Detailed Description (from Product Description)
The SEYVUM chainsaw is built around an efficient brushless motor that reduces friction and maintenance while increasing run time — a hallmark benefit of a true brushless chainsaw. With a 12 inch bar, this compact model is optimized for a backyard user who needs a brushless 12 inch cordless chainsaw for pruning branches and small logs. The inclusion of two 4.0Ah batteries creates a practical dual-battery strategy: swap and continue working or share batteries across other 20V tools.
The 20V chainsaw features tool-free chain tensioning and an electric chainsaw with tool free chain tension and auto oiling system to simplify maintenance. Before first use, the manufacturer emphasizes adding lubricating oil and running the unit idle for about 10 seconds to confirm oil flow — a necessary step for the chainsaw with auto oiler to protect the bar and chain.
Safety is a priority: the saw requires two deliberate controls to engage, reduces kickback with head design, and stops the chain instantly in a kickback event. This makes the unit a compelling cordless chainsaw for homeowners seeking a balance of power and safety.
