Motor & Electrical (Continued)
Symptom
Possible Cause
Possible Solution
Machine has
vibration or noisy
operation.
1. Motor(s) or components loose.
2. Belt(s) loose or worn.
3. Motor fan(s) rubbing on fan cover.
4. Pulley loose.
5. Machine incorrectly mounted.
6. Motor bearings at fault.
7. Flush trimmer knives at fault.
8. Spindle/arbor bearings at fault.
9. Centrifugal switch is at fault.
10. Motor shaft bent.
1. Inspect/replace damaged bolts/nuts, and retighten
with thread locking fluid.
2. Tension/replace belt (
Page 56).
3. Fix/replace fan cover(s); replace loose/damaged
fan(s).
4. Re-align/replace shaft, pulley set screw, and key.
5. Tighten mounting bolts; relocate/shim machine.
6. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
7. Resharpen/replace knives; set knife alignment/
height correctly (
Page 52).
8. Test by rotating spindle/arbor; rotational grinding/
loose shaft requires bearing replacement.
9. Replace.
10. Test with dial indicator and replace motor.

Symptom
Possible Cause
Possible Solution
Glue spindle does
not rotate.
1. Motor does not run.
2. Too much grease added to glue spindle.
3. Gear connection shaft stripped/broken.
4. Gear connection shaft stuck.
1. Refer to
Page 46.
2. Loosen pressure-relief set screw.
3. Inspect/replace gear connection shaft.
4. Adjust motor reducer connection plate.
Glue spindle does
not dispense
enough glue.
1. Glue flow out of adjustment.
2. Glue not fully melted, temperature setting
too low.
3. Glue spindle not making full contact with
workpiece.
4. Glue not fully melted, heater rods not
working correctly.
5. Obstruction in glue shaft.
6. Burnt glue in glue spindle.
7. Glue pot thermometer not accurate.
1. Adjust glue flow (
Page 51).
2. Adjust glue pot temperature according to glue
manufacturer's directions; confirm glue temperature
using laser thermometer.
3. Adjust glue spindle (
Page 36).
4. Inspect heater rod connections; tighten if necessary.
Test heater rod amperage (top: 315W, 1.0A; lower
large: 250W, 0.9A; lower small: 160W, 0.6A);
replace if necessary.
5. Remove obstruction from glue shaft.
6. Remove burnt glue from glue spindle.
7. Inspect thermocouple connections and wires for
damage/wear; repair/replace if necessary.
Glue not fully melted
in glue pot.
1. Glue pot still heating.
2. Glue pot temperature is set too low.
3. Heater rods at fault.
1. Wait until glue reaches working temperature.
2. Adjust glue pot temperature according to glue
manufacturer's directions; confirm glue temperature
using laser thermometer.
3. Inspect heater rod connections; tighten if necessary.
Test heater rod amperage (top: 315W, 1.0A; lower
large: 250W, 0.9A; lower small: 160W, 0.6A);
