Operation
Never exceed 100 psi (7 bar, 0.7 MPa) air input
pressure to the pump, to reduce the risk of
component rupture which can cause serious bodily
injury, including injection or splashing of fluids in the
eyes or on the skin and to avoid damage to the pump.
Starting and Adjusting the Pump
1. Open the fluid supply shut off valve and the system
drain valve.
2. Open the bleed-type master air valve (C).
3. Slowly open the air regulator (D) until the pump
starts to cycle - about 40 psi (2.8 bar, 0.28 MPa).
4. Allow pump to cycle slowly until all air is purged
from the lines.
NOTE: The lines are purged when the fluid emitted
from the drain valve is flowing in a steady stream.
5. With the lines purged, close the system drain valve
(M).
NOTE: The pump will stall against pressure.
•
With the pump and lines primed and with adequate
air pressure and volume supplied, the pump will
start and stop as supply demands or until the
bleed-type master air valve (C) is shut off.
NOTICE
Always use the lowest air pressure necessary to give
you the result you want. Higher pressure causes pre-
mature pump wear.
•
If your pump accelerates 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 lines
with fluid or flush and leave filled with compatible
solvent.

NOTICE
Never allow the pump to run dry of fluid being pumped.
A dry pump will quickly accelerate to a high speed, pos-
sibly damaging itself.
•
Be sure to eliminate all air from fluid system to pre-
vent corrosion.
NOTICE
Water or even moist air can cause pump corrosion. To
prevent corrosion, NEVER leave the pump filled with
water or air. After normal flushing, flush the pump again
with water or mineral spirits or oil-based solvent,
relieve pressure (see Pressure Relief Procedure,
below) and leave the mineral spirits in the pump.
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 pumping and before
cleaning, checking, or servicing the equipment.
1. Shut off air to the pump.
2. Close the bleed-type master air valve.
3. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Keep you
hands away from the end of any drain valve when
opening it.
4. Leave drain valve(s) open until you are ready to
pump again.
5. If you suspect the hose is clogged or plumbing line
is clogged or that pressure has not been fully
relieved after following the steps above, VERY
SLOWLY loosen the hose or line end coupling to
relieve pressure gradually, then loosen completely.
Clear the obstruction.
