The surface to be sprayed should be free of dust, dirt, and grease. In some instances, a
primer coat should be applied before spraying the final coat.
PREPARATION OF PAINT TO BE SPRAYED
Most paints and stains are supplied ready for brush applications. They may need to be
thinned before using in the Spray Gun. Refer to the paint manufacturer’s recommendations
for thinning their product. Test the viscosity of the product before thinning.
1. Purchase fresh paint and have it mixed thoroughly by machine.
When using lacquer, stir to mix the liquid. When shaken, air bubbles are produced
which may give an uneven spray. If the paint or other fluid is old, it may be necessary
to strain the fluid of all debris and lumps before spraying.
2. Check the viscosity of the paint using the Viscosity Cup (30).
After mixing the paint, fill the Viscosity Cup (30) up to the brim with paint. Do this over
the paint container. Measure the time it takes for the cup to empty. The time should be
between 15 and 30 seconds for proper operation in the Spray Gun. The table below
gives the recommended (viscosity) times for various types of paints and stains.
Spraying Materials Recommend Viscosity Time
(in Seconds)
Plastic and latex paint 24 ~ 28
Water based paints 20 ~ 25
Primers 24 ~ 28
Varnishes 20 ~ 25
Oil based paints 18 ~ 22
Enamel paints 18 ~ 22
Aluminum paints 22 ~ 25
Car under-seal 25 ~ 35
Wood sealers 28 ~ 35
Wood preservatives No thinning required
Wood stains No thinning required
If the paint takes longer than the recommended time to empty from the Viscosity Cup,
then further thinning is necessary. Mix in a small quantity of the appropriate thinner
and test the viscosity again until the correct viscosity is achieved. If particles or lumps
are present, strain the paint using a disposable strainer (not supplied) until clean.
FILLING THE CANISTER
1. Push the Switch Lock (21) to the Off position.
2. Unscrew the Canister (25) from the Canister Lid (11).
3. Carefully pull off the Suction Tube (23).
4. Turn the Spray Gun upside down and apply a few drops of light oil into the two holes
(X and Y) under the Lid (11). This helps keep the Spray Gun parts lubricated and
minimizes clogging. Refer to the photo at the top of page 8.
