Clean Dust-Collector’s Snubber Fittings 
Figure 43 

 

7.15.1

  Continually  high  differential  pressure  can  be 

caused  by  the  tiny  orifice  on  the  back  side  or  the 
snubber being plugged with caked dust. 
 

7.15.2

  Remove  the  tubing  from  the  snubber,  as 

instructed in Section 7.9. 
 

7.15.3

  Remove  the  lower  snubber  from  the  bushing  in 

the dust-collector port. Clean dust from the orifice at the 
backside  of  the  fitting  and  reinstall  the  fitting.  Replace 
the fitting if it is damaged or otherwise faulty. 
 

7.15.4

  Replace the tubing into the snubber fitting.

 

 

7.15.5

  Repeat the process on the upper snubber.

Diaphragm Pulse Valve  

 

 

 

 



 

Before servicing the diaphragm pulse valve or 
pulse timer, lockout and tagout compressed air 
and electrical power, and drain compressed air 
from the pulse reservoir. Failure to do so can 
cause injury from the release of trapped 
compressed air and/or electrical shock.

 

 
7.16.1

  Loosen  the  connector  screw  and  unplug  the 

electrical connector from the timer, as shown in Figure 44. 
 
 

 

 

Figure 44 

 
 

7.16.2

  Remove  the  four  cover  screws  and  remove  the 

cover,  while  keeping  the  diaphragm  in  place  within  the 
body. 

NOTE: Before removing the diaphragm and O-

ring, note the round dimple on the upper left on the 
valve  body  and  the  position  of  the  triangular  shape 
on  the  upper  left  of  the  diaphragm,  as  shown  in 
Figure  45.  When  reinstalling  the  diaphragm,  the 
marks must be aligned as shown. 

 
 

 

 

Figure 45 

 

 
7.16.3

  Reassemble  using  the  new  diaphragm  and  O-

ring  from  the  service  kit,  making  sure  the  diaphragm  is 
correctly  aligned,  as  noted  in  Figures  45  and  46,  and 
that the O-ring is seated into the groove. 
 

 



 

If the diaphragm or O-ring are installed 
incorrectly, it can cause an external leak and 
valve malfunction. 

 

7.16.4

  While  holding  the  diaphragm  and  O-ring  in 

position, place the cover and hold it while tightening the 
four screws enough to hold the cover in place.  
 
 
 
 
 

 

 
 
 

Figure 46 

 
 

7.16.5

  Tighten  the  four  bolts  diagonally  to  secure.  If  a 

torque wrench is available, tighten to 110 to 122 lbf in. 
 

7.16.6

  Reattach the electrical connector to the timer.
