Controlling The Sawmill
LT70AC Remote sawmills are operated with the controls located on the front panel of the
control box. Most of the sawmill head and bed functions are performed with two joysticks
(left and right). The joysticks can work in two control modes:
Head Mode
Bed Mode.
In HEAD mode the joysticks control the following head functions: saw head up/down
operation and forward/reverse movement, blade guide arm in/out movement and Auto
Bump-Up function. In sawmills equipped with the debarker option, the right joystick can
also be used to move the debarker in or out.
In BED mode the joysticks can be used for log handling functions such as: log loading,
turning, clamping and levelling. Also, optional log handling equipment (e.g. log infeed
deck option) is operated in this control mode.
4.2.1
Performing Log Handling Functions
To perform any of the log handling functions, first check if the yellow BED light is lit. If this
light is on, the BED mode is active and you can operate all log handling functions. If it is
off, push the white HEAD/BED button
.
The use of the joysticks for performing the bed functions can be divided into three groups:
Neither of the top buttons on the joysticks (neither on the left joystick nor on the right
one) is pressed
(group No. 1).
Either of the joystick top buttons (left or right) has to be pressed and held
(group No. 2).
Both joystick top buttons have to be pressed and held
(group No 3).
