Before operating a machine with two-hand control or two-hand trip, function tests should be done to make sure that the safeguard is adjusted and working properly. These tests should be done at every setup, operator, and shift change, as well as every time after maintenance is performed. This two-hand control and two-hand trip function-testing checklist can be used for this. It is laminated and has a grommet in the corner so it can be kept at the machine.
The checklist has the two-hand control function-testing procedures on the front and the two-hand trip function-testing procedures on the back. It also has the safety-distance equations from ANSI B11.19-2010 that are needed to calculate the safety distance for these safeguarding devices.
