INSTALLATION
1 Make sure the power supply voltage is the same as the
value indicated on the machine technical dataplate.
2 Make sure the switch is in position "0" (A).
3 Connect the machine plug to an extension.
(minimum 1200W)
4 Connect the hose to the multistage centrifugal blower (B).
5 Fitting the support belt.
PAINT AND MATERIALS USED
Paint manufacturers often specify the % for thinning the
products: in general this refers to brush or roller applications.
In fact with the gun the % must be higher.
Tell you paint supplier that the product will be applied
using an HVLP (low presssure anf high volume) spray gun.
Generally, in such case, the product must be thinned (try
thinning a small amount of paint before thinning all of it).
VISCOSITY
"Viscosity" is the technical termused to indicate if a product
is very liquid or very thick: in the first case the viscosity is
said to be low, while in the second case ir is considered to
be high. The viscosity measurement is expressed in second.
To measure viscosity, fill the viscosity meter supplier with
the machine with paint, and note how long it takes for the
paint to pass through the hole at the bottonm of the viscosity
meter (C). The time measured is the viscosity value and is
expressed in DIN-s.
GENERALITY
This machine can use products with a viscosity ranging
from 10 to maximum of 35 (35 DIN-s).
A paint with a much higher viscosity can be used only for
water-soluble products for autdoor and indoor
wall applications. The quantity and type of paint are very
important.
The main viscosity values for the most commonly used
products are:
Filler 10 to 20
Wood dye 15 to 25
2-pack paint
20 to 35
Oil paint
The product manufacturer's instructions for the type of
thinner and the quantity, in % to be added (this may vary
from 5 to 50 %).

PREPARING THE OBJECT OR SURFACE TO BE TREATED
To obtain good results, the objects or surface to be treated
must be cleaned.
- Remove any traces or rust or scaling from the old paint
and, if necessary, rub it using sandpaper
- Stucco or rub with sandpaper, where necessary to make
the surfaces smooth
- Carefully read the instructions indicated on the paint can.
Manufacturers usually suggest to apply a fixative
before painting to obtain the best results and, above all,
to save paint.
PREPARING THE PRODUCT FOR PAINTING
Shake weel. Pour paint inside the spray gun reservoir,
without filling it to the top (maximum 3/4).
Use a stick to mix and stir the product (D).
Thin the product following the manufacturer's instructions.
If necessary GRADUALLY ADD THINNER AFTER MAKING
TESTS ON A PIECE OF CARDBOARD OR WOOD.
After checking that the product has been correctly thinned,
the entire can be thinned. For more specific information
about viscosity see relative section.
HVPL SPRAY GUN
Mount the gun container and fully tighten.
To connect the hose to the gun grip (E).
To select the type of spray required , loosen the adjustment
ring (F - 1), adjust the position, orienting the nozzle (F - 2)
to obtain (G):
HH Horizontal spray
VV Vertical spray
CC Round spray
The gasket (G - 1) includes 4 orientation notches that help
position the butterfly nozzle (G - 2). The position is fixed by
a tab that protrudes from the bottom.
After selecting the type of spray, tighten the adjustment
ring (G - 3). The horizontal or vertical sprays (HH -VV) are
recommended for large surfaces. The round spray (CC) is
used instead for small objects or for areas that are difficult
to reach (corners, angles, etc.).
OPERATION AND USE
The atomiser supplies the compressed air needed to
operate the machine.
Air flows from the butterfly nozzle and paint is sprayed only
when the trigger is pulled.
Start-up
Turn the switch ON/OFF to start the machine.
