Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Close the air regulators.
2. Close the supply pump’s bleed-type master air valve
(required in this system).
3. Open the dispensing valve until pressure is fully
relieved.
If you suspect that the dispensing valve, extensions, or
grease fitting coupler is clogged, or that pressure has
not been fully relieved after following the steps above,
VERY SLOWLY loosen the coupler or hose end coupling
and relieve pressure gradually, then loosen completely
and clear the clog.
Startup and Adjustment
Open the bleed-type master air valve. Open the dis-
pensing valve and slowly open the air regulator until the
pump is running smoothly. After all the air is purged,
close the dispensing valve. The pump starts and stops
as the valve is opened and closed.
Use the air regulator (E) to control the pump speed and
fluid pressure. See F
IG. 2. Always use the lowest pres-
sure necessary to obtain the desired results.
When done using the pump for the day, always follow
the Pressure Relief Procedure at left.
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.
NOTICE
Never allow the pump to run dry of fluid being
pumped. A dry pump quickly accelerates to a high
speed and may damage itself. If your pump acceler-
ates quickly, or is running to fast, stop it immediately
and check the fluid supply. If the supply container is
empty and air has been pumped into the lines, prime
the pump and lines with fluid, or flush the pump and
leave it filled with a compatible solvent. Be sure to
eliminate all air from the fluid system.
