OPERATING INSTRUCTIONS AND REPLACEMENT PARTS
APPLICATION:
The Paasche “L” Sprayer has a wide variety of uses in applying
liquids of varied consistency. It is an ideal siphon type sprayer
for painting small items. It will handle paints, varnishes, bronzes,
lacquers, oils, cleaning solutions, disinfectants, foundry mold
compounds, etc.. It is one of the easiest sprayers to use and is
well constructed and simple to operate with no complicated
adjustments.
AIR SUPPLY:
Air pressure may range from 15 to 50 lbs., depending on the
material used and the type of work to be done.
1. Stipple and granulated effects require 15 to 25 lbs. air
pressure depending upon consistency of material used.
2. Air capacity of tips range from 1/2 to 6 C.F.M. @ 50 PSI
depending on the size of tip and the amount of air
pressure used.
INTERCHANGEABLE TIPS:
Four sizes of air and fluid tips are available. The “L” Sprayer is
normally supplied with an L-2 Tip unless otherwise specified.
1. For average use, the fluid tip should be adjusted to the
center of the air tip when “L” Sprayer is assembled.
2. For finer atomization and smaller spray turn fluid tip below
center of air stream.
3. After proper adjustment is made, the L-10 Locknut should
be tightened so that adjustment will not change.
CONNECTIONS:
Before connecting air hose to air inlet at the back of handpiece, blow
out the hose to remove any accumulation of dirt or foreign matter.
1. Air connection is 1/4" pipe thread. Either 3/16" or 1/4" inside
diameter air hose with 1/4" couplings should be used.
OPERATIONS:
The “L” Sprayer Handpiece should be inserted into L-210 Clamp
Block to the extreme forward position and locked by tightening L-
58 Lock Thumb Screw.
1. Material should be mixed thoroughly to slightly lighter
consistency than recommended for ordinary sprayers.
2. Materials should be strained through a cloth or wire mesh
strainer before filling cup.
3. To operate sprayer, pull back on the trigger.
4. Adjust fluid tip to give size of spray as explained above.

OPERATIONS CONTINUED:
Before beginning to paint, the operator should practice spraying
to acquire familiarity with the sprayer and control of spray.
1. To insure uniform application apply as light a coat as
possible, increasing the thickness with additional thin
layers of paint.
2. Each stroke should blend uniformly into the previous
stroke without runs or sags.
3. Spray full length of object to be coated releasing trigger at
the end of each stroke.
4. For average work the tip of the sprayer should be held 3
to 6 inches from the surface being painted.
FINISH:
A smooth finish is assured when the spray is properly adjusted
and the operator has acquired control of its application.
1. A rough or stipple finish is caused by air pressure that is
too low or restricted flow of air.
2. Rough finish will be obtained when sprayer is held too far
from the working surface.
3. A wet or sagging finish is caused by too much material
being applied or material being too thin.
CARE AND CLEANING:
Always clean the “L” Sprayer thoroughly after use.
1. The fluid tube should be cleaned with solvent siphoned
through the tip after painting operation is finished.
2. Never use alkali solutions for cleaning as they will
eventually destroy the aluminum parts.
3. Air and fluid tips must be kept clean at all times to insure
perfect atomization and a perfect pattern.
4. Sharp instruments should not be used in cleaning tips as
they will destroy or distort the openings.
