Question 1 of 27070

How can the chance of contaminating hydraulic fluid be decreased when working on hydraulic systems?

🔍 Key Concepts

• Hydraulic system cleanliness and how contamination enters the system • Proper procedures before disconnecting or opening any hydraulic line or fitting • Which actions actually prevent new dirt from getting inside, versus only managing existing leaks or damage

💭 Think About

• Which choice directly addresses keeping dirt and foreign material from entering the hydraulic system at the moment you open it? • Which options might deal with leaks or damage but do nothing to reduce the chance of new contamination getting inside the fluid? • Is any option suggesting adding a substance or temporary repair that could itself become a source of contamination?

✅ Before You Answer

• Identify which actions are preventive cleaning steps before opening the system. • Eliminate any answers that involve introducing foreign materials (like sealants or coatings) into areas exposed to hydraulic fluid. • Ask: Which single step would a careful mechanic always do first to keep fittings and connections free from dirt before disassembly?
