To start the McCulloch ST 61E Blower, ensure it is on a flat surface. Press the primer bulb several times until fuel is visible inside. Set the choke lever to the full choke position, pull the starter rope until the engine tries to start, then set the choke to half position and pull again until it starts.
Use a mixture of unleaded gasoline and a high-quality 2-stroke oil at a ratio of 50:1. Ensure that the mixture is well-blended before filling the fuel tank.
If the blower is not starting, check the fuel mixture, ensure the spark plug is clean and properly connected, verify that the air filter is not clogged, and ensure the choke is in the correct position.
Regular maintenance steps include cleaning the air filter, checking and replacing the spark plug as needed, inspecting fuel lines for damage, and ensuring all nuts and bolts are tight.
To clean the air filter, remove the cover, take out the filter, and wash it in warm soapy water. Allow it to dry completely before reinstalling. Replace if damaged or excessively dirty.
Excessive vibration can be caused by loose screws, a damaged impeller, or debris caught inside the blower. Check and tighten all screws, inspect the impeller for damage, and remove any debris.
The correct spark plug gap for the McCulloch ST 61E Blower is typically 0.6-0.7 mm. Check the user manual for specific details and adjust the gap using a spark plug gap tool if necessary.
For off-season storage, empty the fuel tank and run the engine until it stops to clear the carburetor. Clean the blower thoroughly, lubricate metal parts to prevent rust, and store it in a dry place.
If performance is decreasing, check the air filter and clean or replace it if necessary, ensure the spark plug is clean and properly gapped, and verify that the fuel mixture is correct and fresh.
The McCulloch ST 61E Blower is designed primarily for dry debris. Using it on wet leaves may lead to clogging and reduced performance. Allow leaves to dry before using the blower for optimal results.
