Dynamometer Important Safety Tips
Securely fasten test vehicle using all available restraining ratchet straps. The more straps the better.
Secure both front to back and side to side. Never move the steering wheel for front wheel drive
vehicles while under test.
Always inspect vehicles for fuel or oil leaks before testing as dyno electrical system can ignite fuel
Always perform low speed test run to confirm vehicle is adequately secured and operational before
doing extensive testing.
Keep people away from the dyno test area and NEVER have people stand behind the rear of the
vehicle. Debris may be stuck in the tires tread and may become projectiles during testing.
When operating around rotating parts do not wear loose fitting clothing as they may get caught up in
rotating pulleys or mechanical components
Keep dyno area clean from all loose objects
Keep all hands, feet, and other objects away from moving rolls during tests
Always wear approved safety equipment such as eye protection and steel tow boots around dyno
area
The dynamometer rollers and power absorption units can become very hot during testing. Avoid
contact with them as serious burns or injury can occur.
The dynamometer power absorption units require high voltage DC current to operate.
Contact with the high power electrical wires and boxes may be fatal. Disconnect all power to the
electrical system before inspecting or servicing.
During extended testing vehicle cooling system and engine may become very hot.
Extreme caution is necessary when working near these components.
Always inspect vehicle tires for wear or damage before testing and only operate with tires that are in
good condition and at the proper tire pressure. FOR ALL TIRES TIRE PRESSURE SHOULD BE BETWEEN
1.8 to 2.5 bar (25-35 PSI)
Never let untrained personal operate the vehicle during dyno testing
Exhaust gasses are poisonous and may be fatal.
