Frequently Asked Questions - BC4320i Maruyama
How do I start the Maruyama BC4320i lawn mower?
Ensure the fuel tank has fresh petrol, engage the blade brake lever, set the choke to cold start if the engine is cold, then pull the starter cord firmly. Once the engine starts, gradually move the choke to the run position. Always follow the instructions in the manual for safe starting.
What type of oil should I use for the BC4320i?
Use a high-quality 4-stroke engine oil with SAE 30 viscosity for general use, or 10W-30 for varying temperatures. Check the oil level with the dipstick before each mowing session and change the oil after the first 5 hours, then every 25 hours or each season.
How often should I sharpen the mower blade?
Sharpen the blade at least once per season or after every 10-15 hours of use if you notice a torn cut. Remove the blade, clamp it securely, and use a file to maintain the original cutting edge. Balance the blade after sharpening to prevent vibrations.
What should I do if the mower vibrates excessively?
First, turn off the engine and disconnect the spark plug wire. Inspect the blade for damage or imbalance, check the blade mounting bolt, and examine the drive belt. Clean any grass debris from the deck. If vibration persists, consult an authorized service center.
Can I mulch the grass with this mower?
The BC4320i is primarily designed for side discharge or bagging. A mulching kit may be available as an accessory. If you use a mulching plug, always ensure the blade is sharp and mow at a slower speed to achieve fine clippings.
How do I store the mower for winter?
Drain the fuel tank or add a fuel stabilizer, run the engine for a few minutes to circulate stabilized fuel, change the oil, and clean the mower thoroughly. Store in a dry place. Remove the battery if the model has an electric start. Disconnect the spark plug to prevent accidental starting.
What safety precautions should I follow while mowing?
Always wear sturdy shoes and long pants, never mow in sandals or shorts. Clear the lawn of stones, sticks, and debris before mowing. Keep bystanders and pets at least 15 meters away. Never operate the mower in wet grass, and always push uphill when possible.
Why does the engine stop or stall during mowing?
Common causes include a dirty air filter, clogged fuel line, or a damp spark plug. Check the fuel level, clean or replace the air filter, and inspect the spark plug. Also ensure the grass bag is not overfilled and that the discharge chute is clear.
How do I adjust the cutting height?
Locate the cutting height adjustment levers, one at each wheel. Pull the lever outward, move it to the desired position (from 20 to 75 mm), and release it. Make sure all wheels are set to the same height for an even cut.
Where can I find spare parts for the BC4320i?
Spare parts are available at any authorized Maruyama dealer. You can also order parts online through the official Maruyama website or by contacting customer service with your model number and serial number.
