Calibrating the SprayerSafety Precautions

Carefully read the labels on chemical containers 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 TRANSPORT CHEMICALS WITH FOOD
OR MEDICINES, 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 ver y hot
or windy conditions. DO NOT POLLUTE THE
ENVIRONMENT!
After spray application, take a thoroughly
cleansing 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
DANGEROUS CHEMICALS, seek a physician
immediately and be prepared to provide the
label from the chemical container.
(Requires optional flow calibrator bottle, P/N 646901)
1. Hold the wand at
the working
height and spray
a test pattern to
measure the
application band width.
2. Based on the band width,
identify from the table below
the walking distance required
Band
Width
to calibrate the sprayer.
Band width 1.6 ft 2.3 ft 3.3 ft 4.0 ft 5.0 ft
0.5m 0.7m 1.0m 1.2m 1.5m
