Stihl MSA 140 C-B Review

Design and construction

The Stihl MSA 140 C-B chainsaw is a disappointment for those who value both design and construction. This chainsaw comes with an underwhelming design that lacks the aesthetic appeal of other models in its category. The housing of the chainsaw is made of plastic, which gives it a cheap feel despite the high price tag.

Aside from its unimpressive design, there are also concerns about the durability of this product. The quality of materials used to construct it leaves much to be desired, as many users have reported experiencing hardware malfunctions after only a few uses. Furthermore, the chain tension adjustment mechanism is poorly designed, making it difficult to make adjustments without using tools.
