ABSTRACT:
The present invention is an extended reach tree maintenance apparatus. The invention is comprised of a lightweight electric chain saw, at least two hollow and stackable extensions poles, a bracket, several fasteners, and a wireless ON/OFF switch. The bracket is attached to a handgrip at one end of the lightweight chain saw and has a coupler fixed along its length that facilitates its secured yet removable attachment with one extension pole. At least three fasteners pass through the bracket and contact the chain saw securing the bracket to the chain saw. One fastener depresses the trigger switch of the chain saw in the ON position. The wireless receiver switch is electrically connected to the chain saw and remotely operable via a wireless transmitter. In other embodiments, the invention further comprises a switch electrically connected between the chain saw and the wireless ON/OFF switch and fastened to an extension pole. The switch communicates electrical power to the chain saw when extension poles are within a defined angular range of operation and interrupts power when angular orientation is otherwise.
