OPERATING PROCEDURES

WARNING: Do not attempt to unclog (back flush) the spray gun 

by squeezing the trigger while holding your finger in front of  

the fluid nozzle.

CAUTION: Pressure may vary according to viscosity of material 

used. Maximum working pressure of the gun is 60 PSI. Do not 

exceed pressure  limit of gun or any other component in system!

CAUTION: Prior to daily operation, make certain that all 

connections and fittings are secure. Check hose and all  

connections for a weak or worn condition that could render system 

unsafe. All replacement components such as hose or fittings must 

have a working pressure equal to or greater than system pressure.

Prior to shipment, this spray gun was treated with an anticorrosive 

agent. Before use, make sure that it is carefully flushed with thinner.

1. Loosen the 

air cap (c) and rotate the horns (D) to achieve

the desired spray pattern. Tighten the 

air cap.

2. Attach 

spray gun cup (a) to the gun handle.

noTe: The (B) filter supplied is optional to protect against

contaminants and small particles. See parts list for

filter orientation.

CAUTION: do not use latex or other heavy paints

3. Attach air supply line to 1/4" NPS air inlet.

CAUTION:  NEVER  point  spray  gun  at  self  or  any  other  person. 

Accidental discharge of material may result in serious injury. 
4. Adjust air pressure on the air compressor.

CAUTION: DO NOT exceed 60 PSI.

5. Depress the 

spray gun trigger (e) fully to spray material.

noTe: Depressing the trigger partially will cause only air

to be released.

ADJUST SPRAY GUN:

1. Turn the 

fluid control knob (I) counterclockwise to increase

the amount of  material released, or clockwise to decrease.

2. Turn the 

pattern control knob (h) counterclockwise to

increase the width of the “fan spray”, or clockwise to decrease

the width of the spray.

3. Turn the 

air volume control knob (F) counterclockwise

to increase the air quantity, or clockwise to decrease

the air flow.

CAUTION:

 

Care should be exercised when handling spray gun

to avoid damage to the orifice of the air cap and tip of fluid nozzle. 

Damage to these parts results in irregular spray patterns.   

MAINTENANCE

WARNING: Shut off air compressor, release all pressure 

by depressing trigger, and disconnect power source before 

disassembly or removal of any part of the gun or attached  

components.  

CAUTION: Always exercise extreme care when using any solvent 

or thinner. Never clean the gun near fire, flame, or any source of heat 

or sparks. Properly dispose of used cleaning materials.

CAUTION: DO NOT soak the entire spray gun in solvent or  

thinner for a long period of time as this will destroy lubricants  

and possibly impair operation. NEVER use lye or caustic alkaline 

solution for cleaning. Such solutions will attack aluminum alloy  

parts of the gun.
