Makita DUC405Z 36V LXT Cordless Chainsaw 400mm 20 m/s Brushless Motor

The dual 18V LXT battery system uses two Makita 18V batteries to deliver higher power output and longer runtime than a single battery. This setup enables the saw to maintain strong cutting performance during longer jobs, while the brushless motor helps maximize efficiency and battery longevity.

Use the tool-free chain tensioning mechanism: locate the tensioning knob on the side of the bar cover, rotate it to loosen or tighten the chain, and check that the chain has a small amount of play in the middle of the bar. After adjustment, ensure the bar nose remains aligned and reposition the bar cover securely.

Key safety features include a chain brake that halts the chain instantly on kickback, a chain catcher, automatic chain lubrication to reduce the need for manual maintenance, low-vibration technology for steadier handling, and an ergonomic soft-grip handle to improve control and reduce user fatigue.

Regularly check and adjust chain tension, keep the bar and chain clean from debris, ensure the automatic lubrication system is functioning, inspect the chain for wear, and clean the air vents on the motor housing. Periodically inspect the batteries and connectors for corrosion or damage and store the tool in a dry place when not in use.

First, remove the batteries and ensure the saw is powered down. Remove the side plate, take off the old chain and bar, clean the guides, install the new bar and chain in the correct orientation, reattach the side plate, and use the tool-free tensioning mechanism to set the chain tension. Finally, verify that the chain moves freely by hand without binding before reinstalling the batteries.

It's well-suited for trimming branches, pruning around properties, preparatory firewood cutting, and other outdoor cutting tasks where power cords are impractical and noise needs to be minimized compared with gas-powered models.

Compared to similar Makita cordless chainsaws on Fepy, the DUC405Z offers a larger 400 mm bar, a dual 18V LXT battery setup for extended runtime, and a brushless motor for efficiency.

Use two fully charged 18V LXT batteries for best performance, keep the chain adequately lubricated, maintain proper chain tension, cut with smooth, steady strokes rather than forcing the saw, and allow the motor to cool during longer sessions. Store batteries in a cool, dry place and avoid exposing the tool to extreme temperatures.

Always wear cut-resistant gloves, eye protection (safety glasses or a face shield), hearing protection, sturdy boots with good grip, and a helmet with a face shield when necessary. Keep bystanders at a safe distance and follow best practices for kickback avoidance.

If you’re not satisfied with the DUC405Z, you can initiate a return according to Fepy’s returns policy within the specified return window, provided the product is in resale condition with all original accessories and packaging. Check the return process for eligibility and steps.

The kit typically requires two 18V LXT batteries and a compatible charger (often sold separately). It’s also wise to have a chain sharpening tool, spare chains, and a bar oil/lubricant suitable for outdoor use. Always verify the included accessories listed on the product page.
