Warnings
Material Self-ignition
Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings and
material MSDS.
Changing Materials
NOTICE
Changing the material types used in your equipment
requires special attention to avoid equipment damage
and downtime.
• When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
• Always clean the fluid inlet strainers after flushing.
• Check with your material manufacturer for
chemical compatibility.
• When changing between epoxies and urethanes
or polyureas, disassemble and clean all fluid
components and change hoses.
4
Grounding
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Improper grounding can cause
electric shock. Grounding provides an escape wire
for the electric current.
Applicator: ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.

Air Spray
When Spraying
1. Set material flow (see sprayer instruction manual for
additional information).
2. Spray test pattern.
3. Turn air knob on and adjust, and/or select another
air nozzle, for desired pattern.
NOTE: Air continues to flow when handle is in off position to keep material out of air passages.
General Adjustments
The spray pattern can be adjusted by changing:
•
Tip (C) size
•
Fluid flow
•
Air flow, use needle valve (E)
The standard applicator adjustment is to fully open the
air assist valve (F) while adjusting the needle valve (E)
for the minimum air flow necessary for a good pattern.
332768B
Air bleeds from the applicator nozzle whenever the
applicator air valve (F) is open. Close the valve to stop
the air flow, if desired. Otherwise, the air valve can stay
open during priming. Air must be on prior to fluid flow.
Adjusting the spray pattern requires testing to balance
the fluid flow and the air to the applicator, and requires
the correct tip size.
Air Flow Valve Adjustment
To decrease air flow, turn valve knob (E) clockwise.
To increase air flow, turn valve knob (E) counterclockwise.
Check material and thin as needed to maintain the
proper consistency. The material may thicken as it sits
and could slow down application or affect the spray pattern.
Flush and dry applicator thoroughly at the end of each
use.

Spraying
Air Spray Techniques
Aligning Spray (Airless Spray)
1. Test the spray pattern on cardboard. Hold the applicator 6-18 in. (150-450 mm) from the surface. Use
this spraying distance for most applications.
2. Adjust fluid flow until material flow is adequate.
1. Perform Pressure Relief Procedure, page 6.
3. Adjust the applicator air assist needle valve to
achieve a uniform round spray pattern.
2. Loosen guard
retaining nut.
4. Consider the size of aggregate in the material and
the coarseness of the spray pattern. Larger nozzles
allow heavier patterns.
3. Align guard
(107) horizontally to spray a
horizontal pattern.
5. Overlap each stroke 50%. A circular overlapping
pattern may give the best results, and is obtained by
grasping the flex-head and swinging the head
around as the hose flexes.
When spraying small confined areas use the valve and
knob to make fine adjustments without adjusting the
pump.
(3) Horizontal
(4) Vertical
ti11909a
ti11908a
4. Align guard (107) vertically to spray a vertical pattern.
Clearing Clogs (Airless Spray)
Cleanup

before fluid begins to cure in applicator. Remove check
valve (215) and clean all residue from air passages.
Store in a dry location. Do not leave the applicator or
any parts in water or cleaning solvents.
1. Perform Pressure Relief Procedure, page 6.
2. Rotate tip (116) 180°. Open applicator into hopper
or onto ground to remove clog.
3. Rotate tip (116) 180° back to spray position.
NOTE: Check valve (215) will be damaged if any object
is inserted into valve.
Cleanup (Airless Spray)
Airless Spray
Thoroughly flush applicator after each work session
before fluid begins to cure in applicator. Remove check
valve (215) and clean all residue from air passages.
Store in a dry location. Do not leave the applicator or
