Safety system description
The Haeger Hardware Insertion Machine is equipped with a unique, reliable and patented Safety System .
Conductive Mode
When the Safety System detects a non- conductive material between the Upper and Lower Tools, the
Upper Tool
’ s downward motion reverses immediately and returns to its Up position.
Non-conductive mode
The Upper Tool ’ s downward motion stops when any material is placed between the Upper and Lower
Tools. If the Down Footswitch is depressed a second time after the Upper Tool has stopped, the
machine continues the hardware insertion cycle. It applies the machine
’ s set down force to the
material. The Upper Tool then returns to its Up position.
How the safety system works
In both Conductive and Non-Conductive modes, the Safety System relies on the Safety Switch inside the
Cylinder Adapter. The Upper Tool Holder Retainer Screw secures the Upper Tool Holder to the Cylinder
Rod . There is a black serrated knob on this Retainer Screw. It enables the Upper Tool Holder to move up
on the Cylinder Adapter .25 in./6.4 mm. To move up, the Upper Tool Holder must overcome the light
force of the
Continuity Springs.
The Safety Switch is inside the Upper Tool Holder.
