SQUEEGEE SP300 DUAL/SPRAY
APPLICATION – SPRAY BAR:
1.
Perform steps 1-4 from above.
2.
Open all 1/2” ball valves #42 on the spray bar #41.
3.
Start the machine in motion and slowly open spray bar valve #49.
Completely open the valve as you increase your forward motion speed.
You may need to increase the pump speed control valve #53 and
pressure control knob #52.
4.
Close spray bar valve #49 when you reach the end of the pass. Turn
around and re-open spray bar valve #49. When finished shut off the
pump controls and close all valves. While it is not necessary to water
flush the system after each use, you may want to as this keeps the spray
tips clear.
WATER FLUSH:
1.
Start with all valves closed.
2.
Open 3/4” ball valve #58.
3.
Turn on pump toggle switch #48. Open pump speed control valve #53
about three turns.
4.
To flush out the spray wand, open 3/4” ball valve #55. Open the lid on
the machine, place the wand in the tank and open the wand valve. It is
not necessary to run it till you see clear water as this is a waste.
However, you need enough water to push the sand out of the hose,
otherwise, it lays in the coils and plugs the hose.
5.
To flush the spray bar #41 open all spray bar 1/2” ball valves #42. Now
open spray bar valve #49. When finished shut off all pump controls and
close all valves. Always make sure you close 3/4” ball valve #58. While
there is a check valve #84 to prevent the sealer from flowing backward
into the water tanks, it must not be relied on to always close.
6.
This is a good time to remove the basket strainer lid #46 of the basket
strainer and clean out the strainer basket #44. Inspect the lid gasket #45
for tears.
