Check “Quick Couplers” for secure connection: Hose reel to unloader, Return line to tank
& Supply (suction) line on the bottom of the tank.
Open valves: Bypass valve (unloader) & Supply (suction) valve below tank.
Depress spray gun trigger during start-
up to allow for “Load Free” run-up.
Check sight glass on filter bowl during start-up. Air bubbles during operation may indicate
a cracked filter bowl or missing o-ring or gasket.
START UP
1.
Put 10 gallons of water into the sprayer tank. DO NOT ADD SPRAY YET!!!
TESTS
2.
Test the sprayer. It should have up to 800 PSI when spraying with the misting wand.
The bypass valve must be shut for this test.
TANK AGITATION
3.
The water in the tank should be agitating whenever the pump is on (but not spraying)
or when the ball valve is open.
LEAK INSPECTION
4.
Check for any leaks. Find the source of any and all dripping water. Be sure to
confirm that the filter is clean and that the filter bowl is tightly screwed on.
ADD SPRAY
5.
Additional water and spray may now be added to the tank. Any products that are
heavy solids may be added to the tank slowly. Additional water should be added to
the tank to keep the powder well diluted. Some sprays may also be harmful to the
pump seals if used at full strength. Check CAT pump manual for compatibility.
CLEAN UP
6.
Cleaning herbicide from the Sprayer: Use one quart of household ammonia per 60
gallons of water (1:240 ratio). Stir well!! Start the pump and run the unit until the
ammonia fills the MD83 hose and wand. Allow to stand for 24 hours.
RINSING
7.
Flush with fresh water. Triple rinse with clear water. Winterize for cold weather.
