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 Tools downward motion reverses immediately and returns to its Up position.
Non-conductive mode
The Upper Tools 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 machines 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.
