6. Operation tips
•
Never use the spray gun without a reservoir [5] or when it’s empty to avoid damage to the pump.
•
Make sure the surface to be painted is clean and free of grease and dust. Mask any part that does not
need painting.
•
Do not use the spray gun in windy environments.
•
Hold the spray gun as level as possible when spraying. Do not sweep the gun like a pendulum (see the
illustration on page 2 of this manual). Try to move the spray gun with the whole arm in stead of with
the wrist.
•
Usually the distance between nozzle and surface should be 25~30cm. When applying a small quantity
of paint, decrease the distance, for larger quantities, hold the nozzle further away from the surface.
•
Do not tilt the spray gun more than 45° as paint might flow into the pump and air might be sucked up
in stead of paint. Always use the extension for overhead paint jobs (e.g. ceiling, car bottom…).
• Start spraying outside of the area to be painted, then move the spray gun across the surface with an
evenly and controlled movement speed. A fast speed will give a thin coat and a slow speed will give a
heavy coat.
•
The first coat should not be too thick, especially on vertical surfaces to obtain a homogeneous layer.
•
Only apply one coat at a time. If more layers are required follow the paint manufacturers’ instructions
on drying times.
•
When spraying larger areas or objects, it is best to use a crisscross pattern, either from left to right
then up to down or vice-versa. This will ensure maximum coverage.
•
Do not stop halfway a surface as this will lead to irregularities in the finishing. Also, do not stop
immediately when reaching the edge of the surface but continue until the whole spray beam has
moved passed the edge.
7. Cleaning and storage
• Cleaning is essential to keep ensure proper operation. Before cleaning always remove the power cord
from the mains.
•
Never submerge the spray gun in any liquid to clean it.
•
Disassemble the spray gun:
o remove the reservoir [5]
o remove the suction pipe and filter [7].
o remove the nozzle [6,A] and the valve [8,C]
o gently unscrew the spray basket [B] (anticlockwise).
o remove the cylinder [D] by pulling it out of the housing. Note: do not disassemble the spring [E]
and piston [F].
•
Thoroughly clean all parts and let them dry.
•
Lubricate all moving parts (piston, valve…).
•
Re-assemble the spray gun in the reverse order as it was disassembled.
