Notes to the following Maintenance Instructions
| Important supply functions
are monitored |
Some components of the machine's fluid system are monitored electrically. This is achieved, for example, by float switches in fluid containers or differential pressure measuring devices on filters. If,during operation, a measured value exceeds the set limit value or switching point, an error message appears on the main operator panel. |
| Error messages |
Error messages are messages that cause the machine to be shut
down since safe operation can no longer be guaranteed. The error must therefore be eliminated immediately. The machine must not be operated again until the error is eliminated! |
| Pre-warnings |
Pre-warnings are maintenance requests that do not cause the
machine to shut-down immediately. Rectify the cause of the message as quickly as possible! This will prevent the next limit being exceeded, an error message being generated and the machine
being shut down. |
| Skilled maintenance is vital |
Inadequate or improper maintenance can cause equipment failures and affect the operating safety and durability of the machine. It is recommended that maintenance is carried out only by trained personnel. |
| Warranty limits |
The contractually agreed warranty does not relieve the machine owner of the obligation to rectify errors immediately. HELLER shall not be responsible for damage caused by inadequate maintenance. |
|
Whenever maintenance work is carried out, the instructions in the Chapter on "Safety" in these Maintenance Instructions and the applicable safety regulations must always be followed and strictly adhered to! |
| Observe particularly the instructions in Section 4.2. This Chapter describes preparatory and conclusive safety measures for work in the danger zone of movable machine parts and automatically operated devices. |
