2.0 Safety Guidelines
Safety is the most important consideration when operating any dynamometer system. Operators and
service personnel should read this manual and become familiar with its content before attempting to
operate this machine or to perform service or maintenance to it. Familiarization with this manual will
minimize the possibility of accidents or injuries. Although the procedures covered in this manual have
proven safe in use, Power Test assumes no responsibility for personal injury or damage to equipment
resulting from its applications. All operators must be aware that there are several hazards present to
anyone in the test cell. Some of these hazards are:
• Objects rotating at high speeds
• Pressurized hoses
• Hot solids or liquids
• Electrical shock
• Flammable liquids
• Exhaust emissions
• Noise
Certain precautions must be exercised. They are:
• DO NOT operate without ALL shields, guards, and emergency cutoffs in place and operating.
• DO NOT enter the test cell during an engine test unless necessary.
• DO NOT wear loose fitting clothing in the test cell.
• Warning decals are located near areas of potential danger. Replace damaged or lost decals.
• DO NOT make any connections while power is applied to the system.
• DO NOT open any panels while power is applied to the system.
• DO NOT make any plumbing connections without shutting down all water supplies and pumps.
• DO bleed air pressure from all lines before connecting or disconnecting any air hoses.
• ALWAYS wear eye protection.
• ALWAYS wear eye and hearing protection whenever the engine is operating.
• ALWAYS keep work area clean. If a spill occurs, eliminate the hazard immediately.
• NO smoking or open flame in the test area.
These are general guidelines for working with a dynamometer system. It is often helpful to prepare a
safety checklist that is distributed to all personnel who enter the test cell. Proper safety is achieved through
reinforcement and discipline.
