CORROSIVE PRODUCT
WARNINGS
CLEANING
HEALTH HAZARD
Before any maintenance work, empty the
gun and disconnect it from both, the
compressed air supply, and the liquid
supply. Use only original AIRCOM®
accessories, spare parts, and related
components: any other product not
supplied by AIRCOM® is not approved or
authorized. AIRCOM® is not liable for any
damage caused by using non-original
spare parts and accessories.
Our guns can be used with the majority
of water, or solvent-based pigments for
coating and finishing all types of
surfaces. However, they are not
designed to spray abrasive and/or
corrosive products. If abrasive and/or
corrosive products are used, guns with
components made of the appropriate
material can be ordered.
Use exclusively appropriate liquid
cleaners with neutral pH 6-8. Do not use
acids, alkaline solutions or other cleaning
agents containing sodium hydroxide,
which are aggressive for cleaning the
exterior of the gun. Do not immerse the
gun in liquid cleaners that may cause
corrosion of the product. Clean all
material passages by propagating water
within the paint circuit: inadequate
cleaning can cause damages to the fan
shape. While cleaning, avoid scratching
the surfaces of the air nozzle holes and
the dipstick.
Some chemicals, once sprayed, may be
harmful and cause irritation or health
disorders. Careful reading of all labels
and instructions on how to use the
product are necessary. Use of the
product is restricted to trained technical
personnel, with the use of special safety
glasses when adjusting the gun and,
while the system is operating.
