Cycle Parameter Display

The machine is capable of displaying many parameters, not all of which can be shown on the screen at the same time. 
Pressing the CYCLE PARAMETERS button will toggle the display of the parameters. The following is a list of available 
parameters and the corresponding abbreviations as they are shown on the display.

Machine Parameters

Machine parameters control the behavior of the machine, the type of optional equipment, which may be installed, and the 
language in which to communicate with the operator. Modifying machine parameters may adversely effect the behavior of 
the machine. Prior to making changes care should be taken to ensure a complete understanding of each parameter and 
its effect on the operation of the saw. 

To enter machine parameters toggle the main power off and on. Press the MACHINE PARAMETERS AND MACHINE 
START buttons in that order.

To move from parameter to parameter press the HEAD DOWN or HEAD UP LIMIT button. Notice the horizontal arrows 
under the button depicting forward or backward scroll thought the parameter list.  To change the value of a parameter use 
the HEAD DOWN LIMIT button. Notice an up arrow under the button depicting an upward change in value. The button to 
the right of the HEAD DOWN LIMIT clears the parameter value.
