How to use: Attach the lanyard to your harness or belt using the quick - release shackle. Make sure the Velcro on the shackle's release tab is properly secured. Then, connect the Kong Tango double - locking snap hook to the appropriate anchor point in the helicopter. Note: Check the lanyard regularly for any signs of wear, especially the retaining split ring and the quick - release shackle. Do not exceed the rated strength of 3400 lbf. (15kN) for the lanyard and 7425 lbf. (33kN) for the snap hook. Maintenance: Keep the lanyard clean and dry. If it gets dirty, gently wash it with mild soap and water, then let it air - dry completely. Store it in a cool, dry place away from direct sunlight and sharp objects.
