Stihl BG 56 C-E BG 66 L BG 86 SH 56 SH 86 Instruction Manual

To start your Stihl BG 56 C-E, first ensure the blower is on a flat surface. Set the choke to the start position, press the fuel pump bulb until the fuel is visible, and pull the starter grip until the engine fires. Move the choke to the run position and pull the starter grip again until the engine runs.
If your Stihl BG 86 won't start, check the fuel level and quality, inspect the spark plug for damage or wear, ensure the air filter is clean, and verify that the ignition switch is in the correct position. If issues persist, consult a professional technician.
For optimal performance, clean the air filter of your Stihl SH 56 after every 10 hours of operation. If operating in very dusty conditions, clean more frequently to prevent engine damage.
Stihl recommends using a high-quality 89 octane or higher unleaded gasoline mixed with Stihl 2-cycle engine oil at a ratio of 50:1 (gasoline to oil) for the BG 66 L. Avoid using fuels with more than 10% ethanol content.
Regular maintenance for the Stihl SH 86 includes cleaning the air filter, inspecting the spark plug, checking the fuel system for leaks, and ensuring that the blower tubes are clear of debris. Perform a thorough inspection every 25 hours of use.
If your Stihl BG 56 C-E is losing power, check the air filter for dirt or blockage, inspect the spark plug for fouling, ensure the fuel is fresh, and examine the exhaust for blockages. Clean or replace components as necessary.
While the Stihl BG 86 is powerful, it is most effective on dry leaves. Wet leaves are heavier and may clog the blower. If necessary, use the blower at a reduced speed and clear the nozzle frequently to prevent blockages.
To convert the Stihl SH 56 from blower to vacuum mode, first ensure the engine is off and cooled. Remove the blower tube and attach the vacuum tube and bag. Follow the manufacturer's instructions for securing the components properly.
Always wear protective eyewear and hearing protection when operating the Stihl BG 66 L. Ensure the work area is clear of bystanders, especially children and pets. Do not operate the blower indoors or in confined spaces due to exhaust fumes.
To store your Stihl blower for the winter, empty the fuel tank and run the engine until it stops to clear the carburetor. Clean the blower thoroughly and store it in a dry, cool place. Consider removing the spark plug and adding a few drops of oil to the cylinder to prevent corrosion.
