Frequently Asked Questions - BL4800 Maruyama
What type of fuel does the BL4800 require?
The BL4800 requires a mixture of unleaded gasoline and 2-cycle engine oil at a 50:1 ratio. Use fresh fuel with a minimum octane rating of 89.
How do I start the blower?
Ensure the fuel tank is filled and the on/off switch is in the 'I' position. Set the choke to the closed position (if cold), press the primer bulb 5-6 times, then pull the starter rope firmly until the engine fires. Open the choke and pull again to start.
What is the recommended fuel mix ratio?

How often should I clean the air filter?
Clean the air filter every 25 hours of operation or more frequently in dusty conditions. Wash with warm soapy water, rinse, and allow to dry completely before re-oiling with air filter oil.
How do I store the blower for winter?
Drain the fuel tank and run the engine until it stalls to prevent fuel varnish. Remove the spark plug and add a teaspoon of oil into the cylinder, then pull the starter slowly to distribute. Store in a clean, dry place.
