7112 Series Flock Feed
Regular Maintenance
1. Remove accumulated moisture form the air filter by opening the bleed
valve located at the base of the filter bowl.
2. To check the sealing area for an out of parallel condition: with the heat
on, set the timer for one (1) second or less; place a light colored cloth
or paper on the base plate; put a piece of carbon paper, carbon down on
the cloth, and run the machine through a cycle. The carbon paper will
leave a picture of the sealing area on the cloth. THE COLOR
SHOULD BE EVEN. A dark area indicates more pressure in that area
and should be corrected.
If the out of level condition is either in the front or back, the base plate
can be tilted. Loosen the bolt to lower the front and raise the back.
Tighten to raise the front, lower the back.
If it is side to side, it must be corrected with shims placed under the
base plate insulator block.
Light or dark spots within the sealing area will indicate that either of
the plates may be warped. This would require surface grinding by a
machine shop. (Make certain that the vacuum arm does not extend
lower than the electrode.)
3. Lubricate the head assembly guide pin monthly with white grease.
4. Lubricate the feed arm shaft and rack with light oil, a FEW drops
weekly.
5. The Teflon® composition covers on the electrode and base plate must
be changed as frequency of use dictates. They provide a non-stick
surface, which can be wiped clean with a cloth.
6. Check the vacuum filters monthly and clean or replace as required.
