OPERATIONAL TROUBLESHOOTING TIPS
This Operational Troubleshooting Tips section is designed to assist you in recognizing the
symptom, providing a probable cause and suggested corrective action. The items listed are
based on logical symptoms from our experience as well as that of our users.
A. SYMPTOM – EXCESSIVE AIR BLOWING UP AND OUT OF HOPPER
CORRECTIVE ACTION
* Adjust rubber pad pressure by tightening the three (3) adjustment knobs to provide a
positive seal.
* Inspect rubber sealing pad. It may need to be replaced.
* Check installation of rubber wear pad. Make sure rubber portion is down against top of feed
wheel.
* Top of feed wheel may be worn and needs to be resurfaced or replaced.
* Foreign material may be clamped or lodged between steel feed bowl and wear pad. This
would permit air to blow between the two (2) parts and escape into hopper.
* Agitator not securely tightened.
N O T E
If the above condition is allowed to continue without remedy,
premature failure of the rubber pad or feed bowl will occur
and as a result will create even more noticeable discharge of
air back into the hopper or atmosphere. Do not confuse
pocket exhaust with seal failure. Pocket exhaust is rhythmic
puffing which should not cause material to be blown out of
the hopper.
