Model G0841 (Mfd. Since 06/18)
-57-
Symptom Possible Cause Possible Solution
Machine stalls or is
underpowered. 1. Workpiece material not suitable.
2. Feed rate too fast.
3. Excessive depth of cut.
4. Workpiece excessively bowed.
5. Dull inserts.
6. V-Belts slipping or pulleys misaligned.
7. Dust collection problem.
8. Dust collector undersized.
9. Motor(s) overheated.
10. Pulley/sprocket slipping on shaft.
11. Start delay module at fault.
12. Motor(s) bearings at fault.
1. Only cut wood/ensure moisture is below 20%.
2. Reduce feed rate.
3. Reduce depth of cut. (Hardwoods require a
shallower depth of cut than soft woods.)
4. Only plane suitable workpieces (
Page 34).
5. Rotate/replace inserts ( Page 42).
6. Tension/replace V-belts (
Page 59); ensure pulleys
are aligned ( Page 62).
7. Clear blockages, seal leaks, use smooth wall duct,
eliminate bends, close other branches.
8. Move closer to machine /redesign ducting layout/
upgrade dust collector.
9. Let motor(s) cool; reduce workload.
10. Tighten/replace loose pulley/sprocket/shaft
11. Test/repair/replace.
12. Test/repair/replace.
Machine has
vibration or noisy
operation. 1. Motor, motor mount, or components loose.
2. V-belts worn, loose, or pulleys misaligned.
3. V-belts slapping guard(s).
4. Pulley(s) loose.
5. Chain drive access door not fully closed.
6. Chain drive off track.
7. Machine incorrectly resting on floor.
8. Motor fan(s) rubbing on fan cover(s).
9. Dull inserts.
10. Cutterhead(s) bearings at fault.
11. Motor(s) bearings at fault.
12. Feed system gearbox at fault.
1. Re-tighten component; inspect/replace damaged
bolts/nuts.
2. Tension/replace V-belts ( Page 59); ensure pulleys
are aligned (
Page 62).
3. Tension V-belts ( Page 59); position and secure
guards so V-belts will not contact.
4. Ensure pulleys are aligned ( Page 62);replace shaft,
pulley, set screw, and key.
5. Ensure access door is closed and latched.
6. Ensure chain is properly seated on sprockets.
7. Level machine (
Page 24).
8. Fix/replace fan cover(s); replace damaged fan(s).
9. Rotate/replace inserts (
Page 42).
10. Replace bearings/align cutterhead(s) (
Page 64).
11. Replace bearings/align pulley(s) ( Page 62).
12. Rebuild gearbox to replace bad gear(s)/bearing(s).
Motor & Electrical (continued)
Operations
Symptom Possible Cause Possible Solution
Workpiece stops/
slows before
reaching upper
cutterhead. 1. Lower cutterhead removing too much
material.
2. Resin build-up on planer components.
3. Idler roller and/or serrated roller too high.
1. Raise infeed table height to reduce lower cutterhead
depth of cut.
2. Clean planer components with a resin dissolving
solvent ( Page 49).
3. Check/adjust idler roller (
Page 71) and/or serrated
roller ( Page 72) height.
Finished workpiece
not matching
entered workpiece
thickness value. 1. Lower cutterhead removing too much
material.
2. Slack in elevation chain.
3. Digital controls and headstock height not
synchronized.
1. Raise infeed table height to reduce lower cutterhead
depth of cut.
2. Increase elevation chain tension (
Page 77).
3. Reset headstock height ( Page 70).
