Compressed air can blow dust into the eyes. Wear eye protection. Do
not exceed 30 psi (207 kPa) air pressure.
Secure motor to test bench.
Electrical high voltages can cause serious injury or death. Some tests
require power to be connected. Always take proper measures to ensure
Connect motor wiring to test bench leads.
