Symptom
Possible Cause
Possible Solution
Sanding belt
clogs quickly.
1. Sanding belt grit too fine for particular job.
2. Excessive depth of cut.
3. Wood is too moist.
4. Using amp load meter to establish material
removal amount.
1. Replace with coarser grit sanding belt (
Page 35).
2. Reduce depth of cut.
3. Allow wood to dry to below 20% moisture content.
4. Use alternate methods to establish material removal
amount (
Page 34).
Sanding
belt does
not tension
correctly; rollers
slip under belt.
1. Low air pressure.
2. Air leaks in system.
3. Air cylinder shaft worn/damaged.
1. Adjust air pressure to 75 PSI at primary regulator
(
Page 24).
2. Inspect all hoses and connections for leaking air; use
a water/soap mixture on suspected area to detect
bubbles.
3. Repair/replace air cylinder.
Sanding belt
runs off to one
side, stopping
sander.
1. Power connections wired out of phase.
2. Airflow adjustment knob closed.
3. Belt tracking incorrect.
4. Air fork gap/air lines clogged.
5. Solenoid valve/air manifold at fault.
1. Correct phase polarity (
Page 28).
2. Turn valve all the way out, then back in 3
1
⁄
2
" turns.
3. Adjust belt tracking (
Page 48).
4. Clean air fork gap/air lines.
5. Test/repair/replace.
Poor, non-
aggressive
sanding results.
1. Sanding belt worn/clogged.
2. Sanding belt grit too fine for particular job.
1. Clean/replace sanding belt (
Page 35 & 44).
2. Replace with coarser grit.
Sanding belt
will not start,
but conveyor
will.
1. No air pressure to sander.
2. Airflow adjustment valve closed.
3. Limit switches engaged.
4. Sanding belt not tensioned.
1. Connect sander to compressed air system (
Page 63).
2. Open airflow adjustment valve.
3. Center sanding belt so it is not touching limit switches.
4. Tension sanding belt (
Page 35).
Conveyor belt
not tracking in
center.
1. Conveyor belt moved out of adjustment.
1. Adjust conveyor adjustment bolts (
Page 62).
Conveyor belt
slipping.
1. Conveyor belt has incorrect tension.
2. Conveyor rollers contaminated with dirt or
dust.
1. Adjust conveyor belt tension (
Page 62).
2. Clean conveyor rollers.
Emergency
brake stops
slowly.
1. Low air pressure.
2. Air leaks in system.
3. Brake rotor contaminated with oil.
4. Brake pads worn.
1. Adjust incoming air pressure to 75 PSI (
Page 24).
2. Inspect all hoses and connections for leaking air; use
water on suspected area to detect bubbles.
3. Clean brake rotor with automotive brake parts cleaner.
4. Replace brake pads (
Page 52).
Grinding noise
when braking.
1. Brake pads severely worn.
1. Replace brake pads (
Page 52), have rotor turned/
trued by a machine shop. Replace rotor.
Air leaking from
sander.
1. Air release sound is normal.
2. Water filter/trap drain cock left open.
3. Air line ruptured or air leaking at a connection
point.
1. Unless there is clear evidence of an air leak or perfor-
mance issue with belt oscillation or braking time, take
no action. Air release sound is normal.
2. Ensure water filter/trap drain cock is tight.
3. Locate source of sound and determine likely cause
based on visual evidence.
