Operating Instructions and Parts Manual
General Safety
(Continued)
Do not carry TURBINE while spraying.
Keep the turbine at maximum distance
from spraying area.
Static electricity can be produced by HVLP
spraying. Make sure any electrically
conductive object being sprayed is
grounded to prevent static sparking. The
sprayer is grounded through the electric
cord. If an extension cord is necessary,
the cord must be a grounded, 115 volt,
three wire type cord.
Hazardous vapors: Paints,
solvents, insecticides, and other
materials may be harmful if
inhaled causing severe nausea,
fainting or poisoning.
Always use a respirator or mask. Read all
instructions with the mask to ensure the
mask will provide necessary protection
against inhalation of harmful vapors.
NEVER point spray gun at any part of the
body or at anyone else.
Tipping gun causes clogs. Dried spray
material also clogs pressure delivery tube
and fittings. The spray gun will not
function when clogged.
When not in use, be sure to disconnect
hose and place gun on a solid, level
surface to avoid tipping.

Components

(1) Gun - fully assembled, with 1.00 mm
"all purpose" needle/nozzle installed
(1) .75 mm "fine" needle/nozzle - located
in storage compartment

Setup

NEEDLE AND NOZZLE ASSEMBLY

IMPORTANT: The needle and nozzle are
a matched assembly. It is very important
that both the needle and nozzle are cor-
rectly selected and installed. The
needle/nozzle kits are identified by a
number inscribed on each component.
Make sure the numbers on the nozzle
and the needle match. Failure to match
these two components will result in poor
finish quality.
1. Remove retaining ring, air cap, air
flow ring, nozzle, material control
knob, spring, and needle assembly
(Fig. 2).
2. Install appropriate needle/nozzle
assembly selected for material to be
sprayed.
3. Reassemble needle assembly, spring,
material control knob, nozzle, air
flow ring, air cap, and retainer ring.
The four raised

knobs on the air
flow ring must be facing forward when
assembled.
4. Attach quick connect fitting to hose.
ADJUSTING PACKING
Occasionally the packing nut, located in
front of the trigger assembly, will require
adjustment. The packing nut also requires
adjustment when needle/nozzle assembly
is changed.
1. Turn material control knob clockwise
at least 3/4 of the way in.
2. Use wrench to tighten packing nut.
Turn clockwise until the needle will
not return to the closed position
when trigger is released. Do not
overtighten packing nut.
3. Loosen packing nut (approx. 1/4 turn)
until needle returns freely to the
closed position.

Preparation

PREPARING TO SPRAY
Some manufacturers do not recommend
thinning their materials. In general, these
instructions apply only when a brush or
roller is used. Thinning may be necessary
if materials are to be sprayed. Check with
paint supplier for specific details when
purchasing spray material.
Be sure to stir material thoroughly after
adding a thinning agent and before
checking the viscosity. Failure to properly
mix material results in a poor finish.
NOTICE: Some latex finishes are very
thick and require a great amount of
thinning and mixing. Add a latex paint
conditioner (available at most home
centers) to the paint to improve spray
performance.
1. Strain paint before spraying.
Unstrained paint may affect material
flow and spray pattern. When spray-
ing thin materials such as lacquer or
stains, consult with material supplier
for proper strainer mesh number.
2. Pour material into paint cup. Fill cup
only 1/2 to 3/4 full if thinning is
required. (See Figure 3). Refer to
Chart 1 for proper thinning
instructions.
