Operation
Intended Use
The compressed air gravity paint spray gun is suitable for application of
adhesive substrates and primers and top coats on metal and wood and for
general coating work. Note that abrasive, acid and fuel-containing materials
must not be processed.
The intended use also includes an operation following the operating instruc-
tions.
Any use beyond these parameters (different media, applying force) or any
changes (reconstruction, no original accessory) can lead to serious risks and
is regarded as use that is contrary to the intended purpose.
Before first Use
Unpack the air spray gun and the accessory and check all parts for any damage
in transit. Dispose of packaging materials or store it out of reach of children.
Plastic bags etc. may become a deadly toy for children.
Preparing the Surface to be painted
The object to be painted, or the surface, etc. has to be clean, dry and free of
grease and dust. Metal surfaces must be stainless. Since the fine sprayed paint is
dispersed in a very thin layer on the surface, roughness would have a negative
effect on the paint result.
Viscosity testing
Viscosity is the flow rate of a material. Measure the viscosity with a viscosity cup
(not included) as follows:
1. Thin the paint according to the manufacturer's recommendation. Start with less
thinner so you still can and add some thinner later.
2. Mix the paint thoroughly. Pour the paint into the viscosity cup or dip the cup to
the edge into the paint.
3. Measure the time in seconds until the liquid thread breaks off. This flow time is
called DIN-s. Thin the material as much as necessary until the liquid thread
already breaks off after approx. 20 seconds.
