Operation and Maintenance Instructions for
CPR-FE
Spray Guns
Operation
1. Connect air supply hose at handle of gun.
2. Connect a pressurized fluid supply 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.
NOTE: Gun head disassembly is not recommended for normal cleaning and maintenance.
Not recommended to soak entire spray gun in solvent.
