Test the Up Limit Switch
DINGLI requires that this procedure be
performed every 250 hours or quarterly,
whichever comes first.
Maintaining the limit switches is essential to
safe operation and good machine
performance.
Operating the machine with a faulty limit switch
could result in reduced machine performance
and a potentially unsafe operating condition.
Perform these procedures with the machine on
a firm, level surface that is free of obstructions.
