Installation Notes

This tool is used by licensed mechanical, HVAC, and plumbing technicians during equipment installation and service. Always power down or isolate the equipment being serviced before using hand tools on fasteners. Ensure the hex key is fully seated in the fastener socket before applying torque to avoid rounding. Inspect the tool for cracks or deformation before each use and replace if damage is found.
