Installation Notes

Installation is performed by electricians, plumbers, HVAC technicians, and other trade professionals using power drills or drill presses. Secure the workpiece before cutting and use appropriate cutting fluid when sawing through metals or stainless steel to extend blade life. Wear eye protection and follow standard tool-safety practices per OSHA guidelines. Allow the saw to cool between cuts when working through hard materials to prevent premature tooth wear.
