5. Preparation
Liquids
•
Before using the spray gun, determine the viscosity of the liquid.
•
Make sure the viscosity cup [10] is clean and fill it to the top with liquid.
•
Measure the depletion time of the cup. Refer to the table below for an overview of depletion times (in
seconds) for various types of paint.
plastic and latex paints 24~28 enamel 18~22
water-based paints 20~25 aluminium paints 22~25
primers 24~26 car bottom coating 25~35
varnishes 20~25 wood sealants 28~35
oil-based paints 18~22
•
If the measured depletion time is higher than indicated in the table, the paint must be diluted with a
suitable thinner. Mix well and measure the viscosity again. Repeat this step until the depletion time is
within the limits as shown in the table above.
•
Remove the reservoir [5] from the spraying gun by twisting it clockwise.
• Fill the reservoir [5] with the (diluted) paint. Do not fill above the 800 (ml) marker.
•
Make sure to clean the viscosity cup [10] thoroughly for future use.
Spray gun
•
Make sure the valve [8] is in place and tightly screw the appropriate nozzle [6] on the spray gun.
Note: operation without the valve [8] will result in poor painting results as the (rotating) valve ensures
an equal and steady paint flow.
•
For upwards painting (e.g. for ceilings or car bottoms), the nozzle extension [9] should be used. Make
sure the valve [8] is in place and tightly screw the nozzle extension [9] on the spray gun making sure
it is pointing upwards. Screw the nozzle [6] on the nozzle extension [9].
•
Look at the bottom of the spraying gun (without reservoir). Insert the suction pipe with filter [7] into
the hole closest to the spraying nozzle.
•
Place the spraying gun on top of the reservoir [5] making sure the filter [7] at the end of the suction
pipe is completely submerged. Hold the spraying gun by the grip [4] and turn the reservoir [5]
anticlockwise to secure it tightly.
•
Plug the power cord into a suitable mains outlet.
•
The spray gun should be tried out on a piece of test material e.g. a piece of cardboard.
•
Press and hold the spray button [3] to release liquid from the nozzle [6].
Note: it takes a short while before the paint comes out of the nozzle, the time which is needed for the
pump to suck up the paint and feed it to the nozzle.
•
Turn the flow regulator [2] to regulate the paint flow. Turn counter clockwise for maximum flow,
clockwise to decrease the flow.
