Intended Use; Before First Use; Operation - Westfalia 98 31 88 Mode D'emploi Originale

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 petrol-
containing materials must not be processed.
▪ The intended use also includes an operation following the operating
instructions.
▪ 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. The operator is liable for any damage caused by improper
use.

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. There is risk of
suffocation!
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.
Paint Jet Adjustment
▪
For a high jet (vertically), align the nozzle (1g) horizontally. Use
this setting for spraying larger areas.
▪
For a wide jet (horizontally), align the nozzle (1g) vertically.

Operation

1. Before starting work, check the trigger (1e) to make sure it
moves freely.
2. The paint flow regulator (1c) is completely shut by factory default. Turn the paint flow
regulator counter clockwise to open it. Turn the fan regulator (6) counter clockwise until the
first thread pitch is visible. Open the air flow regulator (1f) by turning counter clockwise.
3. Connect the spray gun to the compressed air supply. The air should be regulated and
filtered.
4. Setup the air pressure according to the parameters supplied with the paint to be processed.
