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.
