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 heavy a cut
2. Blades cutting against grain
3. Dull blades
Rough raised grain 1. Dull blades
2. Too heavy a cut
3. Moisture content too high
Rollercase not level with planer baseUneven 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
2. Chain worn 2. Replace chain
Planer will not operate 1. No power to planer 1. Check power source by qualified electrician
2. Motor overload protection tripped 2. Turn planer off. Reset motor overload protection.
See "Overload Reset"
3. Defective or loose switch or wiring 3. Check switch and wiring by qualified electrician
Belt slipping Loose belt Replace belt, see "Replacing Drive Belts"
Rollercase cannot Workpiece thickness gauge setting Reset thickness gauge setting, see
be lowered restricts rollercase movements "Workpiece Thickness Gauge"
Excessive dust in air 1. Leaking bag or hose connection 1. Check collector bag connections. Check collector
(gouging at ends of hose connections
board) 2. Collector bag leaks 2. Dust trapped under bag clamp or collector bag not
sealed on flange
Excessive fan noise 1. Large debris or piece of wood in 1. Turn planer off and let debris settle in collector bag.
fan housing Remove blade guard and clear chamber
2. Loose fan 2. Open blade cover and tighten fan bolt
Motor overheats 1. Motor overload 1. Reduce depth of cut
2. improper motor cooling 2. Clean sawdust from motor
Tripping circuit 1. Motor overload 1. Reduce depth of cut
breaker or fuses 2. improper capacity of circuit breaker 2. Use proper capacity circuit breaker or fuse
or fuses
3. Dull blades 3. Replace blades
