IDENTIFYING TIP SIZES.
►
To identify tip sizes, use the following formula
►
A 517 tip size will be used in this example
►
The first digit multiplied by two represents the
size of the spray pattern when spraying 12” (30
cm) away from the work surface: 5 x 2 = 10”
(25 cm) spray pattern
►
The second two digits
represent the diameter of the orifice on the tip:
17 = 0.017” (0.43 mm) orifice
►
Worn spray tips
will adversely affect the spray pattern and result
in reduced production, poor finish, and wasted
material ►Replace worn tips immediately.
CLEANUP.
►
Maintaining a clean airless gun is important to
ensure trouble-free operation
►
Flush the airless
gun after each use and store in a dry location
►
Do not leave the airless gun or any of its parts
in water or solvents.
CLEANUP INSTRUCTIONS FOR USE WITH
FLAMMABLE SOLVENTS.
►
Always flush airless gun preferably outside
and at least one hose length from spray pump
►
If collecting flushed solvents in a 4 liter
metal container, place it into an empty 20 liter
container, then flush solvents
►
Area must be
free of flammable vapors
►
Follow all cleanup
instructions
►
The sprayer, hose and airless
gun should be cleaned thoroughly after daily
use
►
Failure to do so permits material to cake,
seriously affecting the performance of the unit
►
Always spray at minimum pressure with the
tip and tip guard removed when using mineral
spirits or any other solvent to clean the sprayer,
hose or airless gun
►
Static electricity buildup
may result in a fire or explosion in the presence
of flammable vapors
►
Hold the airless gun firmly
against a metal container while flushing.
