* Special note on lacquers and other oil based coating
When mixing or thinning:
Eliminate potential sources of fire.
• Turn off the HVLP sprayer, all other electrical appliances, spark or flame sources
• Follow lacquer and thinner manufacturer directions very carefully
Minimize vapors in the spray area. Eliminate all potential for spilling lacquer or
thinner in the spray area.
• Tightly recap all containers immediately after mixing or thinning and store
away from the spray ares
• Do not operate the HVLP turbine in the presence of open containers or spillage
• Make sure all vapors have dispersed prior to turning the HVLP sprayer on

ADJUSTING PACKING
Occasionally the packing nut, located in
front of the trigger as sem bly, will
require adjustment. The pack ing nut also
requires ad just ment 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 coating manufacturers do not
recommend thinning their materials. In
general, these in struc tions 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 pur chas ing spray
material.
Be sure to stir material thoroughly after
adding a thinning agent and before
checking the vis cos i ty. Fail ure 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 5). Refer to
Chart 1 for proper thinning
instructions.
Follow material
manufacturer's
recom men da tion for proper thinning
agent.
