A.1.4 – Air Filters
The Hi- cap “N” stoner come equipped with air filters on the side of the blower frames,
they are designed to screen dirt out of the air before it enters the machine. If they
become plugged, the fans cannot pull enough air through them to provide proper
stratification. The air filters can be cleaned by removing them from the machine and
gently tapping them on them, or a more effective cleaning may be obtained by
removing the filters and using compressed air to blow out the dirt. If you must clean
filters while the machine is running use an industrial vacuum cleaner and vacuum the
dirt from the filter surface.
A.2 – Basic Troubleshooting
Most operators of Hi-cap stoner can get acceptable separation after working
with the machine for a few minutes. However, many operators expect results too soon
from their stoners. When an adjustment is made, wait at least couple of minutes
before deciding whether it has made any improvement. A certain amount of time is
required for the entire deck surface to adjust to the new conditions. From
conversation with customers over a period of years, we have compiled a list of
problems most generally encountered with an operation of stoner.
A.2.1 – Blinded Deck
If there is insufficient air and the fans are running correctly, it could be that the deck
needs cleaning. The deck can be cleaned best by blowing the dirt and chaff out from
the top downward, while the dryer is running.
A.2.2 - Dirty Air Filters/Obstructed Airflow
If there is insufficient air and the fans are running correctly, it could also be that the
air filters surrounding the mainframe have become plugged and are not allowing
enough airflow to achieve product stratification.
