3. Engage the Safety Features:
1. Most chainsaws have safety features that you should read before starting. These features include a safety switch or a lock button.
4. Start the Chainsaw:
1. Press the power button or switch to start the chainsaw. Ensure that any required safety switches are engaged, as some models require you to press and hold them simultaneously.
2. Once the chainsaw is on, you should hear it start to run, and the chain should begin to move.
5. Check the Chain Speed:
1. After starting the chainsaw, gently press the throttle to increase the chain speed.
2. Make sure the chain moves smoothly and at the correct speed.
3. If the chain is moving too slowly or not at all, double-check the battery charge and chain tension.

By following these steps, you can start your battery chainsaw easily. Always remember to keep safety as your top priority. Simultaneously, follow the manufacturer's instructions.

3. How to Use a Battery Chainsaw

Basic Safety Tips for Battery Chainsaw

Before starting your cutting operation, it is essential to follow some safety tips.

1. Proper Body Positioning:
1. Hold stable position: Keep your feet shoulder-width apart for stability.
2. Bend Your Knees: Do not bend over. You should bend your knees to lower your body. This helps you keep balance and reduces the strain on your back.
3. Keep Chainsaw Close to Your Body: Keep your cordless chainsaw close to your body. It will reduce fatigue and gives you better control.
2. Control and Balance:
1. Firm Grip: Hold the chainsaw with both hands.  You should put right hand on the rear handle. Similarly, keep your left hand on the front handle (it is for right-handed users).
2. Do Not Overreach: Keep your body balanced. Similarly, do not reach out too far. It can result in losing control and balance.
3. Avoiding Kickback Zones:
1. Understand Kickback: Kickback happens when the tip of the chainsaw’s guide bar touches an object. The saw will jerk back towards you. This can be dangerous.
2. Do not use the Tip: Never use the tip of the guide bar to cut. It is recommended to use the lower part of the bar.
3. Install a Chain Brake: Cordless chainsaws have chain brake feature. This feature stops the chain instantly in case of any kickback.

Battery Chainsaw Cutting Techniques

1. How to Make Straight Cuts:
1. Mark the Cutting Line: Use a marker or chalk to draw a straight line on the wood where you intend to cut.
2. Align the Chainsaw: Position the chainsaw and ensure guide bar is aligned with the cutting line.
3. Start Cutting: Begin the cut by pressing the throttle. Allow the chainsaw to reach full speed before touching the wood.
2. How to Make Curved Cuts:
1. Draw the Curve: Outline the curve you want to cut on the wood.
2. Position the Chainsaw: Start at one end of the curve.
3. Cut Slowly: Move the chainsaw slowly and follow the curve. Similarly, you can adjust the angle of the guide bar.
3. Tips for Cutting Different Types of Wood:
1. Softwood (e.g., Pine, Fir): Softwoods are easier to cut. Use a moderate speed and steady pressure.
2. Hardwood (e.g., Oak, Maple): Hardwoods are denser and require more power. Ensure the chain is sharp and cut slowly.
3. Wet Wood: Wet wood can be slippery and may clog the chainsaw. Cut at a slower speed and clean the saw regularly.
4. Knotted Wood: Knots are harder to cut through. Slow down as you approach the knot to avoid kickback.

Handling the Battery Chainsaw

Proper handling of the chainsaw is crucial, both during cutting and when moving around with it.

1. Proper Grip and Handling:
1. Two-Handed Grip: Always use both hands to hold the chainsaw. Keep your right hand on the rear handle and left hand on the front.
2. Firm Stance: Stand with your feet apart for balance and stability.
2. How to Handle the Chainsaw When Moving Around:
1. Switch Off: Always turn off the chainsaw before moving. Remove the battery if necessary.
2. Grip the Handle: Carry the chainsaw by its front handle, with the guide bar pointing backward.
3. Keep the Chain Brake On: Engage the chain brake to prevent the chain from moving if it gets accidentally turned on.

4. How to Maintenance a Battery Chainsaw

1. Cleaning the Chainsaw After Use:

1. Importance: Wood debris, sap, and dirt buildup can cause several issues. For example, affect chain lubrication, hinder smooth operation, and accelerate wear on the chain and guide bar.
2. Process:
1. Safety First: Disconnect the battery and ensure the chain brake is engaged before cleaning.
2. Remove Debris: Use a plastic scraper or brush to remove wood chips and sawdust from the bar, sprocket, and chain.
3. Compressed Air: Remove any remaining debris with compressed air.
4. Lubricate Metal Parts: Use a thin coat of oil on exposed metal parts to prevent rust.

2. Checking the Chain Tension:

1. Process:
1. Read the user Manual: Refer to your chainsaw's user manual for specific instructions on chain tension adjustment. Most models have a tensioner knob near the bar mount.
2. Pull Test: Keep your engine off and the chain brake engaged. Gently pull the chain away from the bar with your fingers. There should be about 1/8" to 1/4" (3-6mm) of play up and down.
3. Adjusting Tension: Turn the tensioner knob clockwise to tighten or counter-clockwise to loosen the chain.

3. Checking the Chain for Wear and Damage:

1. Inspection Points:
1. Sharpness: Check the cutting teeth for dullness. Worn teeth appear rounder and lack the sharp pointed edges.
2. Depth Gauges: The depth gauges are small metal tabs. You can find them on the top of the drive links. They control the depth of each cut. Ensure the depth gauges are the same height as the cutting teeth.

4. Battery Care and Storage Tips:

1. Charging:
1. Use the Correct Charger: Only use the original charger or one specifically designed for the battery model.
2. Cool Down: Allow the battery to cool down to room temperature before charging.
2. Storage:
1. Cool and Dry Location: Store batteries in a cool, dry place out of direct sunlight. Extreme temperatures can damage battery cells.
2. Long-Term Storage: For extended storage periods (months), some manufacturers recommend storing batteries at cooler temperature (around 4°C or 40°F).
3. Periodic Charging: Even during storage, batteries can lose charge over time. Recharge it to around 50% capacity if it falls significantly.

5. How to Sharpen a Battery Chainsaw Chain?

Important Tools and Materials

1. Chainsaw File: A round file specifically for chainsaws or a chainsaw sharpening tool.
2. Safety Gear: Gloves, safety glasses, and ear protection for protection.

Sharpening a Battery Chainsaw Chain

Prepare the Chainsaw:

1. Turn Off the Chainsaw: Make sure the chainsaw is completely off and the battery is removed.
2. Secure the Chainsaw: Place the chainsaw on a stable workbench.  Use a clamp to secure it.

Position the File Guide:

1. Select the Right File Guide: Make sure you have the correct file guide. It should match the size of your chain.
2. Align the Guide: Position the file guide at the proper angle. Most chains require a 30-degree angle. However, you should check your chainsaw’s manual also.

Sharpen Each Tooth:

1. Start with the Shortest Tooth: Begin by locating the shortest cutter tooth, which will serve as your starting point.
2. File with Even Strokes: Place the file in the notch on the front of the cutter tooth.  Push it through the notch using even strokes. Maintain the same angle throughout.
3. Count the Strokes: Apply the same number of strokes (usually 3-5) to each tooth g.
4. Alternate Sides: After sharpening one side, move to the other side of the chain and repeat the process.

Check the Chain:

1. Inspect Each Tooth: Make sure each cutter tooth is sharp and even.
2. Adjust Depth Gauges: Use a depth gauge tool. So you can ensure the depth gauges are slightly lower than the cutter teeth.

Reinstall the Chain:

1. Reattach the Chain: Place the chain back onto the chainsaw. Ensure it fits correctly on the guide bar.
2. Tighten the Chain: Adjust the tension so the chain is snug.
3. Test the Chainsaw: Reinsert the battery and give the chainsaw a quick test run.

6. Conclusion

A cordless chainsaw is a pretty simple tool and convenient to use. However, you should have proper knowledge to start, use and maintain it for optimum results. Avoiding these steps can cause injury and impact tool performance also. By following this guide you can polish your skills and expedite wood cutting operations.
