Characteristic curves
The characteristic curves show the air flow
rate for various nozzle sets and air caps for
different air pressures.

Safety recommendations
WARNING!
Danger of explosion due to chemical
reactions
Material, halogenated hydrocarbon-based
rinsing agent or cleaning agent can
chemically react with aluminum compo-
nents of the product. Chemical reactions
can cause explosions. Serious injuries
and death can be the consequence.
– Only use rinsing agents and
cleaning agents that do not contain
any halogenated hydrocarbons.
NOTICE!
Material damage due to dried material
residues
If material residues dry in the product,
that can harm components.
– Rinse product immediately after
each use.
6.2
Checks
1. Perform the following checks during oper-
ation:
Check air connection for correct seat
and leaks.
Check air car for cleanliness.
Check nozzle for cleanliness.
6.3
Selecting air cap
You can convert the spray gun for various
uses by swapping the air cap.
Air cap LP
The air cap LP is used for low viscosity (up
to 30 s/DIN cups, 4 mm) solvent-based
coating materials (single 1-component paints
and 2-component paints) and water-based
ones. It is used primarily for the final
painting.
Air cap LC
The air cap LC is used for solvent-based
coating materials (1-component paints and
2-component paints) and water-based ones.
It is used for application of fillers, basecoats
and topcoats. If usied with a hardened
nozzle, coating materials with abrasive addi-
tives (coating materials containing zinc and
aluminum) can be applied.
Air cap LE
The air cap LE is used for solvent-based
coating materials (1-component paints and
2-component paints) and water-based ones,
if higher outflow rates are required. Coating
materials with abrasive additives (coating
materials containing zinc and aluminum,
enamel, glaze) can also be applied.
