3.1 Set up gun as follows
•
Connect Duo-hose (twin hose for atomising air and fluid) to material pressure tank or other
means of feeding fluid and to compressor.
Translucent part of hose
: for fluid (gun connection “M”)
Blue part of hose
: for atomising air (gun connection “AIR”)
•
Set atomising air pressure to required spray droplet sizes by reducing valve (not part of the
spray gun).
•
Set material pressure to required material outlet and spray droplet sizes by a 2. reducing valve
(not part of the spray gun).
IMPORTANT!
Fluid output can be regulated individually, apply needle regulator (24.1) and counter nut
(23.1) for quantity of fluid flow.
Turning needle regulator right
: less fluid flow
Turning needle regulator left
: more fluid flow
When you are sure of fluid flow open trigger (19.1). Spray operation starts. You will notice that you
receive so called “pre-air” prior to opening fluid flow when pulling the trigger. When releasing trigger you
still have “purging-air” after needle has closed nozzle and fluid flow was stopped. This prevents that
fluid forms drop instead of the desired atomisation.
IMPORTANT!
After spray operation give a short period of time “pre-air” respectively “purging-air”. This
prevents that material blocked the nozzle.
3.2 Operating Information
•
Depending on viscosity of fluid nozzle bores are available in 0,2 ; 0,3 ; 0,5 ; 0,8 and 1,0mm
∅
(only one size of air cap is required).
•
Standard version of gun has flat spray pattern air cap with approx. 60° sprayangle (3.1.1). If
round spray is required, just replace air cap by a round spray air cap (3.1.2).
•
Flat spray air cap can be positioned for horizontal, vertical or any in between position of jet. For
special air caps with other sprayangels please contact the manufacturer.
CAUTION!
Never point the spray gun against persons. Wearing eye protecting is strongly
recommended. Spraying procedures cause noises depending on the used pressure. If
necessary, wearing of ear protection is recommended.
WARNING!
Danger caused by combustible and noxious spraying material. Safety instructions on fluid
can and material data of fluid manufacturer must definitely be observed.
Don´t smoke when spraying paints or solvents which have combustible properties. All electrical
installations within the spraying area must be explosion proof. Observe working safety regulations in
respect of protective clothing (masks, clothing, ear protection, etc.).
