Prevent Prevent Pack out
To avoid "packing out" the pump or hose:
• Use the lowest pressure and largest nozzle size
that provides an acceptable spray pattern. This will
also result in seals and wear parts lasting much
longer.
• Do not use any more fluid hose than is necessary.
• Use an applicator with a rubber tip retainer that will
blow off if it plugs.

• Always have the atomizing air turned on at the
applicator (see Applicator manual 3A3244) before
and after spraying.
NOTE: If ball valve kit (17J703) has been installed, NOTE: NOTE:
do NOT use the valve to stall the pump. The pump
must be stopped first before the ball valve can be
closed.
Before Starting Starting Material Material Flow

Sprayer Sprayer Performance Sprayer Performance Performance
NOTE: NOTE: NOTE: The check valve (46) helps to improve pump
performance with highly compressible gypsum based
materials. For high density, Portland cement based
materials, the check valve (46) can be replaced with
1–1/2 NPT Nipple Fitting (121441) to reduce pressure
drop and improve performance.

Spraying

Spraying Spraying
1. Mix the Material, page
2. Prime with Material, page
• Do not allow pump to run without material
in the hopper. It can cause damage to the
pump seals.
• To prevent material curing in system, never
load material into a dry system. Always
prime system with water first. Loading
material into a dry system will cause the
material to stick to internal components
and cure causing damage and requiring
replacement of those parts.
• Failure to flush prior to material curing in the
system will result in damage to system and
may require replacement of all system parts
in contact with the material.
3. Open air ball valve (CB) on spray pole applicator.
See Applicator manual 3A3244.
4. Turn hydraulic pressure control (S)
counterclockwise to lowest pressure.
5. Verify that the main power disconnect (DD) is
ON.
