edges.
1. Increase depth of cut slightly.
2. Replace the knives for new sharp edges.
3. Increase feed rate.
