English Bayonet Fuel Filler Cap Never use a tool to open or close the bayonet fuel filler cap, as this could damage the cap and cause fuel to leak out. The bayonet fuel filler cap must be closed with care after refuelling. Filling the Container Warning! Tighten all connections and check to be sure the hose is securely attached and in good condition. Keep the valve lever on the control lever closed. Before using the power tool with chemicals, fill it with fresh water to assure that you have it properly assembled and practice spraying. Also, check for any leaks at this time. When thoroughly familiar with the power tool operation, follow normal operating procedures. Fill your power tool in well-ventilated areas, outdoors. Warning! Do not use: - flammables in the mistblower, which can explode causing serious or fatal injury; - caustic or corrosive materials in the mistblower, that could result in damage to the unit; - liquids with a temperature above 120° F (50° C) to avoid scalding and damage to the unit. To fill the container, place the power tool on a level surface. To reduce the risk of contaminating the surrounding environment, be careful not to overfill the container with chemical solution. To reduce the risk of injury, do not fill the unit while wearing it on your back. If you fill the container with a hose attached to a central water supply, be sure the end of the hose is out of the solution to reduce the risk of backflow, i.e. the chemicals being sucked into the water supply in the case of a sudden vacuum. Calculate the correct amount of chemical solution so that it is used up at one time, with no extra solution left in the tank. After filling, fit the container cap and tighten it down firmly. Warning! Check for leakage while refilling and during operation. A leak from the container or a loose fitting could soak your clothing and come into contact with your skin. Before Starting Warning! Always check your power tool for proper condition and operation before starting, particularly the throttle trigger and setting lever with stop position. The throttle trigger must move freely and always spring back to the idle position. Never attempt to modify the controls or safety devices. Warning! To reduce the risk of leakage and skin contact with chemicals, check that the container cap and all connections in the path of the spray are tight, and be sure the hose is securely attached and in good condition. Keep the valve lever closed. Warning! Never operate your power tool if it is damaged, improperly adjusted or maintained, or not completely or securely assembled. Warning! Check that the spark plug boot is securely mounted on the spark plug - a loose boot may cause arcing that could ignite combustible fumes and cause a fire. Keep the control handle clean and dry at all times; it is particularly important to keep it free of moisture, pitch, oil, fuel mix, grease or resin in order for you to maintain a firm grip and properly control your power tool. 8 SR 430, SR 450
