Using the Makita EA4300FRDB chain saw is quite straightforward. First, make sure you've filled the fuel tank with the correct 50:1 fuel mixture and the oil tank with proper lubricating oil. To start the saw, prime the engine using the primer pump, especially in cold weather. Then, use the spring - assisted starter. You'll find it much easier to pull compared to regular starters. Once the saw is running, use the single choke/run/touch stop switch to control its operation. When you're done, just touch the stop lever to turn it off. As for safety, always wear appropriate protective gear like gloves, goggles, and ear protection. The two - point inertia/mechanical chain brake is there to protect you in case of kickback, so be aware of its function. For maintenance, take advantage of the 'tool - less' filter access. Regularly clean the air filter by opening the two - piece cover with a simple turn of the knob. Keep the chain compartment clean to ensure efficient operation. Also, check the chain tension regularly and adjust it if needed. Make sure to lubricate the chain and bar using the oil in the tank. The reversible sprocket nose bar with an oil - retaining feature helps with this. Store the saw in a dry place when not in use, and follow all local regulations regarding its use and storage.
