Graco 965466 Manual De Usuario

The system pressure must be manually

relieved to prevent the system from starting or
spraying accidentally. Fluid under high
pressure can be injected through the skin and
cause serious injury.  To reduce the risk of an
injury from injection.  To reduce the risk of
parts, follow the Pressure Relief Procedure
whenever you:

•  are instructed to relieve the pressure,
• stop 

spraying,

•  check or service any of the system

equipment,

•  or install or clean the spray tips.

The pumps were tested with lightweight oil at the factory.
Before operating the pump, thoroughly flush the Hydra-Cat
H.P. to prevent contamination of your fluids.

Flush the mixer, hose and gun often enough to prevent
fluid from reacting or curing in them. Contact  your fluid
manufacturer for the effective pot life of the fluid you are
using.

1. Put the pump intake hoses into a 5 gallon (20 liter)

container of a compatible solvent. Refer to the fluid
manufacturer’s recommendations.

2. Start the pump as explained below.

3.

Do not install a spray tip yet. Hold a metal part of the
gun firmly to the side of a grounded metal pail. Using
the lowest possible air pressure to the air motor that
will activate the pump, trigger the gun into the pail.

1.  Lock the spray gun’s trigger safety.

2. Shut 

off 

ALL fluid supplies to the pump.

3.  Close the bleed-type master air valve.

4.  Unlock the spray gun’s trigger safety.

5.  Hold a metal part of the spray gun firmly to the side

of a grounded metal pail. Trigger the spray gun into
the pail to relieve pressure.

6.  Lock the spray gun’s trigger safety.

7.  Open the sampling valves, having a container ready

to catch the drainage.

8.  If you suspect that the spray tip or nozzle or the

hose is completely clogged or that pressure has not
been fully relieved after following the steps above,
follow this procedure: Very slowly loosen the tip
guard retaining nut or hose end coupling and relieve
pressure  gradually, then loosen completely. Now
clear the obstruction.

4.  When clean solvent comes from the spray gun,

release the trigger and carefully check all connections
in the system for leaks.

5.  Take the hoses out of the solvent, and trigger the gun

until all the solvent has been pumped out of the hoses.
Immediately turn off the bleeder-type master air valve.

1.  Close the bleed-type master air valve, and turn the air

regulator knob all the way out (counterclockwise).

2.  Turn on the main air supply.

3.  With the mixer manifold handle in the open position,

trigger the gun, slowly open the bleed-type master air
valve, and turn the air regulator knob clockwise until
the pump starts.

4.  Allow the pump to cycle slowly until all the air is pushed

out of the lines. Release the trigger. The pump will stall
against the pressure.

5.  The manifold handle controls fluid flow. With the lever

of the manifold in the open (down) position, base and
catalyst are supplied to the gun. To stop the flow,
move the handle to the closed (up) position.

Use the solvent valves to flush contaminants and mixed
fluids from the mixer manifold, hose and spray gun. Follow
the procedure provided with the mix manifold assembly.
