Using your GearWrench 35720-06 ratchet wrench set is a breeze. First, pick the right size wrench for your fastener. You can easily tell the size as it's stamped on both ends of the beam. Place the ratcheting box end over the fastener. Since it only needs a 5° turn to move the fastener, you can work in tight spaces with ease. Just keep turning the wrench to loosen or tighten the fastener. When using it, make sure to apply even pressure to avoid damaging the fastener. Also, don't use it on fasteners that are too big for the wrench as it might cause the wrench to break. To keep your wrenches in top shape, after each use, wipe them clean with a dry cloth. You can also apply a light coat of oil to prevent rust. Store them in a dry place, preferably in a toolbox to protect them from damage.
