Spray gun

the spray gun is held by the operator during spraying. activation 

of the trigger causes liquid to spray. the spray gun has the follow-

ing user-serviceable parts: the air filter, the liquid filter assembly, the 

nozzle assembly, and the batteries. except for the batteries, which are 

accessed by removing the battery cover, nothing inside the spray gun 

shell is user-serviceable. Do not open the spray gun shell; doing so 

will void the warranty on the spray gun.

Air filter

Note: MBP units manufactured after March 2009 do not require an 

air filter on the spray gun air leader. 
For MBP units manufactured before 2009, there is an in-line air filter is 

located outside the base of the spray gun in the air hose. it filters dirt 

out of the air lines. it’s easy to tell the air Filter from the liquid Filter  

assembly because the air Filter is in a silver-colored casing.  replace-

ment parts for the air filter assembly are available as a kit.  

 

the kit includes a filter, and large and small o-rings.     

 

 

Order using ess part number 231.

NOTE

The Spray Gun 

To clean the air filter:

 

1.  unthread the casing from the cap using a 3/4” wrench on 

 

   both parts.  Be careful not to lose the spring or the air filter  

 

  inside of the casing.

 

2.  Check inside each part for debris.  Clean any dirt out with  

 

  compressed air or warm, soapy water.

 

3.  reassemble the air filter, making sure to put it together as  

 

  shown above.
