Use the RYOBI 18V ONE+ 12" (304mm) HP™ Brushless Chainsaw to prune branches and prepare firewood. It's a great tool for garden maintenance and collecting logs (especially on camping trips)*. Impressive power, easy maintenance and built-in safety features make this an efficient, hassle-free tool to operate.

The Kit also features an 18V ONE+ 4Ah Battery and 18V ONE+ 1.5A Charger.

Brushless power
The advanced HP brushless motor delivers a powerful performance and enhanced cutting efficiency. It generates high blade speeds to cut through material fast. The bar length allows for cutting branches/logs measuring up to 200mm in diameter.

Low maintenance
Automatic chain oiling** keeps the bar and chain lubricated while you work.

A tool-less chain tensioning system enables quick chain tension adjustments and chain replacements. It’s all controlled by a chain tensioner knob on the side.

Enhanced safety and control
Bumper spikes at the base of the guide bar grip onto logs/branches to anchor the Chainsaw, allowing smooth, controlled pivoting through each cut.

The integrated front guard and fast-acting chain brake provide added user protection by reducing kickback.

A balanced twin-handle layout delivers a comfortable, secure grip, improving control and reducing fatigue over long, repetitive jobs.

ONE+ powered
The Battery is compatible with hundreds of products from the RYOBI ONE+ range. It powers the Chainsaw to deliver up to 35 cuts of 100mm diameter logs*** on a single charge.

*Timber collection rules may vary by region. Confirm requirements with your local council or relevant land authority before cutting or removing wood from bushland areas and camping grounds.

**This model requires chain and bar oil (sold separately) for operation.

***Tested in dry conditions with Australian Hardwood species (Ironbark, Sugar Gum) using an 18V 4Ah Battery.
