Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
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 dispensing and before
cleaning, checking, or servicing the equipment.
1. Close the bleed-type master air valve (A) (required
in the system) or female quick-disconnect coupler
(M).
2. Hold a metal part of the dispensing valve (J) firmly
to a grounded metal waste container and trigger
the valve to relieve the fluid pressure.
3. Open the drain valve (H).

Start Up and Adjustment

COMPONENT RUPTURE HAZARD
The maximum working pressure of each component
in the system may not be the same. To reduce the
risk of over-pressurizing any component in the
system, be sure you know the maximum working
pressure of each component. Never exceed the
maximum working pressure of the lowest rated
component in the system. Over-pressurizing can
result in rupture, fire, explosion, property damage,
and serious injury.
Limit the air to the pump so that no air line or fluid line
component or accessory is over-pressurized.
To determine the fluid output pressure using the air
regulator reading, multiply the ratio of the pump by the
air pressure shown on the regulator gauge. For
example:
6 (:1) ratio x 180 psi air = 1080 psi fluid output
6 (:1) ratio x 7 bar air = 42 bar fluid output
6 (:1) ratio x 0.7 MPa air = 4.2 MPa fluid output
The air motor exhaust coming out of the muffler
could contain harmful materials, such as oil,
anti-freeze, or some of the material being pumped.
Wear appropriate protective equipment when in the
work area to help prevent serious injury, including
inhalation of toxic fumes.
1. With the air regulator (C) closed, open the
bleed-type master air valves (A), or, if so equipped,
join the female quick-disconnect coupler (M) to the
male quick-disconnect pin fitting (L).
2. Open the dispensing valve (J) into a grounded
metal waste container, making firm metal-to-metal
contact between the container and valve,
3. Open the pump air regulator (C) slowly, just until the
pump is running. When the pump is primed and all
