Frequently Asked Questions - BL4801 Maruyama
What fuel mixture does the Maruyama BL4801 require?
Use a 50:1 ratio of unleaded gasoline (87 octane or higher) to premium 2-stroke engine oil. Do not use pre-mixed fuel or fuel containing more than 10% ethanol.
How do I start the BL4801 leaf blower?
1. Fill the fuel tank with fresh fuel mixture. 2. Set the choke lever to the cold start position. 3. Pump the primer bulb 5-7 times. 4. Pull the starter rope sharply until the engine fires, then open the choke and pull again to start.
Why does my blower run but not blow at full power?
Check the air filter for dirt. Clean or replace it. Also ensure the spark arrestor screen is not clogged. A dirty filter reduces airflow and engine performance.
How often should I replace the spark plug?
Replace the spark plug every 100 operating hours or once a season. Use a NGK BPMR7A or equivalent. Ensure the gap is set to 0.6 mm.
What type of oil should I use for the air filter?
Clean the foam air filter with warm soapy water, dry it, then apply a thin coat of clean 2-stroke oil or air filter oil. Squeeze out excess before reinstalling.
How do I store the BL4801 for the winter?
Drain the fuel tank and run the engine until it stalls to remove fuel from the carburetor. Remove the spark plug and add a teaspoon of oil into the cylinder, pull the starter slowly, then reinstall the spark plug. Store in a dry place.
What safety gear should I wear when using this blower?
Always wear ANSI-approved safety glasses, hearing protection, long pants, sturdy shoes, and avoid loose clothing. Operate only outdoors in well-ventilated areas.
Can I use the blower in wet conditions?
No, do not operate the blower in rain or wet grass. Moisture can damage the engine and create a slip hazard. Use only in dry conditions.
How do I adjust the idle speed?
Locate the idle adjustment screw (usually T or L marking). Turn clockwise to increase idle speed, counterclockwise to decrease. The engine should idle without the tube moving. Refer to the manual for precise settings.
What is the warranty period for the BL4801?
Maruyama offers a 2-year limited warranty for consumer use. Warranty covers defects in materials and workmanship. Proof of purchase required. Does not cover normal wear items like filters and spark plugs.
