3. Setup and Assembly
Follow these steps to assemble your Makita UC3551A Electric Chain Saw. Ensure the tool is unplugged from the power source before beginning assembly.
- Unboxing: Carefully remove all components from the packaging. Verify that all parts listed in the packing list are present.
- Remove Sprocket Cover:

Press the small button on the sprocket cover and turn it counter-clockwise until it releases. Lift the cover off to expose the drive sprocket and guide bar mounting studs. - Install Guide Bar and Chain:

Wearing protective gloves, carefully place the chain around the guide bar, ensuring the cutting edges face the correct direction. Position the guide bar onto the mounting studs, ensuring the chain engages with the drive sprocket. Leave some slack in the chain for easier re-installation of the sprocket cover. - Re-install Sprocket Cover: Align the sprocket cover with the mounting studs and press it into place. Turn the cover clockwise while pressing the button until it locks securely.
- Adjust Chain Tension:

Loosen the sprocket cover slightly. While holding the guide bar up, turn the adjusting dial (located on the side of the saw) towards the '+' symbol to increase chain tension. The chain should be snug against the guide bar but still allow for manual movement. Once tension is correct, tighten the sprocket cover fully.
4. Operation
Before operating the chainsaw, ensure you have read and understood all safety instructions and are wearing appropriate PPE.
Starting the Chain Saw:
- Connect the chainsaw to a suitable power outlet using a heavy-duty outdoor-rated extension cord. Note that the chainsaw does not come with a long integrated cord, so an extension cord is essential for most tasks.
- To start the saw, press the release button (usually located on the handle) with your thumb, then pull the trigger switch with your fingers. The saw will begin to operate with a soft start.
- To stop the saw, release the trigger switch.
Cutting Techniques:
- Bucking: For cutting logs or branches that are supported, use the spike bumper (if present) to pivot the saw into the wood. This helps maintain control and reduces kickback.
- Limbing: When removing branches from a fallen tree, work from the base towards the top. Be aware of branches under tension that may spring back when cut.
- Felling: Felling trees requires specialized training and should only be performed by trained professionals. Always plan an escape path and ensure no one is in the falling area.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your Makita chain saw.
- Chain Lubrication: The saw features a large oil reservoir with a view window. Regularly check the bar oil level and refill with appropriate chain oil as needed. Proper lubrication is crucial for chain and bar life.
- Cleaning the Saw Chain: After each use, clean the saw chain to remove sawdust, sap, and debris. A clean chain operates more efficiently and reduces wear.
- Sharpening the Saw Chain: A sharp chain is essential for effective and safe cutting. Sharpen the saw chain regularly or have it professionally sharpened when it becomes dull. Refer to the full manual for detailed sharpening instructions, including correct angles and file sizes.
- General Cleaning: Keep the motor housing and ventilation slots clean and free from debris to prevent overheating.
6. Troubleshooting
If you encounter issues with your Makita UC3551A chain saw, refer to the following general advice. For detailed troubleshooting steps, consult the comprehensive user manual.
- Saw Not Starting: Check if the power cord is securely plugged in and if the outlet is functional. Ensure the release button and trigger are pressed correctly. Verify the chain brake is disengaged.
- Chain Not Moving: Ensure the chain tension is not too tight or too loose. Check for any obstructions in the guide bar or sprocket area.
- Poor Cutting Performance: A dull chain is the most common cause of poor cutting. Sharpen or replace the chain. Ensure the chain is properly lubricated.
- Overheating: Clean any debris from the motor's ventilation slots. Avoid continuous heavy use; allow the saw to cool down periodically.
