If work is to be done on the parts carrying voltage, a second person has to be
consulted who disconnects the current supply if necessary.
System parts and pressure hoses must be depressurized before the beginning of
any repair work.
Even if the machine is switched off, there could still be pressure in the hydraulic
accumulator!
There is a danger of injuring the eyes by hydraulic oil squirting out.
Check the oil level of the hydraulic system before each starting in order to avoid
damages on the pump.
The oil level has to be between the two marks on the oil level measuring bar.
Replace defective hydraulic hoses immediately.
