English During Operation Holding and Controlling the Backpack Sprayer The backpack sprayer is operated with the right hand on the trigger valve and the left hand on the hand lever. The backpack sprayer is carried as a backpack. Warning! Adjust carrying harness to suit your size before starting work. In order to keep the container upright and reduce the risk of spillage, do not bend at the waist. Bend only at the knees and support yourself as required to ensure proper balance. Remember that a sprayer filled with liquid has a significant amount of weight. Use caution when bending, leaning or walking. Warning! To reduce the risk of injury from loss of control, never work on a ladder, in a tree or on any other insecure support. Working Conditions Operate your backpack sprayer only in a well-ventilated area. Operate it under good visibility and daylight conditions only. Work carefully. 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! 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. Never spray in the direction of humans, animals or property which might be injured or damaged by spray formula. 6 SG 20
