3. Loosen the securing block (34), 

and remove the orifice plate (31). 
Unscrew the nozzle (18) currently 
fitted and screw the chosen nozzle 
onto the end of the inlet tube (30), 
taking care not to lose the white 
rubber seal ring (42) from inside the 
nozzle. Tighten the nozzle with the 
box spanner (28) stored inside the 
handle. Replace the orifice plate 
and securing block.

NOTE: 

The largest (3.6 mm) nozzle 

cannot be tightened with the 
box spanner. Instead, the 4mm Allen key must be used.

CONNECTING AND FILLING

1. Connect the air hose using an appropriate connector as necessary. An air 

regulator can be fitted to the gun first, which can be used to control the 
droplet size produced by the spray gun, turning clockwise to restrict the air 
flow. (The greater the flow, the smaller the droplet).

2. Turn the air supply on and check the functionality of the gun by squeezing 

the trigger before filling with paint etc.

3. Turn air off and fill hopper with material to be sprayed, (1.75 gallons max) 

Always mix the paint to the correct viscosity for spraying according to the 
manufacturer’s instructions. (DO NOT OVERFILL - the more paint the heavier 
the spray gun).

4. Hold the gun approximately 12” from wall to be covered, supporting the 

gun using the handle on the hopper.

5. Gently squeeze the trigger until resistance is felt whilst moving the gun from 

side to side. Check the coverage and change the orifice/nozzle size if 
necessary, or adjust the air flow regulator adjustment, if fitted.

6. Before using the gun, practice getting the feel of the trigger with the 

chosen settings.

7. The trigger stop can be used in order to select the same setting for repeat 

operations. Wait until the trigger is in the desired position before tightening 
the wingnut (8) to limit trigger movement.

SPRAYING DIFFERENT MATERIALS

The paint flow from the gun is adjustable. This is achieved by turning the orifice 
plate to a different setting and replacing the nozzle with one of a different size 
as above. If a pressure regulator is used this can also be adjusted to increase 
or reduce airflow, according to the material being sprayed.
