INJECTION AND HOT MATERIAL
HAZARDS
To reduce the risk of serious injury from
fluid injection or contact with hot material:
Lock the piston rod safety whenever you stop
dispensing.
Wear the appropriate protective clothing,
gloves, eyewear, facemask, and respirator.
Follow the startup procedure in the Graco Shot Foam
System manual. A general startup procedure is pro-
vided below, however, each application will differ in
some way. Always follow the specific recommenda-
tions of the system and material suppliers.
1. Adjust the fluid temperature.
Read the Graco Shot Foam System manual and
material supplier recommendations for the best
hose control temperature settings for your specific
application. Typical foams are designed to spray at
150 F (65 C).
2. Adjust the pump outlet pressure.
Read the Graco Shot Foam System manual and
material supplier recommendations. Typical pres-
sures are 400 to 500 psi (28 to 35 bar).
WARNING
COMPONENT RUPTURE HAZARD
Do not exceed the maximum working
pressure of the lowest rated system
component. This equipment has a 950
psi (66 bar) maximum working fluid pressure
and a 180 psi (12 bar) maximum working air
pressure. Exceeding these pressures can cause
component rupture, which can result in serious in-
jury or property damage.
