controller to put it to sleep.
2. See Figures 2-7 and 2-6. Remove the nozzle from the spray gun:
Flat or Corner Spray Nozzle: Unscrew the nozzle nut (1) and remove
it along with the nozzle (2) from the spray gun.
Conical Nozzle: Unscrew the deflector cap (1), then remove the
deflector (2). Unscrew the nozzle nut (5) and remove it along with the

3. Pull the electrode support out of the spray gun.
4. Pull the powder hose adapter out of the spray gun. Place the end of the
powder hose in the booth. Disconnect the hose from the pump. Blow
out the hose from the pump end. Check the hose adapter and powder
hose for wear and replace if worn or damaged.

holder for wear. Replace worn or damaged parts.
Make sure the system is securely connected to a true earth ground before
spraying powder.

do not fall within the specified ranges.
