Using your Klein 5471FR Flame - Resistant Electrode Bag is a breeze. First, use the tunnel loop to slide the bag over your belt. This allows you to keep your hands free while you work in the field. When putting electrodes or other small tools inside, make sure they fit well and won't fall out easily. As for maintenance, it's important to keep the bag clean. You can gently wipe it down with a damp cloth after use. Avoid exposing the bag to excessive heat or sharp objects that could damage the flame - resistant canvas or the hard - leather bottom. Also, check the tunnel loop regularly to ensure it's in good condition for easy belt attachment. When not in use, store the bag in a cool, dry place. That way, your bag will last a long time and continue to provide the protection you need in the field.
