9. Adjustments to the spray pattern can be made with the nozzle at the end of the
spray wand. Turn the nozzle counterclockwise to narrow the spray pattern, and
clockwise to broaden the spray pattern.
10. The sprayer has an adjustable pressure relief valve (See Fig. 8) on the block assembly.
You may need to vary the pressure according to the viscosity of the material you are using.
Thinner liquids tend to need more pressure to assure a good coverage pattern. It is
recommended to use a lower pressure setting for certain liquids, especially with higher solids,
as high pressures can be problematic.
CAUTION: NEVER EXCEED 100 PSI (S151) or 150 PSI (S201)
11. While not spraying, turn the bypass valve on to remove unnecessary pressure from the
pump. Turning off the engine when not spraying will prolong the life of the pump.
12. The return hose may be used to check for any sediment remaining lodged at the bottom of
the drum. If none is detected, the suction hose can be lowered completely into the drum. If
sediment remains after several minutes of spraying, it may be necessary to remove the sprayer
and stir the material manually.
