Installation Notes

Chain installation should be performed by a qualified operator following the chainsaw manufacturer's guidelines. Remove the battery pack and confirm the unit is fully powered down before handling the guide bar or chain. Use appropriate bar wrenches and tensioning tools to achieve correct chain tension — neither overly tight nor slack. Inspect the drive sprocket and guide bar for wear before installing a new chain, and ensure the bar oil reservoir is filled before operation.
