ORIGINAL INSTRUCTIONS

ce and spray evenly from left to right and up and down 

with slow movements.

Do not spray at an angle, as 

this will cause the paint to form droplets on the surfa-

ce.

When spraying large areas, use a correct working 

plan (11).

Spray moving the arms and not the wrist.

Control the speed of the paint spray gun to achieve 

a smooth, regular movement.

Moving too quickly will 

cause the paint layer to be too thin.

Similarly, moving 

too slowly will cause the paint layer to be too thick.

Apply the coats of paint one by one, leaving them to 

dry for the times indicated by the manufacturer.

NEEDLE, NOZZLE AND REGULATOR CHANGE.

Unscrew and remove the spray direction control (A). 

Unscrew and remove the nozzle regulator (E). Subse-

quently, pull back the fluid-flow needle until it is comple

-

tely removed. Using the wrench provided, unscrew and 

remove the fluid-flow nozzle from the head, then screw 

in the new fluid-flow nozzle. Insert the new fluid-flow 

needle. Then screw in the nozzle regulator (E). Screw 

in the new spray direction control (A).

IMPORTANT.

Using products containing halogenated hydrocar-

bons may cause chemical reactions that lead to 

explosions.

When using solvents and detergents 

containing halogenated hydrocarbons, such as 

1,1,1-trichloroethane and methylene chlorate, 

chemical reactions may occur in the tank, gun and 

galvanised parts (when 1, 1, 1-trichloroethane co-

mes into contact with water droplets it produces 

chlorohydric acid).

We recommend using products 

that do not contain these elements.

Before using 

the paint spray gun and its accessories, these 

must be cleaned with cleaning solvent, to remove 

the protective film applied before packing.

Acid or 

alkaline products must not be used to clean the 

paint spray gun.

MAINTENANCE.

Drain all condensation from the air compressed 

tanks and hoses (12). To do so, open the decom-

pression taps and other drainage valves in the 

tanks.

IMPORTANT.

The paint spray gun has been designed for a long 

working life with minimum maintenance.

Optimum 

use depends on correct care of the paint spray gun 

and regular cleaning.

The paint spray gun may be 

cleaned effectively using compressed air.

If com-

pressed air is not available, use a brush to remo-

ve dust from the paint spray gun.

Cetain cleaning 

agents and solvents damage plastic parts, among 

them are gasoline, carbon tetrachloride, chlorina-

ted cleaning solvents, ammonia and household 

cleaners containing ammonia.

Do not use any of 

these to clean the paint spray gun.
