stopped. Under no circumstances should the
spray gun be pointed at the operator or oth-
ers, in case the trigger is accidentally pressed
causing the high -pressure coating to spray
and injure someone. If the spray gun can still
be opened aer the trigger safety has been
locked, the small nut at the end of the draw
bar of the gun’s valve plug should be adjusted.
If the nozzle is blocked, it should be im-
mersed and cleaned with solvent, Or cleaned
carefully with a brush. Do not poke it with
hard things as this may damaging the nozzle.
5. If a rotating nozzle issued during spraying
process and the nozzle is slightly blocked, just
turn the handle 180 degrees and trigger the
spray gun, the dirt in the nozzle will be blown
o by the hydraulic pressure to the high-pres-
sure coating itself. If the nozzle is completely
blocked, the connecting nut of the nozzle has
to be slightly loosened. e handle can only
be turned aer the coating has been depres-
surized. If the handle is turned by force while
the coating is still pressurized, the handle is
easily damaged. While using standard nozzle
or rotating nozzle, a sealing ring has to be
placed at the joint of the nozzle and the spray
gun.
6. If the sprayer has worked continuously for a
long time and a severe ‘’ frosting ‘’ phenom-
enon has appeared inside and outside the
silencer, a water -separating air dryer can be
installed before the compressed air enters the
sprayer.
7. If the spraying operation is nished or will
not be used for a long periods of time, the
suction pipe should be pulled out of the
coating tank in time. e residual coating
in the coating pump, the suction pipe the
high-pressure hose and the spray gun should
be discharged by running the sprayer idly.
en the whole coating hydraulic loop in-
cluding the coating pump, the suction pipe,
the discharge valve, the high- pressure hose,
the high pressure spray gun and the nozzle
should be cleaned by running the sprayer idly
with dilution agent or solvent.
