Spray Guns
Operation
1. Connect air supply hose at handle of gun.
2. Connect a pressurized fluid supply or paint siphon cup to the gun fluid inlet.
3. Fluid flow can be controlled using the fluid control knob, this restricts flow by limiting needle travel. It is best to control
fluid flow by proper selection of fluid orifice size and use the fluid control knob to “fine tune flow rate”.
4. Fan width can be adjusted using the fan control knob. Turning the knob clockwise narrows the fan.
Maintenance
IMPORTANT! Routine cleaning and maintenance is essential to insure proper gun operation.
Several states prohibit spraying solvent into the atmosphere and require the use of covered gun cleaner.
1. If a gun cleaner is being used, connect and clean the gun in the gun cleaner according to the manufactures
instructions.
2. If a gun cleaner is not being used:
Remove air cap and clean separately using clean solvent.
For pressure setups, connect a pressurized solvent supply to the fluid inlet, trigger the gun allowing solvent to flow
thru the gun until clean.
For siphon setups, first clean the siphon cup thoroughly then spray clean solvent thru the gun until clean.
NOTE: Gun head disassembly is not recommended for normal cleaning and maintenance.
Gun head disassembly and reassembly instructions:
Have repair kit # 10-110 available before gun disassembly.
Gun head disassembly
To remove the nozzle carrier (4) and air cap adapter (6):
1. Remove the air cap (1), swirl insert (2), fluid nozzle body (3), and needle (13).
2. Remove the needle seal cartridge (27).
3. Loosen the locknut (25) and remove fluid inlet (24) using a 5/8” open-end wrench.
4. The nozzle carrier (4) and air cap adapter (6) will now slide forward from the gun body (8).
Gun head reassembly
1. Install a new o-ring (7) on the air cap adapter (6).
2. Install the thread locknut (25) onto the fluid inlet (24) as far as possible.
3. Install a new fluid inlet seal (26) into the recess area on the nozzle carrier (4) inlet port.
4. Slide the nozzle carrier (4) into air cap adapter (6) and insert into the gun body (8) as far as possible. Be sure the
nozzle carrier (4) extends into the hole at the back of the gun head. Install the needle seal (27) but do not tighten.
5. Rotate the nozzle carrier (4) until the fluid inlet port in the nozzle carrier (4) is aligned with the threaded hole in the
body. While in this position, insert the fluid inlet (24) and tighten firmly.
6. Tighten the needle seal (27) to approx. 12 ft.-lb. torque.
7. Tighten the fluid inlet (24) to approx. 25 ft.-lb. torque.
8. Tighten the locknut (25) to approx. 33 ft.-lb. torque.
