Hydraulic control unit adjustment

Before starting to use the TCE 4540 it is necessary to
adjust some valves in the hydraulic control unit.
+
The capacity adjustment valves (1) with knobs regu-
late the lifting/lowering and entering/exiting speed
of the mounting tool. Initially they are pre-calibrated
as open, meaning that they are at maximum speed,
and they can be adjusted by the operator.
+
The pressure relief valve (2) checks the pulling
pressure of the mounting tool on the bead. Initially it
is pre-calibrated at a pressure of 80 bar. The opera-
tor can adjust it anywhere in the 80 bar to 100 bar
range, based on tyre hardness.
+
The safety valve (3) is pre-calibrated at a pressure
of 100 bar (maximum pressure). This valve is not
adjustable.
