The Einhell cordless GE-LC 18/25 Li-Solo combines the outstanding quality of an Einhell product with the cutting performance of a high-quality OREGON guide bar and chain. Kickback protection and an instant-reaction mechanical chain brake protect you while you are working with the chainsaw. A catch bolt holds on to the chain if it jumps off the rail. The rugged metal stop claw keeps the saw stable for your added safety. The ergonomic handle gives you a firm grip on the cordless chainsaw. No tools are needed to adjust the chain tension or replace the chain. The chain is lubricated automatically. The large opening in the oil reservoir eliminates the need for a funnel. This product comes without a battery or charger.
