Operation and Maintenance Instructions for FE-LCFM Spray Guns
Operation
1. Connect air supply hose at handle of gun.
2. Connect a pressurized fluid supply to the gun fluid inlet.
3.Fluidflowcan be controlledusingthe fluidcontrolknob, thisrestrictsflowbylimitingneedletravel.It isbestto control
fluid flow byproper 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 maintenanceis essential toinsure proper gun operation.
Severalstates prohibitsprayingsolvent into theatmosphere andrequirethe use ofcoveredgun 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:
Removeair capand cleanseparatelyusing 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 disassemblyis not recommended for normal cleaning and maintenance.
Not recommended to soak entire spray gun in solvent.
