The Senix pole saw features a 26.5cc 4-cycle engine that does not require mixing gas and oil but remains lightweight and powerful for cutting limbs out of reach of a handheld saw. Four-cycle engine has lower emission and is more environmentally friendly than 2-cycle. An extension pole is included to extend the reach up to 15 Ft. The Oregon 8 In. bar and chain with auto oiler delivers clean, precision cuts. The shoulder strap provides additional stability and support during operation. All Senix 4QL gas powered products are backed by our 3-year limited warranty for your peace of mind.
