SPRAYER CALIBRATION
Calibration of Sprayer for 9 Foot Wide Effective at 5 mph for Large Areas
Setting the sprayer application rate for 1 quart per 1000 sq. ft. at 5 mph and
9 foot wide
effective spray swath.
1. Put a few gallons of WATER in the tanks.
Water only no chemicals.
2. Start engine, set the engine speed to full throttle. The pump will now be operational.
3. Place a container under the
full
spray nozzle to catch the water.
4. Set the pump pressure using the pump pressure control knob on the control console. With all of the spray
control handles off, turn the knob in for more pressure or out for less pressure. Start with the pressure set at
40 PSI. This is an approximate setting to begin the process.
5. Time your unit to see how long it takes to travel
111 feet
(this should be around 15 seconds). With a 9 foot
wide spray it takes 111 feet for the unit to cover 1000 sq. ft.
6. Open the full spray control (far right red lever) for 60 seconds (4 times the 15 second speed) and measure
the amount collected at the full spray tip. Divide by 4 and this will give you the rate for 1000 sq. ft. (at 9 foot
wide and 5 mph).
7. If the amount is less than 1 quart per 1000 sq. ft. you will need to increase the pressure (turn the pressure
knob clockwise). More than 1 quart you will need to decrease the pressure (turn the pressure knob counter
clockwise). Setting the pressure with the nozzle spraying will give a more accurate setting.
8. Run the test again and continue until you get to the 1 quart per 1000 sq. ft. application rate.
9. Check the width of the spray pattern. To do this, spray the unit on a paved area for about one minute or until
the area is very wet. Measure the width of the spray pattern. It should be about 2 feet wider than the effective
9 foot swath or 11 to 12 foot. You do want a little extra width for an effective overlap of the next pass. If the
pattern is not wide enough you can move the nozzle up a little to increase the width. If the width is too wide
you can aim the nozzle down a little more to decrease the width.
Calibration of Sprayer for 6 Foot Wide Effective at 5 mph for Smaller Areas
Setting the sprayer application rate for 1 quart per 1000 sq. ft. at 5 mph and
6 foot wide
effective spray swath.
1. Put a few gallons of WATER in the tanks.
Water only no chemicals.
2. Start engine, set the engine speed to full throttle. The pump will now be operational.
3. Place a container under the
full
spray nozzle to catch the water.
4. Set the pump pressure using the pump pressure control knob on the control console. With all of the spray
control handles off, turn the knob in for more pressure and out for less pressure. Start with the pressure set
at 15 PSI. This is an approximate setting to begin the process.
5. Time your unit to see how long it takes to travel
166 feet
(this should be around 23 seconds). With a 6 foot
wide spray it takes 166 feet for the unit to cover 1000 sq. ft.
6. Open the full spray control (far right red lever) for 92 seconds (4 times the 23 seconds speed)
and measure
the amount collected at the full spray tip. Divide by 4 and this will give you the rate for 1000 sq. ft. (at 6 foot
wide and 5 mph).
7. If the amount is less than 1 quart per 1000 sq. ft. you will need to increase the pressure (turn the pressure
knob clockwise). More than 1 quart you will need to decrease the pressure (turn the pressure knob counter
clockwise). Always set the pressure with the nozzle spraying for a more accurate setting.
8. Run the test again and continue until you get to the 1 quart per 1000 sq. ft. application rate.
9. Check the width of the spray pattern. To do this, spray the unit on a paved area for about one minute or
until the area is very wet. Measure the width of the spray pattern. It should be about 2 feet wider than the
effective 6 foot swath or 8 to 9 foot. You do want a little extra width for an effective overlap of the next pass.
If the pattern is not wide enough you can move the nozzle up a little to increase the width. If the width is too
wide you can aim the nozzle down a little more to decrease the width.
