Operation – Important Safety Information Sprayer leak Bodily chemical contact Poisoning by ingestion or inhalation Chemical spills In the event that the sprayer develops a leak while spraying chemicals, you must immediately stop spraying. Turn off power to the sprayer and follow the directions below, as applicable. Personal contamination can occur when chemicals splash, spill, or spray directly onto a person. 1.
Operation – Preparing the Sprayer for Each Use If the sprayer has been used previously, it must be prepared BEFORE EACH SUBSEQUENT USE. WARNING Read instructions below carefully for inspecting and preparing the sprayer. Damaged or clogged equipment could result in leaks or uncontrolled spray. Leaks could result in injury to the operator or bystanders from chemical exposure, or cause damage to the environment. Important safety rules: • • • Power off.
Operation – Preparing the Sprayer for Each Use Step One: Assess wind conditions and clear work area. Before you decide to spray, you must determine whether wind conditions are suitable. You must also restrict access to the work area to ensure the safety of bystanders. WARNING Do not spray if wind speeds are greater than 4 MPH or if there are bystanders in the intended spray area. 1. Assess wind speed Assess weather conditions to ensure that it is not too windy to spray.
Operation – Using the Sprayer Step Two: Fill the sprayer. WARNING ALWAYS wear personal protective equipment as directed on the chemical label when handling pesticides. Long pants and sleeves, chemical resistant gloves, and eye protection are strongly recommended. Additional protective gear may be required depending on the particular pesticide. The motor surface temperature can reach temperatures over 70° C. In order to avoid scalding, wear gloves during operation of the sprayer.
Operation – Using the Sprayer 7. Check drain cap Before filling tank, ensure drain cap is securely tightened. Drain cap 8. Fill tank Add pesticide to tank through fill cap: a) Confirm the chemical/water dilution ratios specified on the chemical label. b) Determine chemical and water volumes needed for the planned application, taking into consideration that maximum tank capacity is 21 gallons for Model # 282780. 31 gallon tank capacity for Model # 282785.
Operation – Using the Sprayer Step 3: Operate the sprayer. WARNING ALWAYS wear personal protective equipment as directed on the chemical label when spraying. Long pants and sleeves, chemical-resistant gloves, and eye protection are strongly recommended. Additional protective gear may be required depending on the particular pesticide. 1.
