Product Information
Full details
The Makita DUC405Z 40cm Brushless Chainsaw is designed for users needing a powerful, cordless cutting solution for landscaping, arborist work, or property maintenance. Its key benefit is the efficient brushless motor powered by two 18V LXT batteries, offering high chain speed and performance comparable to gas-powered models without the emissions or noise. A potential caveat is that it is supplied as a bare unit, requiring users to have or purchase batteries and a charger separately, although this specific package includes two 6.0Ah batteries and a dual charger.

FAQs
What is the runtime on a single charge?
Runtime varies significantly based on battery capacity (e.g., 6.0Ah), the type of wood being cut, and cutting technique. With two 6.0Ah batteries, users can expect to perform a substantial amount of cutting for typical property maintenance tasks before needing to recharge.
How do I tension the saw chain?
The DUC405Z features tool-less chain tensioning integrated into the sprocket cover. Loosen the guide bar nuts slightly, adjust the tension using the knob on the chain cover until the chain is snug but can still be pulled freely by hand, then retighten the guide bar nuts.
Is this chainsaw suitable for felling large trees?
The 40cm bar length is suitable for felling small to medium-sized trees. For larger diameter trees, a saw with a longer bar and higher power output would be more appropriate.
What type of oil should I use for the chain oiler?
Use a dedicated bar and chain oil designed for chainsaws. Do not use motor oil or other lubricants, as they may not provide adequate lubrication or could clog the oiling system.
Does this model come with batteries and a charger?
This specific product listing (DUC405Z) includes 2 x 6.0Ah batteries and a dual charger. However, Makita also offers 'bare tool' versions that do not include batteries or chargers.
How does the auto power-off function work?
The main power switch is designed to automatically shut down if the trigger is not pulled for a certain period after the main power switch is turned on. This is a safety feature to prevent unintentional startups and conserve battery power.
Troubleshooting
Chainsaw will not start
Ensure both batteries are fully charged and correctly inserted. Check that the safety lock is disengaged and the trigger is being squeezed. Verify the auto power off function hasn't activated; if so, briefly release and re-engage the trigger.
Chain is not cutting effectively or is slow
Check if the chain is dull and requires sharpening. Ensure the chain tension is correct – not too loose or too tight. Verify the chain oil reservoir is filled and the automatic oiler is functioning.
Chain stops during use
This could be due to overheating, low battery power, or an obstruction. Release the trigger and allow the tool to cool if it feels excessively hot. Check battery charge levels. Inspect the chain and bar for any binding or debris.
Chain oil is not being delivered
Check the oil level in the reservoir. Ensure the oil hole in the guide bar is not clogged. Clean any debris from the oiler drive mechanism on the powerhead.

Setup, Compatibility & Care
Setup:
- Ensure two fully charged Makita 18V LXT batteries are inserted correctly into the battery compartments.
- Attach the guide bar and chain, ensuring the chain is tensioned correctly. Use the integrated tool or a separate tensioning tool as needed.
- Fill the chain oil reservoir with appropriate bar and chain oil.
- Engage the safety lock and squeeze the variable speed trigger to test operation.
Compatibility:
This chainsaw is compatible with all Makita 18V LXT Lithium-Ion batteries. For optimal performance, Makita recommends using batteries with higher amp-hour (Ah) ratings (e.g., 5.0Ah or 6.0Ah) for extended runtimes.
Care:
- Cleaning: After each use, clean the guide bar, chain, and sprocket cover of sawdust and debris. Wipe down the motor housing with a damp cloth.
- Chain Maintenance: Keep the saw chain sharp for efficient cutting and reduced strain on the motor. Check and adjust chain tension regularly.
- Oiling: Monitor the chain oil level and refill as needed. Ensure the oiling system is not blocked.
- Storage: Store the chainsaw in a dry place, away from extreme temperatures. Use the provided guide bar cover during storage and transport.
- Battery Care: Store batteries in a cool, dry place and avoid exposing them to extreme heat or cold. Follow Makita's guidelines for battery charging and maintenance.
