Mechanical Troubleshooting
Problem Corrective Action
1)
Loud knocking sound
A. Check scalping augers or airlock for objects and remove.
B. Check chains for proper alignment and tension.
C. Check for bent or misaligned auger/shredder fingers.
2) Poor output or uneven flow
A. Gradually increase blower air and/or reduce fiber feed until condition improves.
B. Check hose for blockage. Clean out by turning blowers on high with feed turned off (air only). Hold hand over
output of hose, forcing pressure to increase and expand hose. Repeat this procedure several times until blockage
is removed.
C. Check all hose connections. Tighten hose clamps to eliminate air leakage.
D. Check for damaged airlock seals or bent plates inside the
airlock. Remove hopper and inspect airlock. (See previous section for replacement of airlock seals.)
3) Excessive dust /open blow
A. Reduce air into system by decreasing blower control setting and / or opening slide-gate.
B. Increase hose dia. at end of blowing hose.
C. Use an internal wetting system (IWS).
4) Cold temperature start-up
A. Turn blowers on high, while holding hand over output hose for several minutes. This will allow the airlock
chamber and seals to heat up, reducing the possibility of tripping the motor overload.
Electrical Troubleshooting
Important!! Use proper ‘lock-out tag-out’ procedures at the main power supply before
inspecting or adjusting unit. Consult qualified electrician to answer questions before
attempting to inspect, repair, and operating; or injury may result.
Before operating machine check ‘voltmeter’ for proper voltage and pull ‘red’ kill switch
button out.
Cold temperature operation. Turn blowers on high, hold hand over output to partially
block output and create heat. After 5 minutes, airlock seals should be softening to allow start-
up w/o tripping reset.
1) Voltmeter indicating no or low voltage
A. Check power source for proper voltage.
B. Check input cord(s) for proper connection to power source.
C. Open Main Control Panel and check voltage with multi-tester at the voltmeter terminals. Replace if necessary.
2) Machine does not function with Remote Hand Pendant.
A. Turn machine on manually at machine with ‘toggle switch’ selector. If machine does not run, the remote cord
may be OK. Check power source.
B. Remote control cord is properly plugged in.
C. Check remote cord plug and hand pendant for damage or loose connections.
D. Check transformer breaker with continuity tester.
3) Blower motor not running, but auger motor is running.
A. Check
operation with both the remote cord and manually with ’toggle’ switch on the main Panel Box.
B. Check blower speed control for ‘ON’ position.
C. Check blower breakers inside panel box.
D. Check for defective, broken, or loose wiring connections inside panel box, blower box, and at the external plug
connection.
E. Unplug external plugs centered on lower base of machine below the panel box and slide gate. Plug directly into
extension cord with 120 volt power. This will verify the blowers are OK.
F. If blower control(s) are faulty, by-pass the blower control by removing the wires at connection on back of panel
box and joining the two wires. This will offer on/off control of the blower; but blower will run full speed only.
G. Visually inspect and/or replace blower relay inside Main Control Panel.
