Bar and Chain Installation
Proper installation of the guide bar and chain is crucial for safe and effective operation. Refer to the detailed instructions in your full manual for specific steps.
Chain Tensioning
Correct chain tension is vital. A chain that is too loose can derail, and a chain that is too tight can cause excessive wear and damage. The 445e II features a simple, side-mounted chain tensioning system.
