Changing Materials
Grounding
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.
3A3653A
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.
See your sprayer manual for system grounding instructions.

Flush Before Using Equipment
Flush Before Using
Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Grounding on page 5.
Setup
NOTE: See Parts on page 10 for part references.
Install Applicator Air Nozzle (Air Spray)
1. Perform Pressure Relief Procedure, page 7.
2. Install air nozzle (13, 14, 15, 22) into applicator (1).
Pressure Relief
Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
3. Install retaining ring (18) over air nozzle. Tighten
retaining ring.
Install Applicator Fine Finish Kit
NOTE: Fine Finish spray is not recommended for high
viscosity materials or for materials subject to “packing
out”, such as mortar or cement mixes.

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.
8
Air bleeds from the applicator nozzle whenever the air
assist 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.
3A3653A
Repair
Air Spray Techniques
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.
Repair
Spool Valve Repair
2. Adjust fluid flow until material flow is adequate.
3. Adjust the applicator air assist needle valve to
achieve a uniform round spray pattern.
4. Consider the size of aggregate in the material and
the coarseness of the spray pattern. Larger nozzles
allow heavier patterns.
Before performing any maintenance or repair on
applicator, read all warnings and perform Pressure
Relief Procedure on page 7.
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.
Spool Valve Removal
When spraying small confined areas use the valve and
knob to make fine adjustments without adjusting the
pump.
2. Remove retaining ring (27) and bearing (26).
1. Remove screw (29) and handle (28) from spool
(24).
3. Remove spool (24) from housing (1).
Spool Valve Installation
Cleanup

before fluid begins to cure in applicator. Remove check
valve (20) 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.
NOTICE
Check valve (20) will be damaged if any object is
inserted into valve.
1. Apply grease to spool, o-rings and bearing and
inside of housing.
2. Assemble o-rings (25) onto spool (24).
3. Install spool in housing (1) and install bearing (26).
