Reversible Spray Tip

Always perform Pressure Relief Procedure before
adjusting spray tip position.
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 spray tip,
it can be reversed to quickly clean the spray tip.
See Unclogging Spray/Tip Guard Assembly
(page 14) for detailed instructions.

Maximum Pressure Setting
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 ina poor spraying 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.
See Choosing Pressure Control Knob Setting on
page 12 for recommendations on the setting for your
job.

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
flexible suction tube screen end forward (away from trig-
ger) as shown below and push firmly into place.
NOTE: If the sprayer is angled or tilted too far, the
flexible suction tube will lose contact with the material
and the sprayer will stop spraying.
