WARNINGS
MAINTENANCE AND
CLEANING
CORROSIVE PRODUCT
WARNINGS
Our guns can be used with the majority
of water, or solvent-based pigments for
coating and nishing 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.
MAINTENANCE
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.
HEALTH HAZARD
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.
CLEANING
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.
