Installation Notes

This tool is used by licensed HVAC technicians, plumbers, pool service professionals, and mechanical trades when servicing equipment with metric hex fasteners. Always de-energize and lock out electrical equipment and shut off fluid systems before loosening or tightening fasteners. Use the short arm for initial engagement in tight spaces and switch to the long arm for final torque. Do not use cheater bars or extensions on the tool handle, as this can damage fasteners or the tool itself.
