Connecting
Grasp the coupling behind the sleeve and firmly push it inward on the nozzle.
Make sure the coupling slides into the nozzle groove and makes complete
engagement.
Disconnecting
Grasp the coupling sleeve and firmly pull it away from the nozzle. If air pressure
is flowing to the grip when you disconnect the nozzle, there will be a pressure
discharge.
Manual Foot Switch
The pneumatic foot switch allows you to close or open the grips while keeping
your hands free for aligning the test specimen. This mechanically actuated switch
is independent of the test system. The foot switch system consists of the switch
assembly and three air lines. Two air lines, marked upper and lower grip, are
attached to the switch assembly at the factory. The other end of the hoses have
quick disconnect fittings for connecting to the grips. The third air line has a
female threaded fitting on both ends for connecting to the air supply. Figure 3-8
on page 3-11 illustrates the foot switch.
Crush Hazard - Take care when installing or removing a specimen,
assembly, structure, or load string component.
Installation or removal of a specimen, assembly, structure, or load string
component involves working inside the hazard area between the grips or
fixtures. When working in this area, ensure that other personnel cannot operate
any of the system controls. Keep clear of the jaws of a grip or fixture at all
times. Keep clear of the hazard area between the grips or fixtures during
actuator or crosshead movement. Ensure that all actuator or crosshead
movements necessary for installation or removal are slow and, where possible,
at a low force setting.
