3. Attach the flow calibrator bottle to the wand:
a. Remove the nozzle, cap and
filter from the spray wand.
b. Mount the flow calibrator
cover to the spray wand.
c. Reinstall the nozzle, filter
and nozzle cap.
d. Screw the flow calibrator
bottle into the cover.
4. Using the flow calibrator bottle:
a. Operate the pump handle to
maintain spray system pres-
sure as you would when
applying chemicals.
b. Hold the wand at your normal working position and spray
into the bottle while walking the distance identified in step 2
above.
c. Place the bottle on a level surface and observe the liquid
level visible through the side of the bottle. Match the liquid
level to the l/acre (liter per acre) scale on the calibration
bottle.
d. Multiply the l/acre (liter per acre) reading identified in
step 4-c by .264 to determine your application coverage rate
in gallons per acre.
e. Empty the bottle contents back into the sprayer tank.
NOTE:
For improved accuracy in calibrating your application coverage,
repeat steps 4-a through 4-e and average the results.
1. Hold the wand
at the working
height and spray
a test pattern to
measure the appli-
cation band width.
2. Based on the band
width, identify from the
table below the walking
distance required to calibrate
the sprayer.
Carefully read the labels on chemical contain-
ers prior to use. Chemicals are classified in four
categories of toxicity:
■ Category I, High Toxicity, Red label
■ Category II, Moderate Toxicity, Yellow label
■ Category III, Low Toxicity, Blue label
■ Category IV, Light Toxicity, Green label
There are unique handling recommendations
for each category, and you should familiarize
yourself with them.
Always wear clothing and safety equipment that
will provide appropriate protection against the
materials you are handling. Equipment may
include, but not be limited to:
■ Long sleeve shirt
■ Impermeable apron or coverall
■ Impermeable gloves and boots
■ Wide-brim hat
■ Protective mask equipped with
appropriate filters
Do not eat, drink, or smoke while handling
chemicals or while you are spraying. Always
handle chemicals in a well ventilated area while
wearing appropriate protective clothing and
safety equipment. DO NOT STORE OR TRANS-
PORT CHEMICALS WITH FOOD OR MEDI-
CINES, AND NEVER REUSE A CHEMICAL
CONTAINER FOR ANY OTHER PURPOSE.
Keep chemicals out of the reach of children,
animals, or other unauthorized people. When
not in use, store chemicals in a safe place. Never
blow through nozzles, valve, pipes or any other
component by mouth!
When handling chemicals and when spraying,
make sure you are operating in accordance with
local, state, and federal environmental protection
rules and guidelines. Do not spray in very hot
or windy conditions. DO NOT POLLUTE THE
ENVIRONMENT!
After spray application, take a thoroughly cleans-
ing shower using plenty of water and soap, then
change into clean clothes. Protective clothing
and safety gear should also be cleaned after each
use. IN CASE OF EXPOSURE TO DANGER-
OUS CHEMICALS, seek a physician immedi-
ately and be prepared to provide the label from
the chemical container.
