Design features of the power tool
Sprayed material volume regulation (see fig. 8)
•
Using regulator
10
, you can adjust the volume of
the spayed material in order to get the desired work
result�
•
To decrease volume of the sprayed material, ro-
tate regulator
10 as shown in figure 8 (while spraying
material)� Note that the excessive decrease of the
sprayed material volume leads to poorer results of
treatment (insufficient impregnation, too thin a paint
layer, etc�)�
•
To increase volume of the sprayed material, rotate
regulator
10 as shown in figure 8 (while spraying mate
-
rial)� Note that an excessive increase of the sprayed
material volume results in drips on the treated surface
and overconsumption of the sprayed material�
Sprayed stream shape regulation (see fig. 9-10)
[CT31013, CT31014, CT31014M, CT31015]
You can adjust the shape of the sprayed stream (verti-
cal or horizontal) by rotating selector
3
together with
air cap
2
depending on the direction of the spray gun's
unit
8 movement (see fig. 9).
To select circular jet set spray width regulator
5
in posi-
tion shown onto fig. 10.
Power unit (see fig. 11)
[CT31014, CT31014M, CT31015]
The power unit
16
is designed to secure the spray gun
unit
8
during the movement of the power tool or during
the breaks in the work process� Also, the power unit
16
allows to compactly place the spray gun unit
8
and all
accessories during storage (see fig. 11).
Carrying belt
[CT31014, CT31014M]
To facilitate the transportation, as well as to provide
greater portability during the work, use the carrying
belt

Recommendations on the power tool
operation
Measurement of sprayed material viscosity (see
fig. 12)
The viscosity of the sprayed material should not ex-
ceed the maximum allowable value (see technical data
table)� Thicker materials should be diluted�
Please
note! Always use an appropriate solvent, other-
wise the lumps will form that will result in clogging
the power tool.
Measure the viscosity using measuring funnel
20
� The
temperature of the compound should be 20-22°С.
•
Stir the compound thoroughly, immerse measuring
funnel
20 into it, and wait until it fills (see fig. 12).
•
Lift measuring funnel
20 up and let the liquid flow
out. Measure the time of liquid flow out (DIN-s) of
measuring funnel
20
using a stop-watch (from the start
of the flowing-out to jet separation). Approximate rec
-
ommended viscosity values for different materials are
given below:
•
impregnating agents, varnishes, synthetic resins -
undiluted, 30 DIN-s max�;
•
synthetic paints, transparent varnishes - 15-35
DIN-s;
•
acrylic paint - 20-35 DIN-s;
•
preservatives, pesticides, oils for wood - undilut-
ed, 35 DIN-s max�;
•
disinfectant and cleaning agents, polishes - 35
DIN-s;
•
car paint - 18-22 DIN-s�
•
After you are done with the measurements, thor-
oughly clean measuring funnel
20
(using an appropri-
ate solvent)�
Surface preparation
•
The treated surface must be cleaned, dried, and de-
greased�
•
Glossy surfaces should be roughed (with sandpa-
per), dust removed, and the surface should be de-
greased�
•
The surrounding surfaces that need protection
from precipitation of the "mist" of the sprayed mate-
rial should be covered with thick materials (paper, film,
etc�) and lined with adhesive tape, when necessary�
Work sequence (see fig. 2-3, 13)
•
Prepare the sprayed material and surface as de-
scribed above�
• CT31012 -
detach reservoir
6 , fill it with the sprayed
material, and connect it to the spray gun (see fig. 2).
• CT31013, CT31014, CT31014M, CT31015
-
unscrew cap 7
, fill the reservoir
6
with sprayed material
and screw cap 7
(see fig. 3.2).
•
CT31013, CT31014, CT31014M, CT31015
- adjust
the stream shape�
•
Switch on the power tool, adjust the volume of the
sprayed material as described above� The "mist" of
spray deflection should be homogeneous and fine.
•
Do a trial treatment on an unnecessary piece of the
same material in order to make sure that the adjust-
ments are correct�
•
Spray material from a distance of 5-30 cm from the
surface (see fig. 13.1).
• CT31012 - use flexible extension hose 17
when
painting horizontal or sloping surfaces�
•
CT31013, CT31014, CT31014M, CT31015
-
slightly tilt the spray gun when painting horizontal or
sloping surfaces�
•
Start spraying beyond the bounds of the treated sur-
face�
•
Move the spray gun moving your arm as shown in
figure 13.1, and not only the wrist (see fig. 13.2). The
distance between the spray gun and the treated sur-
face should be constant - this will ensure that the mate-
rial is sprayed evenly�
•
Smoothly move the spray gun as shown in
figure 13.3. Each successive strip should partially
