Operation
Pressure Relief Procedure
1.
Engage the trigger lock.
2.
Close the bleed-type master air valve to shutoff the
pump.
3.
Disengage the trigger lock.
4.
Hold a metal part of the gun firmly to a grounded
metal pail. Trigger the gun to relieve pressure.
5.
Engage the trigger lock.
6.
Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave
drain valve(s) open until you are ready to spray
again.
7.
If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after follow-
ing the steps above, VERY SLOWLY loosen tip
guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Clear
hose or tip obstruction.
Trigger Lock
Always engage the trigger lock when you stop spraying
to prevent the gun from being triggered accidentally by
hand or if dropped or bumped.
Startup
1.
Connect the suction kit (T) to the pump's fluid inlet,
and place the tube into the fluid supply.
2.
Close the air regulator (F) then open the pump's
bleed-type master air valve (E) to prepare the
pump’s power source.
3.
Hold a metal part of the gun (S) firmly to the side of
a grounded metal pail and hold the trigger open.
4.
Slowly open the air regulator until the pump starts.
5.
Cycle the pump slowly until all air is pushed out and
the pump and hoses are fully primed. Release the
gun trigger and lock the trigger safety latch. The
pump should stall against pressure when the trigger
is released.
6.
With the pump and lines primed, and with adequate
air pressure and volume supplied, the pump will
start and stop as the gun is opened and closed. In a
circulating system, the pump will speed up or slow
down on demand, until the air supply is shut off.
7.
Always use the lowest air pressure necessary to get
the desired results. Higher pressures cause prema-
ture tip/nozzle and pump wear. Use the air regulator
(F) to control the pump speed and fluid pressure.
8.
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a
high speed, possibly damaging itself.
Follow the Pressure Relief Procedure when-
ever you see this symbol.
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.
If your pump accelerates quickly, or is running too
fast, stop it immediately and check the fluid supply.
If the supply container is empty and air has been
pumped into the lines, refill the container and prime
the pump and the lines with fluid, or flush and leave
it filled with a compatible solvent. Be sure to elimi-
nate all air from the fluid system.
