MSA 140 C-BQ

MSA 140 C-BQ
An affordable battery-powered chainsaw delivering excellent cutting performance for tree maintenance in large suburban yards.

Product Description

The MSA 140 C-BQ is the most powerful chainsaw in the STIHL Lightning Battery System® AK Series when paired with the AK 30 battery. It delivers excellent cutting performance for up to 45 minutes on a single charge and is ideal for limb removal and storm cleanup. This chainsaw is a good option for suburban homeowners who perform yard work in noise-sensitive areas. It is compact and lightweight at 8.6 lbs. with the bar and chain and AK 30 battery, and 5.7 lbs. without battery, making this chainsaw easy to use and maneuver. The MSA 140 C-BQ also features the exclusive ¼” STIHL PICCO™ saw chain which assures clean, smooth cuts, and has a high-torque brushless motor delivering ideal speed and durability for a virtually maintenance-free service life.

The actual listed guide bar length can vary from the effective cutting length based on which powerhead it is installed on. Run time may vary based on battery type, charge level and capacity, model, operating style and conditions. Batteries and chargers can be purchased separately or as a combined set with tool.
