Sprayers

Paasche L#1

Applications
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. Forfineratomizationandsmallersprayturnfluidtipbelow center of air stream.
3. Afterproperadjustmentismade,theL-10Locknutshould be tightened so that ad justment 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.
5. Before beginning to paint, the operator should practice spraying to acquire familiarity with the sprayer and control of spray.
6. To insure uniform application apply as light a coat as possible, increasing the thickness with additional thin layers of paint.
7. Each stroke should blend uniformly into the previous stroke without runs or sags.
8. Spray full length of object to be coated releasing trigger at the end of each stroke.
9. 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.
