A.1 – Recommended Maintenance items
Hi- cap “N” stoner are designed to give years of trouble-free service. However,

The following is a list of some areas that can be problems, if not periodically checked.
A.1.1 – The Deck

deck and will eventually plug the deck completely (blinded deck). When the deck
becomes plugged, it will be necessary to remove it from the machine and thoroughly
clean it. A deck that is only partially cleaned will become plugged sooner. To check if
a deck is clean, place a light on a drop cord under the deck. If the deck is clean, you
should be able to see light through every opening of the deck cover. Dirty areas will
show up as dark spots and should be cleaned more thoroughly.
