IDENTIFYING TIP SIZES.
►
To identify tip sizes, use the following formula
►
A 517 tip size will be used in this example
►
The rst 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 orice on the tip:
17 = 0.017” (0.43 mm) orice
►
Worn spray tips
will adversely a󰀨ect the spray pattern and result
in reduced production, poor nish, 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

►
Area must be
free of ammable vapors
►
Follow all cleanup
instructions
►
The sprayer, hose and airless
gun should be cleaned thoroughly after daily
