If the paint takes longer than the recommended time to 
empty, then further thinning is required. Mix in a small 
quantity of the appropriate thinner and use the viscos-
ity test until the correct thickness is achieved. Some 
sprayable materials contain particles and lumps. These 
materials should be strained before 

fi

 lling the paint con-

tainer.

SPRAYING    

 C 

Fill the paint container with the correctly thinned and 
strained paint. Connect the spray gun to the mains 
supply. Aim the spray gun at a piece of scrap material 
and operate the trigger switch until paint is spraying. 
Adjust the output control 

 until the required 

volume of paint is spraying. Turn the output control 
in a clockwise direction (B) to reduce the 

fl

 ow and 

anti-clockwise (A) to increase the 

fl

 ow. Adjustment of 

the output control will affect the spray pattern. A poor 
spray pattern will concentrate the paint in the centre 
of the spray and give a blotchy 

fi

 nish. A good spray 

pattern will give even distribution of paint throughout 
the pattern.

SPRAYING TECHNIQUES    

 D 

To obtain the best results, keep your spray gun level 
and parallel to the surface at all times.
Keep the nozzle 25 - 30 cm from the surface and spray 
evenly from side to side or up and down. Do not spray 
at an angle as this will lead to paint runs on the surface. 
Use smooth and even strokes. When spraying large 
areas, use a criss-cross pattern as shown.

 E 

Never start or stop the spray gun while it is aimed at 
the surface to be sprayed. Evenly control the speed of 
movement of the spray gun. A fast speed of movement 
over the surface will give a thin coat and aslowspeed 
will givea heavy coat. Apply one coat at a time. If a fur-
ther coat is required, make sureyou observe the manu-
facturers drying time recommendations before apply-
ing a second coat. When spraying small areas, keep 
the output control on a low setting. This will avoid using 

too much paint and prevent overspray. Where possible, 
avoid stopping and starting when spraying an object. 
This can lead to too much, or not enough paint being 
applied. Do not tip the spray gun to more than 45°

CLEANING AND MAINTENANCE   

 F 

It is essential that the spray gun is cleaned thoroughly 
after every use. Failure to clean it will almost certainly 
result in blockages and it may not operate when you 
next come to use it! The guarantee does not cover 
cleaning a sprayer that has not been properly cleaned 
by the user.

The following action must be taken after every 
use.

1.  Empty any remaining material from the container.
2.  Clean the container thoroughly with the thinner 

thatwas used.

3.  Pour some thinner into the container and spray 

through the spray gun until only clean thinner is 
coming out of the nozzle.

4.Thoroughly clean the paint pick uppipeand 

fi

 lter  with 

thinner.

5.Clean the basket and nozzle and remove any other 

debris or paint that remains.

6.  Turn the spray gun upside down and apply a few 

drops of light oil to the two apertures (F). This will 
lubricate the piston and cylinder.

If your spray gun should require extra internal 
cleaning, it may be necessary to disassemble it. If 
so the following action should be taken.

1.  Remove paint container, pick up pipe and 

fi

 lter.

2.  Release the nozzle (H), valve (j), piston (K) and 

spring (L).

3.  Clean the cylinder (M) and all parts thoroughly with 

solvent.

4.  Apply a few drops of light lubricating oil to the pis-

ton, springand cylinder.

5. Reassemble the spray gun.

TROUBLE SHOOTING

Motor hums but does not spray or irregular spray-

ing.

1.  Worn swirl head
 

Replace swirl head.

2.  Pick up pipe not into the right position
 

Re-adjust pick up pipe.

3.  Blocked pick up pipe
 

Clean with thinner.

4. Blocked nozzle
 Clean 

nozzle.

5. Blocked

 lter

Clean with thinner.

6.  Control knob needs adjustment

Atomization is not good.

1.  Volume adjustment is not correct.
