WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
To reduce the risk of fire, explosion, or
electric shock:
• The power source conduit is not an
adequate ground for the system.
The unit must be grounded to either the
building ground or a true earth ground.
• A qualified electrician must complete all
grounding and wiring connections and
check the resistance.
• Refer to your local code for the requirements for a
"true earth ground" in your area.
• Also read and follow the warnings on page 6.

Snuff-Back
Snuff-back is created when the needle is pulled back
through a restrictive ring before it closes against the
carbide seat.
For maximum snuff-back, leave the ring in place.
For maximum flow with less snuff-back, remove the ring.
For additional snuff-back, use a quick exhaust valve
(104661) on the "open" air port.
Nozzle selection and gun movement also effect fluid
cut-off characteristics.
