Troubleshooting
This section covers the most common problems and corrections with this type of machine. If you require
additional machine service not included in this section, please contact Woodstock International Technical
Support at (360) 734-3482 or send e-mail to: tech-support@shopfox.biz. WARNING! DO NOT make any
adjustments until power is disconnected and moving parts have come to a complete stop!
PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
Motor will not start or it
growls on start up.
1. Power supply fuse or circuit
breaker has tripped.
2. Magnetic switch components are
at fault.
3. Start capacitor is at fault.
4. Motor fan cover is dented.
5. Motor is at fault.
1. Make sure machine is connected to properly
designed duct line; inspect circuit for electrical
shorts and repair; replace circuit breaker.
2. Disconnect power, and check/replace magnetic
switch components.
3. Replace start capacitor.
4. Replace motor fan cover (and fan, if damaged).
5. Replace motor.
Motor runs slower than
normal.
1. Poor electrical connection.
2. Low power source voltage.
3. Motor is at fault.
1. Inspect the power supply for loose, corroded, or
overheated electrical connection; repair wiring.
2. Have the power source voltage checked; reduce the
length of the extension cord.
3. Replace motor.
Overload light illuminates
and motor stops.
1. Machine is overloaded. 1. Allow to motor to cool; make sure canister
filters are properly installed and the duct line is
connected. (Note: If machine is not connected to a
properly designed duct line, the load on the motor
is at its greatest and may trip the overload relay).
Loud, repetitious noise, or
excessive vibration coming
from dust collector.
1. Machine is not secure on a flat
surface and wobbles.
2. Impeller fan is damaged and
unbalanced; motor fan cover is
damaged.
3. The motor mount is loose.
4. Impeller is loose on the motor
shaft.
1. Stabilize and secure the machine to a flat surface.
2. Replace fan/motor fan cover.
3. Re-tighten all fasteners on the dust collector.
4. Re-tighten; replace the motor and impeller as a set
if the motor shaft or impeller hub is damaged.
Dust collector does not
adequately collect dust or
chips; poor performance.
1. Collection bag(s) full.
2. Canister filter is dirty.
3. Duct line blockage.
4. Dust collector is too far away from
machine(s), or there are too many
sharp bends in the duct line.
5. Lumber is wet and the debris is
not flowing through the lines.
6. There are leaks in the duct line, or
too many open ports.
7. Not enough open branches at one
time causing a velocity drop in the
main line.
8. Duct lines and ports are
incorrectly sized.
9. Machine dust collection design is
inadequate.
10 Dust collector capacity is too small
for the dust collection system.
1. Empty the collection bag(s).
2. Clean the filter.
3. Remove dust line from dust collector inlet and
unblock the restriction in the duct line. A plumbing
snake may be necessary.
4. Relocate dust collector closer to the point of
suction, and rework duct line without sharp bends.
Refer to System Design on Page 27 for more
solutions.
5. Process lumber with less than 20% moisture
content.
6. Rework duct line to eliminate all leaks. Close dust
ports for lines not being used. Refer to System
Design on Page 27 for more solutions.
7. Open 1 or 2 more blast gates to different branch
lines to allow the velocity in the main line to
increase.
8. Re-install correctly sized ducts and fittings. Refer
to System Design on Page 27 for more solutions.
9. Use a dust collection nozzle on a stand.
10. Install a larger dust collector to power your dust
collection system.
