(See Figure 6)
1. Remove spray gun from air supply.
2. Remove fluid control knob and the
fluid needle spring.
3. Remove air valve spring and store
the spring in a safe place so it can be
replaced if necessary to convert back
to a non-bleeder type arrangement.
4. Insert fluid needle spring and replace
fluid control knob.

Preparation
MATERIAL PREPARATION
1. Before using desired material in
the spray gun, spray a compatible
thinner or solvent through the gun
to remove any contaminants and
residue.
2. Thoroughly mix the material in
accordance with the manufacturer's
instructions. If necessary, thin per
paint manufacturer's instructions.
Strain material through a paint
strainer. Test the consistency of the
material by making a few strokes
on a cardboard target. Be sure the
spray material is clean and free from
lumps.
3. Fill the canister about 3/4 full
with material and start the air
compressor. Be sure the hose(s)
is long enough to allow a full
movement of the gun across the
surface to be painted.
4. Be sure that the air pressure
regulator is set for the proper
operation of the gun. Refer to the
specifications section. Air pressure
should be checked at the spray gun
inlet with the trigger pulled.
5. Set up a piece of cardboard or other
scrap material to use as a target and
adjust for best spray pattern.

Fluid Control
The fluid control knob will control
Knob
trigger travel and the amount of
material flowing through the gun.
(Turn the knob clockwise to reduce
flow, counterclockwise to increase the
flow.) This adjustment depends, in part,
on the amount of air flowing through
the gun. Air flow can be adjusted only
at the compressor's pressure regulator.
Spray test patterns on scrap cardboard
with gun 8 inches away from surface.
Trigger short, one second bursts and
make adjustments with this knob until
the pattern is the desired oval shape and
the material is evenly distributed on the
surface with no heavy or thin spots. The
pattern should feather out at the edges
(See Figure 8).
NOTE: If there is sagging, too much
material is being applied. If there is an
"orange peel" effect, the material is too
thick.
Model 2Z364G
1. Adjust air pressure to the spray gun
according to the recommendations
supplied with the spray material. This
air pressure usually falls between 30
psi - 50 psi.
2. Set pattern size to desired shape. For
full pattern, open pattern control
knob by turning counterclockwise.
For a round pattern, turn pattern
control knob clockwise (See
Figure 7).

3. Turn fluid control knob fully
clockwise until closed.
4. With gun 8 inches away from
surface, trigger a short, one second
burst while turning fluid control
knob counterclockwise. Observe
the spray pattern on the target and
adjust the fluid control knob until
the desired pattern (atomization) is
obtained (See Figure 8).
