Stihl SR 430 Instruction Manual - Page 12

English To relieve vapor lock: - Press the manual fuel pump bulb at least 20 to 30 times - even if the bulb is already filled with fuel - to clear the vapor and send liquid fuel into the carburetor. Then start the power tool. For specific starting instructions, see the appropriate section of your instruction manual. - If the manual fuel pump bulb will not be filled, place the Choke Knob to the cold start position c and pull the starter cord until the engine runs. If the engine does not fire after 10 pulls in the cold start position c, place the Choke Knob to the warm start position o and start the engine in the warm start position o. - If your power tool will not restart, or if vapor lock occurs again, the power tool is being used in conditions too extreme for the fuel being used. Discontinue use and let the engine cool completely before attempting to start the power tool. 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 Operation 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 Check fuel system for leaks, especially the visible parts, e.g., filler cap, hose connections, manual fuel pump (only for power tools equipped with a manual fuel pump). Do not start the engine if there are leaks or damage - risk of fire. Have the power tool repaired by a STIHL servicing dealer before using it. 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. 10 SR 430, SR 450
