Setup & Operation
2.12 Hydraulic Control Operation
The hydraulic control levers become operational when the main switch located on the starter box is
in the “1” position the contacts at the bottom of the carriage touch the power strip on the frame tube.
The hydraulic control levers will only work when the cutting head is close enough to the front end of
the mill to touch the power strip.
The power supply wire of the electric box installed on the front of the hydraulic control box must be
attached to the electric grid, with the switch turned to position “1” (the white indicator marked
“voltage” willturn on).
DANGER!
The power control box of the hydraulic motor pumps as well
as the starter box must be powered with a connector equipped with
a secure circuit (current change switch).
The hydraulic power supply turns on automatically by raising or lowering of the control levers. After
putting the control levers in neutral the feeder drive works still by 5 seconds. It prevents the hydraulic
motor pumps from frequently starting and overheating.
After taking all of the above steps, if the hydraulic system still does not work properly you must make
sure that the off switch on the starter box is in position “1”, and the voltage indicator is lit up. Next you
must check to see whether the safety switch on the left side of the operator box is turned on. Motor
rotation may also need to be checked (hydraulic pumps can only run in one direction). You can adjust
the motor rotation with a screwdriver by adjusting the switch located on the left side of the electric
box mounted on the hydraulic box.
