7.2.2 Checking the hydraulic uid level
DAMAGE
Material damage due to operation without hydraulic uid
Dropping below the minimum hydraulic uid level can cause the operating temperature to rise, lead to
air accumulating in the system and to the hydraulic pump failing due to cavitation.
►
During initial commissioning and after each opening of the hydraulic system
►
Fluid level too low: top up hydraulic uid.
1. Check the uid level in the tank.
The level of the hydraulic uid should be within the cross marking on the tank.
Fluid level too low: top up hydraulic uid.

7.2.3 Replacing the hydraulic uid
The hydraulic system is switched off and secured against unintentional restart.
The system is pressureless.
The work environment is clean.
1. Wait until the system has cooled down.
2. Place a suitable receptacle under the hydraulic power pack.
3. Open the tank lling screw.
4. Tilt the hydraulic power pack so that the hydraulic uid can completely ow out of the tank into the
receptacle.
5. Filter fresh hydraulic uid (mineral oil in accordance with DIN 51524). Recommended lter: 10 µm.
6. Pour the ltered hydraulic uid into the tank.
Use the cross marking on the tank to read off the maximum permitted amount. The level of the
hydraulic uid should be within the cross marking.
