Case CX20B CX22B CX27B Mini Excavators Operator’s Manual 84287272 – PDF DOWNLOAD

• The crawler mini excavators are hydraulic machines. They consist of two main parts: the upper frame and the lower frame. These components are coupled by means of a slewing bearing which enables the upper frame to slew with respect to the lower frame.
• The boom, tanks, radiators, counterweight, diesel engine and all hydraulic components for the operation of the excavator are fastened to the upper frame. The lower frame is equipped with crawlers which can be made of rubber or metal and with a blade for levelling operations.

• The machine has been built in accordance with state-of-the-art standards and the recognized safety rules. The machine must be used in accordance with its designated use, by observing the safety and precautionary rules and by strictly following the operating instructions.
• Any functional disorders, especially those affecting the safety of the machine, should therefore be rectified immediately. The Excavator is intended to be used in digging and loading operation (with bucket), ground levelling (with blade) and use of hydraulic hammer to break concrete or other solid material.
