Operation
Prime the Pump
1. See Fig. 3. Remove the tip guard and spray tip
from the gun (106). Refer to the gun manual.
2. Close the pump air regulator (G), and bleed-type
air valves (B, E).
3. Connect the air line (A) to the air inlet swivel (H).
4. Check that all fittings throughout the system are
tightened securely.
5. Fill the pail (19) with fluid. Make sure the pail cover
(1) is fastened securely to the pail with the screw
knobs (20).
6. Close the fluid drain valve (F).
7. Hold a metal part of the gun (106) firmly to the side
of a grounded metal pail and hold the trigger open.
8. Open the bleed-type air valves (B, E). Slowly open
the pump air regulator (G) until the pump starts.
9. Cycle the pump slowly until all air is pushed out
and the pump and hoses are fully primed.
10. Release the gun trigger and lock the trigger safety.
The pump should stall against pressure.
11. If the pump fails to prime properly, open the drain
valve (F). Use the drain valve as a priming valve
until the fluid flows from the valve. Close the valve.
NOTE: When changing fluid containers with the hose
and gun already primed, open the drain valve (F) to
help prime the pump and vent air before it enters the
hose. Close the drain valve when all air is eliminated.
Agitator Operation (Models 232437 and
232449)
1. Slowly open the control valve (J) to start the
agitator (39). See Fig. 3.
2. Use the valve (J) to adjust the speed. Do not
operate the agitator too fast. If the fluid foams or a
vortex forms on the fluid surface, reduce the speed
of the agitator.
3. Refer to manual 306565 for further agitator operat-
ing instructions.
Install the Spray Tip
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
Relieve the pressure. Install the spray tip and tip guard
as explained in your separate gun manual, supplied.
The spray tip shapes the fluid into a fan pattern. The
orifice size determines the flow rate, and the orifice
shape determines the width of the fan pattern.
