Unclogging Spray Tip/Guard Assembly

Aiming Sprayer
Aim spray tip of sprayer at bottom edge of previous stroke,
overlapping each stroke by half.
Spray Pattern Quality
A good spray pattern is evenly distributed as it hits the sur-
face. Adjust pressure control knob so pressure is just high
enough to spray without “tails”. If tails persist at highest
pressure setting, a smaller spray tip is needed to spray the
material or material may need to be thinned.
Unclogging Spray Tip/Guard
Assembly
1. To unclog spray tip clog, engage trigger lock and put
prime/spray valve UP to release pressure.
2. Reverse spray tip to UNCLOG position. Turn pressure
control knob to maximum pressure setting.
3. Aim sprayer at waste area, disengage trigger lock, and
put prime/spray valve DOWN to spray position. Pull
trigger to clear clog.
4. Engage trigger lock. Put prime/spray valve UP to
release pressure and rotate spray tip back to SPRAY
position.
5. Disengage trigger lock, put prime/spray valve DOWN
to spray position, and resume spraying.
6. If spray tip is still clogged, you may have to repeat
steps 1 - 5 and rotate the spray tip from SPRAY to
UNCLOG several times. Repeat step 1 to release
pressure, remove and clean spray tip filter, or replace
with new spray tip assembly.
NOTE: Spray tip filter assembly is reverse-threaded:
Turn left (or counter-clockwise) to install.
Turn right (or clockwise) to remove.
7. When obstruction is cleared, engage trigger lock and
rotate spray tip back to SPRAY position.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing fluid
and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
