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 29�
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,
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
