WARNING
Inhalation of certain chemicals can 
cause susceptible persons to have an 
allergic or asthmatic reaction.
Substantial or repeated inhalation of 
certain chemicals may cause respiratory 
disease, cancer, birth defects, or other 
reproductive harm. Control the chemical 
spray at the source where possible. Use 
good work practices, such as operating 
the unit so that the wind or operating 
process does not blow the spray back on 
the operator. Follow the 
recommendations of 
EPA/OSHA/NIOSH and occupational 
and trade associations with respect to 
proper usage. When the inhalation of the 
chemical being sprayed cannot be 
avoided, the operator and any 
bystanders may need to wear a 
respirator approved by NIOSH/MSHA 
for the type of chemical encountered. 
Consult the label of the chemical product 
being used.
WARNING
If you are unfamiliar with the risks 
associated with the particular chemical 
at issue, review the product label and/or 
material safety data sheet for that 
substance and/or consult the material 
manufacturer/supplier. You may also 
consult your employer, governmental 
agencies such as the EPA, OSHA and 
NIOSH and other sources on hazardous 
materials. The state of California and 
some other authorities, for instance, 
have published lists of substances 
known to cause cancer, reproductive 
toxicity, etc.
Operating instructions
WARNING
Never spray in the direction of humans, 
animals or property which might be 
injured or damaged by spray formula.
Pay attention to the direction of the wind, 
i.e., do not work against the wind. When 
spraying, stand so that the wind does 
not blow towards you or bystanders.
Keep children and pets away from areas 
that have just been sprayed. After the 
use of some chemicals, especially 
agricultural pesticides, a notice must be 
posted on the treated area that a 
"Restricted Entry Interval" (REI) is in 
effect. See the product’s label and any 
applicable governmental regulations.
DANGER
After Finishing Work
Always release the pressure out of the 
pump and the pressure chamber after 
finishing work. To release the pressure, 
keep the trigger valve depressed without 
operating the hand lever until there is no 
more air, liquid or mist coming out of the 
nozzle. Avoid breathing in the mist which 
is released.
Always wash thoroughly with soap and 
water after spraying or handling 
chemicals. Shower immediately, and 
wash all protective clothing separately. 
Follow any additional recommendations 
of the chemical manufacturer. 
Always clean dust and dirt off the 
backpack sprayer.
WARNING
Empty, rinse and clean the container 
and sprayer assembly after each use. 
This helps to prevent the solution from 
crystallizing, which could later cause 
clogging and chemical damage to the 
unit. In addition, residual chemicals may 
have undesirable effects during 
subsequent spraying with a different 
type of chemical (e.g., residual herbicide 
may damage or kill plants being sprayed 
with a pesticide).
Disposal of contaminated rinse should 
be in accordance with applicable 
ordinances. Observe the precautionary 
instructions of the chemical 
manufacturer.
Do not store sprayer under pressure or 
with spray solution in the container.
Your backpack sprayer is 
not insulated against 
electric shock. To reduce 
the risk of electrocution, 
never operate this back-
pack sprayer in the 
vicinity of any wires or 
cables (power, etc.) 
which may be carrying 
electric current. Do not 
spray on or near electri-
cal systems.
