• Strive to have the object to be coated
hanging. The distance between the gun
and the object should be about 20 cm.
Activate the high voltage by pressing the foot
controller (11), and the green indicator (16)
lights up. Now you can cover the object with
powder from different directions and with
varying angles. Adjust the air pressure with
the adjusting screw (18) if necessary.
• The gun loses efciency if toner accumulates
on the emitter (13). Solve this by rst
switching off the switch (17), discharging
the emitter by touching the earth terminal,
aspark discharges the high voltage. Then
wipe the emitter clean with a clean cloth.
• When you have applied the desired amount of
powder, switch off the switch (17), discharge
the emitter (9) by touching the earth terminal,
a spark will discharge the high voltage.
Bake the object
Make sure that the oven is prepared and that it
has reached the correct temperature. Wear suit-
able gloves when placing the item in the oven,
avoid bumping into or scratching the surface of
the item. Bake the item according to the pow-
der manufacturer’s recommendations (usually
15minutes). Larger objects may need longer, the
powder gradually melts, from a dull at surface,
to a soft glossy nish. When baking manifolds or
rims, check every 5 minutes until you see that the
powder begins to take on a glossy surface over
the entire object, add another 10 minutes. If the
object has not been nished after 30 minutes,
you should look for a cause of error. Be careful
when baking, if the item is in the oven for too
long, the surface will be rough and may need to
be removed or redone.
Be sure to bake the items in a well-ventilated area
and use activated carbon respirators. Allow the
item to cool gradually when done by turning off
the oven and opening the door ajar. Note Too fast
cooling can cause the gloss to fade.
Clean the gun
When you are done with one colour, the gun must
be cleaned before using another colour. Start by
turning off the power switch (17). Touch the emit-
ter (9), the ground terminal (10) to discharge the
high voltage. You can now safely remove the paint
container (4). Unplug the power cord from the wall
outlet. Wipe the diffuser (12), the inlet pipe (6), the
outlet pipe (5) and the container (4), blow clean
with 3 kg of compressed air. Never use organic
solvents when cleaning the container.
The toner
Keep toner stored in a tight container to prevent
itfrom absorbing moisture. Mixtures between dif-
ferent powders, dusts and dusts can cause pits
in the surface. Never use solvents when cleaning,
only compressed air. You can reuse powders that
have been collected from a clean surface in a
spray can and that have not been contaminated
by anything. In certain concentrations, the toner
can be ammable and explosive, never use a
vacuum cleaner to suck up discarded powder.
Troubleshooting
Grooved surface:
Make sure the gun is properly cleaned of previous
toner. Some colours are made of polyurethane
other polyester, if you mix these the result can be
bumpy. Make sure the item is properly cleaned.
Porous surface:
If this occurs, remove the powder coating with
paint removal (may take a long time, cover with
plastic to reduce evaporation). Rinse with water
and prepare with a primer. Parts in cast iron, die-
cast, cast aluminum and magnesium can give off
precipitates that give a porous surface. This can
be remedied by preheating the object.
Preheating:
The time the object needs to be preheated varies
with the size. Preheat in temperatures between
95 - 200 ° C. Wipe with a white cloth until no pre-
cipitates appear. Allow the item to cool to room
temperature before powder coating.
Orange peel:
The fact that the surface has a light appearance
of orange peel is almost inevitable when it comes
to polyester-based powders. You can usually x
the surface by wet sanding it with a 400 paper
and nishing with chrome polish. Another cause
can be supercharged powder, which stands
on edge, like hair. Stop applying powder if this
occurs and try to blow away the cumbersome
grains with a light jet of air. If the powder settles
unevenly, it may be due to moisture, then replace
the water separator and rell the powder. Baked
powder can be post-treated in the same way as
liquid surface treatments.
Bad spray image:
If the gun does not spray properly, it may be due to
too low air pressure, water in the water separator
both cause malfunctions. Adjust the air pressure
or replace the water separator. Also check the
paint container so that there is enough space for
the powder to ow properly. There should be at
least 25 mm free space from the bottom.
