Operating Instructions and Parts Manual
3. Using the following procedure,
check viscosity of spray material
before locking gun onto the paint
cup (Figure 4).
The viscosity stick
is located in storage
compartment.
a. Dip viscosity stick into material.
Remove stick from cup. Wait until
the material stream becomes drips.
b. Estimate the time interval between
the first three drips. The time will
vary depending on the thickness
(viscosity) of the material.
c. The material is adequately thinned
if time interval is about one second.
d. As a general rule, if the time
between drips is more than one
second, the material is too thick.
!
NOTICE
Add thinning agent, stir thoroughly
and check again for proper viscosity.
4. To tighten and lock the cup, place
retainer arms securely around
retaining pins on the paint cup.
5. Move locking lever clockwise to
locked position. (See Figure 5).
6. Attach air hose quick-connect fitting
to gun.
The quick-connect
fitting outer sleeve
is spring loaded and must be pulled back
to be attached or removed from the gun
(Fig. 6).
Always practice before spraying in work
area. Use cardboard to make gun
adjustments if necessary.
!
NOTICE
1. Keep gun parallel and 4" - 9" from
surface of object being sprayed. (See
Figure 7). If the material delivery is
adjusted for a small narrow pattern, it
may be necessary to move closer to
the work surface.
2. Move gun in a smooth even stroke.
Begin stroke before pulling trigger
and continue the stroke after
releasing trigger.
3. For best results overlap each stroke by
25 to 50%.
4. To adjust spray pattern, loosen retain-
ing ring and turn air cap to desired
pattern position (See Figure 8).
5. To adjust material flow, turn material
control knob clockwise to decrease
and counterclockwise to increase (See
Figure 9).
