Installation & Adjustment Procedures
Arcing Horn Adjustment
If arcing horns are supplied and adjustment is required proceed as follows:
•
Operate Switch.
•
Blade should make light to firm sliding contact along the straight portion of the horn
until the switch is fully closed.
•
Readjustment of the arcing horn can be done by grasping it firming and bending until
the action described above is achieved. The arcing horns should have light pressure,
not forcing the blade into place when closing. See Figure 7.
