The Greenworks G40PSH 2-in-1 cordless pole chainsaw and hedge trimmer features a 51 cm hedge trimmer and a 20 cm chainsaw, along with an extendable telescopic pole. The trimmer head can be adjusted to 7 different positions and tilted up to 125 degrees. The G40PSH can operate for up to 30 minutes and includes a switch lock feature, a safety function that prevents accidental starting of the device. With the telescopic handle, hard-to-reach areas can be accessed without a ladder. Please note that the G40PSH requires a 40 V - 2 Ah/4 Ah battery and a 40 V universal charger, which are not included. All battery-operated tools from Greenworks that operate at the same voltage can be powered by the same 40 V battery, meaning you only need one battery. However, if you have 2 batteries, you can extend your working time by charging one while the other is in use. Highly recommended!.
