5 Pro Tips for Firewood Cutters Using the Stihl MS 500i

Now, let’s dive into some pro tips to maximize the MS 500i’s potential for firewood cutting.

1. Choosing the Right Bar and Chain

The MS 500i can accommodate bar lengths from 16″ to 36″. For firewood cutting, I recommend a 20″ or 25″ bar. This length provides a good balance between maneuverability and cutting capacity.

• 20″ Bar: Ideal for smaller to medium-sized logs. It’s easier to handle and allows for faster cutting speeds.
• 25″ Bar: Suitable for larger logs. It provides more reach and allows you to tackle thicker pieces of wood without excessive bending.

As for the chain, the Stihl Oilomatic Rapid Micro (RM) and Rapid Super (RS) are excellent choices. The RM chain is a low-vibration chain that provides smooth cutting and reduced kickback. The RS chain is a high-performance chain that offers faster cutting speeds.

Pro Tip: Regularly sharpen your chain. A sharp chain cuts faster, reduces strain on the engine, and improves safety. I personally use a chainsaw chain sharpener with a guide to maintain the correct angle and depth.

2. Mastering Cutting Techniques for Efficiency

Efficient cutting techniques are crucial for maximizing productivity and minimizing fatigue. Here are a few techniques I’ve found particularly useful:

• Limbing: Start by limbing the tree, removing all the branches. Work from the base of the tree towards the top, keeping the chainsaw close to your body. Use the bumper spike to pivot the saw and make clean cuts.
• Bucking: Bucking is the process of cutting the tree into manageable lengths. Before bucking, assess the log for tension and compression. Make relief cuts to prevent the bar from getting pinched.
• Boring Cut: For large-diameter logs, consider using a boring cut. This involves plunging the tip of the bar into the log and then sawing outwards. This technique is particularly useful for preventing pinching and controlling the direction of the cut.

Pro Tip: Always maintain a stable stance and keep both hands firmly on the chainsaw. Avoid overreaching or cutting above shoulder height.

3. Optimizing Fuel and Oil Mix

The MS 500i requires a specific fuel and oil mixture. Stihl recommends a 50:1 ratio, which means 50 parts gasoline to 1 part 2-stroke oil. Use high-quality gasoline with an octane rating of 89 or higher. I prefer using Stihl Ultra HP 2-stroke oil, as it’s specifically designed for Stihl engines and provides excellent lubrication and protection.

Pro Tip: Mix your fuel and oil in a separate container and shake it thoroughly before pouring it into the fuel tank. Avoid using old or contaminated fuel, as it can damage the engine.

4. Maintaining Your Chainsaw for Longevity

Regular maintenance is essential for keeping your MS 500i in top condition. Here are a few key maintenance tasks:

• Cleaning: Clean the chainsaw after each use. Remove sawdust and debris from the bar, chain, and engine. Use compressed air or a brush to clean hard-to-reach areas.
