9. Positioning the PumP during oPeration
The pump oil tank is closed with the ventilation screw during operation and so not sealed. To prevent
hydraulic oil from escaping or overflowing, the pump must not be used when excessively tilted (fig. 5).
The side viewing window on the pump housing serves for visual inspection.
After intensive use, foam may form on the oil surface. Excessive tilting of the pump can cause foam to
escape through the ventilation screw at the tank opening
• Consequently, where possible, ensure horizontal positioning of the pump.

10. oil change
Regular maintenance of your hydraulic pump can extend the service life of the seals and the moving
parts. To remove deposits and small suspended particles from the tank, the hydraulic oil must be
replaced completely for frequent use of the hydraulic pump. The first oil change should be performed after
approximately 50 operating hours, and then annually.
