Figure 14. Pump until clean solvent appears.
Warning: conductive metal containers must be used
when flushing flammable fluids through the system.
Always flush at low pressure with spray tip removed.
A metal part of the spray gun must be held firmly
against the grounded metal pail when flushing or
relieving pressure from the gun.
7) Pump solvent out by lifting both suction and return
hose out of the solvent. Turn pressure control to
minimum and open prime valve to release system
pressure. Lock trigger and cleanspray tip before re-
installing on gun.
Figure 15. Fluid is pumped out.
8) Follow above steps 1-7 using clean solvent to
completely flush unit.
9) If changing paint types, ie: latex (water base) to oil
base, you would have to flush unit with clean mineral
spirits using above steps 1-7. This would prepare the
pump for the oil base paint. Water would have to be
used as a last flush if changing from oil base paints to
latex.
CLEANING INSTRUCTIONS
10) Ensure pressure control is turned to minimum and
all pressure is released. Open prime valve. Turn
pump OFF.
11) Unthread gun handle from gun body to access gun
filter. Remove filter and brush clean with appropriate
solvent. Inspect filter for pinholes, plugging, or other
damage. Replace if required. Re-install with “double
lip” end pointing up into gun. Lightly grease handle
threads (petroleum jelly, auto grease) and re-install
firm hand tight. Brush exterior of gun clean.
12) Remove intake screen on metal suction tube and
brush clean, re-install.
13) Storing unit for more than 3 days. If unit was
cleaned with an oily paint thinner such as varsol, the
unit is now ready for storage (after step 14). If unit
was cleaned with water or a strong thinner (ie. lac-
quer thinner) pump varsol (or mineral spirits) through
the entire system by repeating step 8. If varsol is not
available, drain all the solvent out of the hose, gun,
and pump. (Tungsten carbide parts in the valves
will corrode if left in water for long periods of
time).
14) Coil up electrical cord and spray hose, inspecting
both for signs of damage. Suggested minimum coil
size for 1/4" paint hose is 18 inches.
DO NOT COIL PAINT HOSE TOO TIGHTLY. THIS MAY
CAUSE KINKS, WHICH WEAKEN THE HOSE. A
PAINT HOSE WITH KINKS OR OTHER DAMAGE
SHOULD BE CONSIDERED UNSAFE AND BE RE-
PLACED IMMEDIATELY.
WARNING: DO NOT CLEAN THE SPRAY GUN UN-
LESS THE PRESSURE HAS BEEN RELEASED FROM
THE SYSTEM. SEE PAGES 3 & 4 FOR FURTHER
PRECAUTIONS.
Warning!
