Using the GearWrench 9901D is a breeze. First, pick the right size wrench for your fastener. You can easily identify the size as it's stamped on both ends of the beam. To use the ratcheting feature, just place the box end on the fastener and start turning. The 72 - tooth ratcheting design only needs a 5 - degree turn to move the fastener, which makes your work much faster. The flexible head can be adjusted to reach those hard - to - get - at spots. You can set the desired head tension using the adjustable set screw. As for maintenance, since it has a full - polish chrome finish, you can simply wipe it clean after use to keep it looking good and prevent corrosion. Also, store the wrenches in the included rack to keep them organized. Remember, this set has a limited lifetime warranty, but avoid using it on fasteners that are too large or too hard for the wrenches to prevent damage.
