GENERAL INFORMATION
Foreword
The safety instructions and the rules and regulations for the use of excavators given in these operating instructions
apply to the excavators mentioned in this documentation.
It is the responsibility of the owner(s):
To ensure that local, regional and national regulations are observed,
To observe the bodies of rules (laws, regulations, guidelines, etc.) stated in the operating instructions to en-
sure safe handling of the equipment,
To ensure that the operating instructions are available to the operating personnel at all times and that the in-
formation, such as notes, warnings and safety rules and regulations, are followed in all points.
The data in the operating instructions apply for all models. Differences are highlighted (e.g. K008-5 or U10-5).
The terms "front" and "direction of travel" refer to the view of the op-
erator when seated on the operator's seat. Forward direction of trav-
el means that the dozer is at the front when driving forwards as
shown in the figure.
The symbols for operating and safety instructions are listed under "Safety symbols" (page 15).
EC Declaration of Conformity
Your copy of the EC declaration of conformity is delivered with the machine. Keep the EC declaration of conformity
in a safe place and show it, if requested, to the responsible authorities. Should the EC declaration of conformity
be lost, contact your local KUBOTA Dealer.
The CE marking is located on the type plate. If the machine is modified or retrofitted without the approval of the
manufacturer, the safety of the machine may be affected, thus rendering the EC declaration of conformity invalid.
