Grading adjustmets
Grader is equipped with a remote controller, which allows to control all actions with one 2-way section valve. Controller,
it’s fastener and power socket are
added to the base machine.
Operating the controller:
-
Attach electricity from the base machine with a 3-pin power socket.
-
Turn the controller on with a green START-button (must be done every time the power supply stops).
-
Operate controllers’ buttons simultaneously with the base machine’s directional valve.
-
When transferring the grader turn off the controller with a red STOP-button.
-
The warning light of the controller lights up 100 hours before the batteries are empty.
-
If there is an error in controller, recode it.
Functions of the controller (picture 3):

Main blades of the grader lift/descent with buttons 1 and 2. When transferring the road grader keep main
blades all the way up.
-
Main blades
’
tilt can be adjusted with buttons 13/14 and 11/12. Use slope pointer to check the slope of the
grader.
-
Windrow blade lifts/descents with arrow buttons of controller box. When transferring the road grader keep
windrow spreader all the way up.
-
Windrow blade’s ti
lt can be adjusted
with buttons 5/6 and 7/8. Windrow’s height depends on the depth of the
grading. If there is sand coming out of windrow blade, it is too close to the road. Windrow spreader is adjusted
