paint, cause overspray, make cutting-in
difficult, and decrease sprayer
performance.
If the tip is the maximum rated size for
your sprayer, when it wears, it will exceed
the flow rate capacity of the machine. If
when using the maximum capacity tip
size the pump cannot keep up, then you
know that the tip is worn beyond
capacity.
CLEANUP
At the end of the day, the material in the
line should be recovered and the machine
thoroughly cleaned. This will avoid
material drying in the pump or hose.
CAUTION: Under no circumstances
allow material to dry in the pump. If
material dries in the pump and hose,
the pump will need to be completely
disassembled and rebuilt and the hose
will need to be discarded and replaced.
1. Relieve pressure in the system
according to the Pressure Relief
Procedure.
2. Remove the tip and tip guard and soak
in the appropriate solvent for the
material being used.
3. Rinse off the suction tube and place in
a bucket of the appropriate flushing
solvent fluid. Usually this will be water
(for water-based materials), mineral
spirits (for oil-based materials) or
lacquer thinner ( for lacquers). Special
flushing fluids may be required for
component materials or epoxies, etc.
4. To reclaim the material in the pump,
place the drain tube in the original
material bucket. With the priming
valve still in the open position, turn the
machine on and turn the pressure
control knob clockwise just enough to
run the pump. watch the material
discharging from the drain tube until
the material begins to thin. This
indicates that the flushing fluid is
beginning to pump out. Now transfer
the drain tube to the waste bucket and
continue to flush until clear flushing
fluid flows out.
5. Shut off the machine and back off the
pressure control knob to minimum.
Close the priming valve.
6. To reclaim the material in the line, with
the tip and guard removed, point the
gun into the material bucket and hold
the trigger open.
7. Place the waste bucket right next to
the material bucket.
8. Ensure that the pressure knob is in the
minimum position and turn the unit on.
9. With the trigger held open, slowly turn
the pressure knob clockwise to
increase the pressure just enough to let
the pump run.
10. Allow the pump to run and watch the
material discharging from the gun.
Allow the material to discharge until the
material begins to thin. This indicates
that the flushing fluid is coming up the
hose..
11. Without releasing the trigger, quickly
transfer the gun from the material
bucket to the waste bucket next to it.
WARNING: Do not release the gun
trigger during this process. If you
release the trigger, pressure will build in
the line and when you re-squeeze the
trigger there will be a splashback
hazard.
12. Keep the trigger held open and allow
the pump to run and watch the fluid
discharging from the gun. Allow the
fluid to discharge until all traces of
material are gone and pure flushing
fluid is coming out.
