CAUTION
If there is a physical obstruction or stop that prohibits the use of the maximum stroke
length, then an external limit switch MUST be installed to interrupt the Linear Actuator's
movement before contact is made with the physical obstruction or stop.
Failure to use an external limit switch will damage both the Linear Actuator and the
web guiding mechanism.
If there is no physical obstruction to travel, then the nonadjustable, internal limit switches
may be used in their default position for maximum stroke length.
