turbocharger inlet or any screen that prevents ingestion of debris and protects fingers. If air flow is
restricted, testing results may be skewed. If another shield is used, stall check results may be affected.
Also, excessive black smoke will occur. See Figure 4-4.
Noise from powerplant could damage hearing. Use double ear
11. Install elbow and clamp on engine turbocharger exhaust outlet. Adjust elbow so that exhaust is directed
away from personnel.
