For cutting large branches (up to 20 cm), Lisam offers a wide range of pneumatic saws produced in conformity with EC standards. The Sky model is the first pneumatic saw, approved for use on an arm, for working without the use of ladders or self-propelled trucks for heights up to 4 metres. Lightweight and easy to handle, the chain is automatically lubricated with a patented system that uses the motor exhaust of the saw, resulting in quick and easy maintenance. The 2SP and SKY models are available with 10 and 8-inch chain bars and with standard shape or tapered bars.
