Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Close the air regulators (E).
2. Close the supply pump’s bleed-type air master valve
(B, required in system).
3. Open the dispensing valve (G) until pressure is fully
relieved.
NOTE: If you suspect that the dispensing valve, exten-
sion, or grease fitting coupler is clogged, or that pres-
sure 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 air master valve (B). Open the dis-
pensing valve (G), and slowly open the air regulator (E)
until the pump is running smoothly. After all the air is
purged, close the dispensing valve. The pump will start
and stop 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 you are finished using the pump for the day
always follow the Pressure Relief Procedure.
Maintenance
The accessory air line oiler (D) provides automatic air
motor lubrication. Four daily manual lubrication, discon-
nect the air hose, place about 15 drops of light machine
oil in the air inlet, reconnect the hose, and turn on the air
supply to blow oil into the motor.
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 the fluid being
pumped. A dry pump quickly accelerates to a high
sped and may damage itself. If your pump acceler-
ates quickly or is running too 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 the 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.
