You have a Terex Schaeff machine on the stand with weak steering or a lift that has lost its push, and a gauge in your hand. This service manual gives you the test ports, the setting values and the adjustment points. It covers the SKL and SKS series, the HML mobile excavators and the HR compact excavators.
This is the TEREX | SCHAEFF edition 01.2006: three factory folders bound into one PDF and split into twelve groups. They run from Technical Data and Diesel Engine through Setting Instructions, the Electrical System wiring diagrams and the Maintenance inspection plans. Sheets are printed in German, English and French.
Guessing at hydraulic settings on an older Schaeff gets expensive fast. Check the data sheet and hydraulic diagram for your exact model first, so the valve or seal kit you order is right the first time.
