Reversible Spray Tip
In the event that particles or debris clog the spray tip,
this sprayer is designed with a reversible spray tip that
can be used to quickly and easily clear the particles and
resume spraying as quickly as possible.
• Always point the reversible spray tip
forward when spraying.
• When particles or debris get caught in the tip, it can
be reversed to quickly clean the tip.
• See Unclogging Spray/Tip Guard Assembly
(page 14) for detailed instructions.
Pressure Control Knob
• To reduce overspray, always spray at lowest pres
sure that results in an acceptable spray pattern.
• Spray test pattern and adjust pressure to get
desired coverage.
• With some materials, if pressure is set too low, no
material may spray out. Turn pressure control knob
up.
• Thin materials sprayed at high pressure settings
may cause the sprayer to enter an operational mode
designed to protect it from overheating. This mode
is noticeable by the sprayer sounding like it is slow
ing down and will result in a poor spray pattern.
To exit this mode, turn pressure control knob
down to lowest pressure setting that results in
an acceptable spray pattern.
• If spraying in low pressure range, there may not be
enough pressure to clear the plug. Turn pressure
control knob up to clear the plug.
Flexible Suction Tube
This sprayer comes with a flexible suction tube for
multi-directional spraying without adjustment.
To ensure proper function of flexible suction tube, orient
as shown. Make sure tab from sprayer is aligned with
groove from flexible suction tube and firmly push into
place.
NOTE: If the sprayer is angled or tilted too far, the flexi
ble suction tube will lose contact with the material and
the sprayer will stop spraying.
Always perform Pressure Relief Procedure before
adjusting spray tip position.
