Installation Notes

Hand tools of this type should be used by qualified trade professionals familiar with fastener torque requirements for the specific application. Always confirm the wrench jaw size matches the fastener before applying force to avoid rounding. Inspect the wrench for cracks or deformation before each use and remove it from service if damage is found. Do not use extension bars or pipe extensions on standard combination wrenches unless the tool is rated for that use.
