Installation Installation This spray gun can spray most coatings or fin- ishes currently being used for small compo- nent plastic, wood and metal finishing applications, while easily operating from paint delivery systems, such as pressure pots or remote pumps for production line operation. The air regulator must have a minimum air flow capacity of 30 scfm at 100 psi (0.7 MPa, 7.0 bar) air pressure.
Guns without Manifold The gun is shipped ready for use in a circulat- ing system, with a fitting installed in each fluid port. Connect the fluid supply line to one fluid inlet fitting (15) and the fluid return line to the other.
Installation Mount Gun Reciprocating Arm Rod Mount To mount the gun on a reciprocating arm rod [0.75 in. (19 mm) diameter maximum], insert the bar (A) through the hole in the manifold as shown in F . 3. NOTE: Use the 1/8 in. alignment slot (P) to assist in orienting the gun.
Setup Connect Air Line NOTE: If your regulated air source does not • have a filter, install an air filter (G) on each air line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the appearance of your finished workpiece.

Connect Fluid Hose NOTE: Before connecting the fluid line, blow it • out with air and flush it with solvent. Use solvent that is compatible with the fluid to be sprayed. Install a fluid regulator (L) on the fluid • line to control fluid pressure to the gun.
Setup Flush Spray Gun Before running any paint through the spray gun: 1. Flush the gun with a solvent that is compat- ible with the fluid to be sprayed, using the lowest possible fluid pressure and a grounded metal container. See Clean and Flush Gun, page 20.
Page 17
. 11: Fluid Pressure Regulator NOTE: A larger fluid nozzle at a reduced fluid pressure will maintain the same flow rate, but the fluid stream (velocity) will slow down. When air is applied, the lower velocity allows the air to act on the fluid longer, which improves atomization.
Operation Operation Pressure Relief Procedure 1. Turn off all bleed type air valves and all other air and fluid supplies to the gun. 2. Trigger the gun into a grounded metal waste container to relieve fluid pressure. . 13: Pressure Relief Apply Fluid The gun does not have an air shutoff.
Daily Gun Care NOTICE Methylene chloride with formic or propionic acid is not recommended as a flushing or cleaning solvent with this gun as it will damage aluminum and nylon components. Solvent left in gun air passages could result in a poor quality paint finish. Do not use any cleaning method which may allow solvent into the gun air passages.
Operation General System Maintenance Follow the Pressure Relief Procedure, • page 18. Clean the fluid and air line filters daily. • Check for any fluid leakage from the gun • and fluid hoses. Tighten fittings or replace equipment as needed. Flush the gun before changing colors and •...
Troubleshooting Troubleshooting Problem Spray Pattern Right Spray Pattern Wrong Heavy top or bottom Spray Pattern Wrong Split pattern Spray Pattern Wrong Cause Normal pattern. Dirty or damaged air cap or fluid nozzle. Fan pressure too high for vis- cosity of material being sprayed.

Problem Gun spitting. Will not spray. Excessive air blowing back. Gun fluid pressure is too high with gun triggered (cannot achieve desired flow rate). Using a low fluid pressure set- ting, the fluid flow is too high, making it necessary to restrict needle travel to reduce fluid flow.
Service Service NOTE: Numbers in parenthesis in the text refer to the reference numbers in the figures and in the parts list. Disassembly 1. Follow the Pressure Relief Procedure, page 18. 2. Remove gun for service: a. With Manifold: Use the 4 mm allen wrench supplied to unscrew the two Torque to 155-165 in-lb (18-19 N•m).
6. Use a 1/16 hex wrench to loosen the fluid needle set screw (7a). Remove the needle (6) from the piston (7). 7. Check the fluid needle (6) for damage or excessive wear. Replace the needle if nec- essary. NOTICE The needle and tip are permanently bonded.

Air Flow Air Flow See the chart to determine air consumption. Add the air consumption values shown for the atom- izing air and fan air to get the total air consumption. For example, air cap 24C182 with 35 psi inlet pressure uses 3.9 scfm atomizing air and 5.4 scfm fan air for a total of 9.3 scfm air consumption.
