Q

If the drive belts on an air compressor were squealing during start-up, you should do which of the following?

🔍 Key Concepts

• Drive belt squeal usually points to a mechanical issue like tension, alignment, or excessive load on start-up • What conditions make an air compressor harder to start turning (increased starting load)? • Difference between components that affect starting load (air path / pressure) vs those that act only at high pressure cut-out

💭 Think About

• Ask yourself: which choice relates directly to the mechanical load on the belts at the moment of start-up? • Which option would affect how much resistance the compressor sees as it begins to turn and compress air? • Which components in the list only come into play when the compressor is already running and has built up pressure, rather than at the instant of start-up?

✅ Before You Answer

• Identify which options deal with initial load on the compressor versus control/safety at high pressure • Consider which items would cause the compressor to start against pressure instead of starting unloaded • Eliminate any options that mainly act as electrical safety devices or running condition controls, not start-up load controls
