Test the Down Limit Switch, the
Pothole Limit Switches and the Level
Sensor
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.
