IMPORTANT: Before using the gun for the first time, tighten the needle
packing until the needle starts to bind. Then loosen the packing nut just
enough so that the needle moves freely.
The following hazards may occur during the normal use of this equipment. Please read the
following chart before using the equipment.
Area Hazard Safeguard
Tells where hazards may occur. Tells where hazard is. Tells how to avoid the hazard
Spray Area-
Fire Hazard
Solvent and coatings can be highly
flammable or combustible especially
when sprayed.
Adequate exhaust must be provided to
keep air free of accumulations of flammable
vapours.
Smoking must never be allowed in the
spray area.
Fire extinguishing equipment must be
present in the spray area.
Solvent Spray During cleaning and flushing, solvents
can be forcefully expelled from fluid and
air passageways. Some solvents can
cause eye injury.
Wear eye protection
Toxic Substances Certain materials may be harmful if
inhaled, or if there is contact with the
skin.
Follow the requirements of the Material
Safety Data Sheet supplied by your coating
material manufacturer.
Adequate exhaust must be provided to
keep the air free of accumulations of toxic
materials.
Use a mask or respirator whenever there is
a chance of inhaling sprayed materials.
This mask must be compatible with the
material being sprayed and its
concentration.
Explosion Hazard-
Incompatible Materials
Halogenated Hydrocarbon solvents - for
example: Methylene Chloride and 1,1,1 -
Trichloroethane are not chemically
compatible with the aluminium which may
be used in many system components.
The chemical reaction caused by these
solvents reacting with aluminium can
become violent and lead to an equipment
explosion.
Guns with stainless steel fluid passages
may be used with these solvents. However,
Aluminium is widely used in other spray
application equipment - such as material
pumps, cups and regulators, valves, etc.
Check all other equipment items before use
and make sure they can also be used
safely with these solvents. Read the label
or data sheet for the material you intend to
spray. If in doubt as to whether or not a
coating or cleaning or cleaning material is
compatible, contact your material supplier.
