Selecting the Proper Needle/Nozzle/Air
Cap Set
The
High V
nozzle sets range in size to provide dif
rates. Chart 1 shows the recommended combinations
based on fluid viscosities and flow rates.
As a general guideline, use the fluid nozzle that will
give the required flow with the needle fully triggered at
the lowest fluid pressure.
For low flow rates or light viscosity fluid, select the
smaller nozzle sizes.
For high flow rates or high viscosity fluid, select the
larger nozzle sizes.
Using an air cap size that is smaller than the nozzle/
needle size is not recommended.
NOTE: T
fluid pressure gauge may be connected temporarily to
the gun fluid inlet to determine the fluid pressure. See
Accessories.

The M-1265 HVLP Spray Gun
The
Model M-1265 HVLP Spray Gun was designed to
produce the highest quality finish with today’
well as the the Low V
fluids of tomorrow
.O.C. (volatile organic compound)
.
This spray gun can spray most coatings or finishes
currently being used for automotive refinish, industrial,
aerospace, marine, wood, plastic and architectural
applications, while easily operating from any paint
delivery system, including cups, pressure pots, or
remote pumps for production line operation.
The Model M-1265 HVLP Spray Gun typically utilizes
65 psi (444 kPa, 4.4 bar) inbound air pressure to
produce high quality paint finishes at 10 psi (0.07 bar)
atomizing air pressure.
The air regulator must have a minimum air flow
capacity of 30 scfm at 100 psi (0.7 MPa, 7 bar) air
pressure.
NOTE:
If the gun’
s hanging hook is needed, remove
the gun trigger and replace the gun plate with the
hook, then reinstall the trigger
. See the parts drawing,
page 24.

Ventilate the Spray Booth
WARNING
To
prevent hazardous concentrations of
toxic and/or flammable vapors, spray
only in a properly ventilated spray booth.
Do not operate the spray gun unless
ventilation fans are operating.
Check and follow all of the National,
State and Local codes regarding air ex
haust velocity requirements.
Check and follow all local safety and fire codes.

Setup
1. Connect the Air Line
NOTE:
You
A.
must install an air pressure regulator (F) on the
gun air line to control air pressure to the gun. See
Fig. 2.
If your regulated air source does not have a filter
install an air filter (G) on the air line to ensure a dry
clean air supply to the gun. Dirt and moisture can
ruin the appearance of your finished workpiece.
See Fig. 2.
Use a 5/16 inch (7.9 mm) I.D. air hose to minimize
excessive pressure drop in the hose.
Connect the air hose (D) to the 1/4 npsm gun air
inlet (C).
2. Connect the Fluid Hose
NOTE:
Before

connecting the fluid line, blow it out with air
and flush it with solvent. Use solvent which is
compatible with the fluid to be sprayed.
Install a fluid regulator (L) on the fluid line to control
fluid pressure to the gun. See Fig. 4.
Filter the fluid line of coarse particles and sediment
to avoid clogging the fluid nozzle and causing
finishing defects.
