The JACK chainsaw is the most practical and efficient pruning tool available in the market for professional operation. The innovating intermittent chain lubrication system allows a long lasting oil reserve. JACK is comprised of a pneumatic vane engine set with an “AIR PLUS” air inlet system, which makes it possible to reduce air consumption and increase power for cuts on branches up to 300 mm. New versions with a “Carving” pointed bar allow more precise cuts with easier handling of the chainsaw. All JACK chainsaws are fitted with high-mechanical resistance polyamide material casing.
