3.2. INITIAL OPERATION
The machine is ready for operation after a test run. The following safety checks are necessary prior to initial
operation of the compactor:
DANGER
The operating personnel must be familiar with machine handling and observe
the safety instructions !
All service openings must be closed !
Make sure there is no person inside the charge box before starting
operation !
The discharge door must be locked !
The maintenance door of the hydraulic unit must be closed during operation !
1 ........ Connect the compactor to electrical supply.
2 ........ Switch on main switch.
3 ........ Unlock the EMERGENCY-OFF button (on both sides).
4 ........ Push start button.
The ram face must move backward within 5 seconds.
Immediately switch off the motor if it fails to do so, since
the pump will not be lubricated once the motor takes the
wrong direction. Reverse poles of the plug in the machine
socket by switching the pole changer.
5 ........ After starting the motor, the ram face will alternately move
forward and backward. For this purpose, two hydraulic cylinders
alternately move up and down. The movement of the hydraulic
cylinders is reversed by means of a hydraulic control unit. For protection of the hydraulic unit, the power
unit is equipped with a time lag relay, which automatically stops the hydraulic operation after a set period of
time, at any point bet-ween 0 and 12 minutes.
6 ........ Charging of the waste may continue up to the point where the ram face fails to clear the charging
opening.
CAUTION
Never leave the operation panel unattended during the compaction process;
the machine must be switched off immediately in case of emergency !
The panel may be left unattended only after operation is discontinued !
