ISO/SAE switch
The ISO/SAE switch allows the operator to select either the ISO or SAE excavator control pattern.
Before you operate the excavator controls check the SAE indicator lamp to see which control pattern has been
selected. The indicator lamp illuminates to show that the SAE controls pattern is selected. If the lamp is not
illuminated the ISO controls pattern is selected. Operate the machine slowly until you are familiar with the
pattern selected.
The excavator controls consist of the excavator levers and the swing pedal.
The excavator levers are spring loaded to the central position. In this position related services will not operate.
The speed and movement of the associated hydraulic function depends on how far you move the lever. The
further you move the lever, the faster the action.
