MAKITA, UC4051A, 2000 W, 40 cm, Corded electric chainsaw

The MAKITA UC4051A 2,000 W Corded Electric Chainsaw, 400 mm is a corded electric chainsaw designed for cutting logs, branches, and other wooden materials in home gardens and during property maintenance. It draws 2,000 W from an AC mains supply and drives the chain at 14.5 m/s through a 400 mm guide bar. That bar length sets the maximum cutting diameter achievable in a single pass, placing the tool in the mid-range category for domestic and light-duty commercial cutting. The mains power source removes runtime limitations and battery management, but requires a nearby outlet or extension lead throughout use. Rated exclusively for wood, the saw covers tasks from pruning branches to sectioning small-diameter logs.

Weighing 5,400 g with an overall length of 505 mm, the chainsaw sits in the mid-weight class for electric models of this bar length. The soft-grip ergonomic handle reduces vibration transfer to the operator's hands during prolonged cutting sessions. A soft-start function ramps motor speed up gradually rather than surging to full power, which improves control when starting a cut. Safety features include a chain brake and quick-stop function that bring the chain to a rapid halt when triggered. Automatic chain lubrication feeds oil from a 0.2 L reservoir, while an integrated oil-level indicator allows the operator to check the remaining lubricant without opening the housing. Both chain tensioning and chain replacement are tool-free, so adjustments and routine maintenance can be carried out on site without additional equipment.

• Chain pitch 3/8 in. with 1.27 mm gauge – defines the replacement chain profile for sourcing compatible spares
• 0.3 m power cable – short mains lead; an extension cable is required for most outdoor cutting
• Vibration level 6.7 m/s² during wood cutting – quantifies hand-arm vibration for comparison against other models
• Sound power level 101.9 dB – total acoustic output, relevant for noise planning in residential settings
• Sound pressure level 92 dB – measured operator noise exposure; hearing protection recommended
• Saw chain included – ships with a cutting chain fitted and ready for immediate use
• Overload protection – motor shuts down under sustained excess load to prevent damage
