FEEDING PROBLEMS
Make sure that power is disconnected before inspecting machine!
SYMPTOM
SOLUTION
The stock stops but the feed-rollers
continue to turn.
This is a traction or friction problem.
1) Make sure your stock is not binding
in the guides.
2) Make sure the stock is of consistent
width. Saw ripping is inadequate.
3) Make sure stock is the proper width
for the knife profile.
4) Make sure the head is set at the
correct height.
5) Check the rollers for wear or pitch.
6) Check your pressure screw pressure.
7) Check the base or bed for rust or
scars.
One roller stops while the other
continues to operate.
Check for a loose set screw on one of the
two chain sprockets involved with the
roller that won’t operate.
Both feed rollers turn until you try to
engage stock and then both stop.
Check for a broken roll pin in the P-108
bronze gear, P-504 assembly. Check the
pin with a paper clip wire. If the wire will
not go in one end of the pin and out the
other, the pin is broken. The pin is a 1/8”
diameter spring tension roll pin 5/8”
long.
Neither feed roller will turn even in the
absence of stock.
1. Check for a broken fiber drive, P117.
2. Check for a broken primary shaft,
P203.
3. Check for a stripped small bronze
worm gear, P105, inside the gear box.
