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 Your backpack sprayer is not insulated against electric shock. To reduce the risk of electrocution, never operate this backpack sprayer in the vicinity of any wires or cables (power, etc.) which may be carrying electric current. Do not spray on or near electrical systems. English 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. SG 51, SG 71 7
