SYMPTOM
Snipe
(gouging at
ends of board)
POSSIBLE CAUSE(S)
1. Dull blades
2. Inadequate support of long boards
3. Uneven force on cutterhead
4. Rollercase not level with base
5. Lumber not butted properly
Fuzzy grain
Planing wood with a high moisture content
Torn grain
1. Too heaw a cut
2. Blades cutting against grain
3. Dull blades
Rough raised grain
1. Dull blades
2. Too heaw a cut
3. Moisture content too high
Rollercase not level with planer base
Uneven depth of cut
(side to side)
Rollercase elevation
adjusts with difficulty
Board feeds inside, but
stops moving past the
outfeed roller
Board thickness does
not match thickness
scale or display
1. Sprockets or chain dirty
2. Elevation screws, columns dirty
3. Elevation screws worn
4. Friction between rollercase and covers
5. Rollercase not parallel with planer base
1. Outfeed rollers cannot rotate due to
clogging of chips
2. Too much pressure on the cutterhead
from long workpiece
1. Scale pointer not set correctly
2. Display out of calibration
CORRECTIVE
ACTION
1. Replace blades per instructions. See "Maintenance"
2. Support long boards. See "Avoiding Snipe"
3. Gently push board when board is in contact with
only one feed roller. See "Avoiding Snipe"
4. Adjust rollercase. See "Adjusting Table Level"
5. Butt end to end each piece of stock as boards
pass through planer
Remove high moisture content from wood by drying
1. Review "Depth of Cut"
2. Review "Feeding Work"
3. Replace blades per instructions. See "Maintenance"
1. Replace blades per instructions. See "Maintenance"
2. Review "Depth of Cut"
3. Dry the wood or use dried wood
Rollercase not level. See "Adjusting Table Level"
1. Clean and lubricate sprockets and chain
2. Clean and lubricate elevation screws, columns
3. Replace elevation screws
4. Clean and lubricate
5. Adjust rollercase. See "Adjusting Table Level"
1. Clear the clogging, clean dust collection system.
See "Clean Planer"
2. Use support stands to support workpiece longer
than 24". See "Recommended
Accessories"
1. Adjust scale pointer and tighten securely
2. Calibrate display. See "Calibrating the Digital Display"
Chain jumping
1. Sprockets worn
1. Replace sprockets
