FOREWORD

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.

DESIGNATED USE

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.

NOTE:

by using appropriate lubricants, the excavator can work with temperatures ranging from -20 °C to + 40 °C (-4 °F to + 104 °F). For the correct operation of the machine in this temperature range, please refer to the table of lubricants contained in this manual

DANGER
Using the excavator and its attachments differently
from the way described in this manual will be
deemed as improper use. Please find below some
examples of improper use of the excavator:
– for lifting or transporting persons;
– as a working platform;
– for pulling slung loads;
– for driving in posts, supports, sheet-piles, without
the attachment being approved for this purpose.
Improper use may cause injury or life-threatening
risks for the operator and for other persons
