always strain paint before use with a paint
strainer bag and regularly clean all filters
and strainers.
Replace tips before they become
excessively worn. Worn tips waste 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
ow 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 ushing
solvent uid. 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.
For Hopper equipped models: Place the
drain tube in the original material bucket
and open the priming valve. Now run the
machine at low pressure to pump all of the
material out of the hopper and into the
original material bucket. Once the hopper
is empty, shut the machine off. Wipe the
hopper with a rag and ll it with a sucient
quantity of the appropriate ushing solvent
uid.
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
