Using the Aervoe 1187-5 safety cones is a breeze. First, take the cones out of the storage case. Expand them and attach the 8-pound weighted rubber base for stability. Place the cones where you need to mark a hazard or a restricted area. The red LED beacon lights can be installed on top of the cones; just insert the AAA batteries to power them up. When it's time to store them, collapse the cones flat and put them back in the storage case. As for maintenance, keep the cones clean by wiping them with a damp cloth. Check the LED lights and batteries regularly to ensure they're working properly. Also, inspect the cones for any signs of damage, like tears in the nylon or issues with the reflective stripes. If you notice any problems, refer to the one-year manufacturer's warranty.
