Installation
1. Mount gun on a support. Use 12 mm (15/32“) Ø hole in gun body.
2. Connect compressed air to quick connection no. 71.
Please use clean lubricated air.
3. Install 3-way control valve (minimum flow Ø, ¼”) as close as possible to the gun.
When using a 3–way solenoid valve, valve is “normally closed” when de-energized. Actuation of valve can
be made through an automatic timer or manually.
4. Connect material feed (compound hose) to connection no. 56. A dirt trap (strainer) in feed line is
recommended. Strainer mesh size: 30.

1. Open material shut- off valve no. 55.
2. Open bleed valve nut no. 93 slightly until material emerges.
Or put the blade of a screwdriver to the groove of the nozzle nut no. 1 and press down the nozzle until
no air will come out. After the screwdriver has been removed, the system is closed automatically.
Please check that the position of the nozzle has not changed.
3. Actuate control valve to vent gun and then close bleed valve nut no. 93.
4. Adjust quantity of spray by means of knurled knob no. 69.
