What should you ensure regarding the number of drivers when ordering a saw chain?

In the context of ordering a saw chain, ensuring that the number of drivers matches the original chain is crucial for proper compatibility and functionality. The drivers of a chain are the parts that fit into the guide bar grooves and engage with the sprocket, enabling the chain to move effectively. If the new chain has a different number of drivers than the original, it could result in improper fitting on the guide bar, leading to issues such as chain derailment or inadequate power transfer from the saw. Therefore, matching the number of drivers ensures optimal performance, safety, and efficiency when using the chainsaw.
