INTRODUCTION:
- This manual includes information for the installation, maintenance, and minor repair of
H1 tandem pumps. It includes a description of the unit and its individual components,
troubleshooting information, and minor repair procedures. - Performing minor repairs requires the unit to be removed from the vehicle/machine.
Thoroughly clean the unit before beginning maintenance or repair activities. Since dirt
and contamination are the greatest enemies of any type of hydraulic equipment, follow
cleanliness requirements strictly. This is especially important when changing the system
filter and when removing hoses or plumbing. - A worldwide network of Sauer-Danfoss Global Service Partners is available for major
repairs. Sauer-Danfoss trains and certifies Global Service Partners on a regular basis.
