What should be done before starting a chainsaw to ensure safety?

Before starting a chainsaw, ensuring that safety features function correctly is a crucial step to prevent accidents and injuries. Safety features on a chainsaw may include the chain brake, throttle latch, and handguards. Verifying that these components are in good working order will help prevent accidental starts and provide protection if the chainsaw kicks back or if the operator loses control during use.

In the case of the other options, inspecting the area for debris might seem relevant, but it primarily addresses environmental hazards rather than the tool's safety. Ignoring external nuts and bolts could lead to mechanical failures due to loose components. Starting the chainsaw instantly without any inspection disregards fundamental safety practices and increases the risk of injury. Overall, checking that safety features are functioning correctly is essential for both the operator's safety and the safe operation of the equipment.
