Preparation
Compressor Break-in
The
first time you use the system, run the compressor
under no load to break it in, improve performance and
lengthen its life.
1.
Connect the air hose to (A) and the gun to the
other end of the hose. Open gun air valve (423)
and turn air restrictor valve (424) all the way to the
+ position. See Fig. 2 and 9.

Hose Size and Lengths
The
system comes with a hose set consisting of a 1 in.
ID x 25 ft (25 mm x 7.6 m) fluid hose and a 3/8 in. ID
air hose. The 1 in. hose set includes an adapter hose
between the gun and main hose. See parts, page 22.
Use the shortest length possible when spraying. In
creasing hose length decreases sprayer performance.
Do not use more than 75 ft (23 m) of fluid hose.

damage the unit.
Do not use any solvent-based materials. Use
only water-based materials.
Use only simulated acoustic and gypsum-based
wall texture materials in this system.
Do not spray cementious materials, which will
damage the pump.
Proper material mixture is essential. The pump
won’t operate if the material is too thick.
Mix material in a separate container and pour into the
hopper for best results.
Slowly add one bag of texture material to clean water
as instructed on the bag instructions. Agitate to a
smooth, lump-free consistency. Thin the material as
needed before pouring it into the hopper. For the
best results, do not use partial bags of material.
