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 indi-
cator 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 hydrau-
lic box.
