Chainsaw Kärcher PSW 18-20 Battery

The Kärcher PSW 18-20 Battery chainsaw pole saw with extension insert is designed for cutting and maintaining tall trees from the ground. Its 30° angled blade allows comfortable cutting of branches at heights up to 4 metres while the operator remains on the ground. The kit includes the device, blade, chain, blade guard, shoulder strap, hex key for chain tensioning and an oil bottle.

Advantages

The tool is lightweight (4.9 kg) and compact, with a 20 cm bar that enables precise cuts. Operation is powered by an 18 V battery and the chain runs at 5.5 m/s. Simple chain tensioning, automatic chain lubrication and a low vibration emission (1.3 m/s²) increase user comfort and reduce fatigue. An included shoulder strap improves handling during prolonged use.

Suitable for

• Pruning and trimming branches on tall trees up to 4 m high
• Garden maintenance where safe ground-level cutting is required

Recommendations

Use appropriate personal protective equipment (gloves, eye and ear protection, helmet if working under falling branches). Do not exceed the recommended cutting height and follow battery manufacturer guidelines for charging and storage. Regularly check chain sharpness and oil level to maintain cutting performance.
