Adjusting Limit Switches
4-2 KVAL EP-1 Operation/Service Manual
Adjusting Limit Switches
If a machine suddenly stops in mid cycle, check the limit switches. A
worn limit switch arm or a mis-adjusted limit switch is more than
likely the cause. Depending on the model of limit switch on your
machine, the
pre-travel (amount of movement from the limit switch
arm’s resting position to the position at which the switch actuates –
with a “click”) is either 5 or 20-degrees. The EP-1 has three 20-
degree switches.
If the arm is moved to the full extent
of its travel and you do not hear the
limit switch “click”, the switch needs
to be adjusted. Use the set screw on
the limit switch arm and adjust the
arm to activate at the desired degree of
rotation (see illustrations below).
The EP-1 has three limit switches that
have 20-degrees of pre-travel
• Drill Retract
• Drill Extended
• Router Stop (Signals that the
Router is out of position so
Drill can move forward.)
