This spray applicator can be used with products having a viscosity ranging from 25 to in ex-
cess of 75 seconds. Dip the viscosity cup into the material and fill up. Time how long it takes
for the viscosity cup to empty (Fig.3).
Using the above chart (or manufacturer’s instructions) as a guide determine if the material
requires further thinning, if so then thin accordingly.
Some paints are outside the ranges above. Please contact our helpline for further informa-
tion.	Fig.3

OPERATION

●Fill the paint container with the material to be sprayed. DO NOT OVERFILL above MAX level indicator. Push the Feed Tube firmly into the base of the spray applicator body (gun ’P’ only) and re-fit the paint container into the spray applicator body. (See exploded view on page 3 to show the fitting detail for the different spray applicator types.)

●Unwind the hose from the Carrier Stand & screw the motor end of the hose to the outlet port at the front of the turbine unit. Connect the spray applicator end of the hose to the spray applicator using the quick release connector. Uncoil the power cord and plug it in to a suitable power outlet.

ALWAYS KEEP THE MOTOR UNIT AS FAR AWAY FROM THE SPRAYING AREA AS POSSIBLE TO PRE- VENT PAINT CONTAMINATING THE MOTOR.

MASK OFF ANY AREA YOU DO NOT WISH TO SPRAY.

Once you have set up ready to spray, switch on the unit. No paint will be sprayed until the trigger on the spray applicator is gently pulled. Before starting any work on spraying actual objects we suggest you spend some time practising on cardboard or newspaper until you have got used to how the spray applicator works.

SETTING UP YOUR SPRAY APPLICATOR

●Choose the best Needle & Fluid Tip for your application.

Your SprayPort is supplied to you with a 2.0mm diameter Needle & Fluid Tip. This is a good size for most ap- plications. However, there are other sets available to cater for a wider range of materials that you may want to spray. In general, the larger the diameter of the Needle & Fluid Tip, the more suitable it is for higher viscosity ma- terials. The larger diameters also allow a greater volume of material to be applied. The smaller diameters are more suitable for low viscosity materials & lighter application. For the SprayPort type “P”, Needle & Fluid Tip sets are available at 1.0mm and 1.5mm diameter. For the Spray Port type “A”, Needle & Fluid Tip sets are available at 1.0mm, 1.5mm and 2.5mm diameter. See page 8 for details.
