Using the Klein BAT207T5 battery - operated bolt cutter is easy. First, make sure the DeWALT 20V lithium - ion 2 Ah batteries are fully charged. Insert the batteries into the cutter. When you're ready to cut, place the 3/8 - inch EHS guy wire or Grade 8 bolt in the cutting jaw. Then, activate the cutter. The 7 - ton hydraulic force will do the rest. When working in dark areas, use the two work lights to get a clear view. Remember, only use it for cutting bolts and steel as specified. Don't try to cut materials that exceed its capacity. After use, store the cutter in the provided tool bag. Check the batteries regularly and recharge them when needed. If the cutting performance decreases, consider replacing the blades. Keep the cutter clean and dry to ensure its long - term performance.
