Installation Notes

Pin punches are used by licensed mechanics, machinists, and trade technicians. Always de-energize and lock out equipment before driving or removing pins from assemblies. Use an appropriate ball-peen or machinist hammer matched to the task. Eye protection is required when striking punches, as metal fragments can be ejected during use.
