CAUTION
Relevant standards apply to spraying and handling with the flammable liquids.
Regarding the flammability class of the coating materials the areas and rooms,
where the coating materials are used, must be marked and modified in compliance
with applicable standards and regulations. The gun earthing is implemented via
the high-pressure hose from the equipment, however with application materials
of the ignition point below 21°C (NITRO etc.) or with materials, which are heated
to values exceeding the ignition temperature due to operational reasons, an
additional earthing is recommended by the potential equalizing cable (use the
metal conductor, optimally the steel rope of ø 5 mm, resp. copper wire min.

crucial for dilution of the NH and cleaning of the gun.

indispensable pressure!
the contaminants causing the clogging by the air jet. Cleaning of
the rotating nozzles is much simpler: remove the contaminants
by rotation and flushing and put the nozzle back to operation by
turning back. During cleaning or any manipulation do not turn
the gun against yourself or any other person, lock the supply of
the NH and pressure control air.

solvent applicable to the sprayed NH into the high-pressure
section instead of the NH. After approx. 5 minutes, when the
solvent dissolves the residual NH, flush the gun by pulses and
observe the solvent colour. When the solvent without traces of

other use.
