Chain saw 40 cm 2x18V LI-ION BLDC DUC406ZB

Power and Precision in One Device

A cordless chainsaw with a 40 cm guide bar is a tool designed for efficient wood cutting in both professional and amateur conditions. The device utilizes a 2 x 18 V (36 V) power supply system, translating into high performance while maintaining a compact design. A key structural element is the brushless motor (BLDC), which not only ensures a longer device lifespan but also allows for a chain speed reaching 20 m/s. Such speed is crucial when working with harder wood species, where fast and clean cutting of the material is required without excessive operator effort.

A guide bar length of 40 cm (16 inches) makes this tool versatile – it is suitable for both pruning branches and preparing firewood with a diameter of up to approximately 35-38 cm. A chain with a 3/8" pitch and a 1.3 mm groove width guarantees stable operation and cutting precision. It is worth noting the lubrication system – a 0.2 l oil tank allows for continuous operation without the need for frequent grease replenishment, which is crucial during longer work cycles.

Ergonomics and Safety During Installation and Operation

User safety is ensured by the use of ergonomically shaped, rubberized handles that reduce vibrations transmitted to the operator's hands. An additional advantage is the safety lock function and the chain braking system (mechanical or electronic, depending on the model), which immediately stops the cutting motion in case of kickback. For installers working at heights or in hard-to-reach areas, the manufacturer has provided a special mounting hook. This allows the chainsaw to be safely hung on a strap or rope, significantly facilitating work in a vertical position and reducing the risk of the tool falling.

The device weight (according to EPTA standard) falls within the range of 4.6 – 5.1 kg, which is the result of mass optimization while maintaining housing durability. Such a power-to-weight ratio means the chainsaw does not excessively strain the wrists during multi-hour work. The battery replacement system is simple and intuitive – the device is compatible with popular Li-ion batteries with capacities ranging from 3.0 Ah to 6.0 Ah. This allows the user to adjust the working time to their needs, choosing smaller cells for a lighter kit or larger ones for longer autonomy without breaks for charging.

What is Included in the Set?

It is worth remembering that the DUC406ZB model is a "body only" version, meaning the tool is delivered without batteries and a charger. Such a solution allows for flexible management of the machine park – you can purchase only the cells necessary to start work or use existing batteries compatible with the Makita LXT 18V system. The manufacturer's standard equipment includes all necessary elements for immediate startup:

• Guide bar 40 cm long
• Cutting chain matching the guide bar
• Cutting unit cover protecting during transport
• Toothed spike (factory mounted)
• Socket wrench (size 13-16 mm) facilitating chain tension adjustment

Key technical data affecting daily operation include the supply voltage 2 x 18 V Li-ion Battery (36 V), rotational speed reaching 20 m/s, and cutting length 40 cm. The system uses a 3/8" pitch with a 1.3 mm groove width, and the oil tank capacity is approximately 0.2 l. The total weight is around 4.6 - 5.1 kg (according to EPTA standard) and it is driven by a brushless (BLDC) motor. Thanks to the use of modern BLDC technology and a solid guide bar and accessory construction, this chainsaw offers the reliability needed both in a carpentry workshop and during forestry or gardening work. Chain tension adjustment using the provided wrench allows for quick adaptation of the equipment to working conditions without the need for additional tools or disassembly of covers. This solution saves time and increases the comfort of work every day.
