Using this Klein Tools Lineman Backpack is simple. First, open the wide opening to place your helmets, belts, and other large equipment inside. Use the large front pocket for gaffs, rubber gloves, or other smaller items. Adjust the padded shoulder straps and the chest strap to fit your body comfortably before putting it on. When you're at the jobsite, you can easily access your gear. Remember, since the bottom has drain holes, avoid placing it on very dirty or wet surfaces to prevent dirt from getting inside. To maintain it, clean it regularly with a damp cloth. Check the double - stitched seams occasionally for any signs of wear and tear. If the backpack gets wet, let it dry in a well - ventilated area before storing it.
