INTRODUCTION AND SAFETY PRECAUTIONS
INTRODUCTION
The E265B / E305B excavator is a hydraulically operated machine. It consists of an undercarriage fitted with
tracks and a swing bearing which supports the upper frame. The upper frame supports the attchment, the
engine, the hydraulic components, the cab, the fuel tank and the counterweight. When the operator activates
the controls (pedals/levers), the hydraulic pumps, operated by the engine, sucks the oil from the tank, sending
it to the control valve which sends the oil to perform the request operation. A cooling system mantains the
hydraulic oil at normal operating temperature.
NHC0120
INTENDED USE
WARNING
Do not use the excavator for operations which are foreign to its specifications and not included in this manual
in order to prevent serious injury to persons or damage to the machine. The manufacturer/dealer is not
responsible for damage caused by improper use.
The excavator has been designed to carry out digging and earth moving operations through the use of a
bucket. Operations that involve the use of hydraulic hammers or crushers are also possible. Other operations,
such as moving suspended loads, are only possible if the specific variant approved by the manufacturer is
present.
Using the excavator and its equipment for different operations, such as, for example, towing, transporting and
lifting people, is considered inappropriate and is prohibited.

INTRODUCTION AND SAFETY PRECAUTIONS
WELDING REPAIR INTERVENTIONS
• Welding repair interventions must be performed
only by a certified welder with sufficient experi-
ence. Also, appropriate safety rules must be
implemented by all the personnel involved in the
operations. The duration through time of the weld-
ing depends upon the quality and the accuracy
with which the operation is performed.
- Identify first all the fracture points and the zones
in which welding is required.
- Clean accurately the zones involved.
- Remove all paint and inspect the parts with pen-
etrating liquid or a magnetic particle tester.
- Move the starter switch into position "OFF" and
wait for 4 seconds to cut-off electricity from the
system.
- Disconnect the negative terminal (-) from the
battery.
- Connect the ground cable of the welder at least
1 m from the component to be welded.
- Make sure that the ground cable is NOT con-
nected to a seal or bearing and that there are
noo seals or bearings between the ground cable
and the part to be welded.
- Avoid welding pieces at low temperature i. e.
below 16 °C. If necessary, warm-up the part
involved prior to welding it.
- Remove paints from all surfaces prior to warm-
ing-up or welding. Painted surfaces, when
warmed-up or when welded, can generate toxic
fumes.
- Use appropriate masks or protective glasses.
- Wear gloves and adequate clothing to protect
the skin.

Oil replacement
WARNING
You are reminded that the travel reduction units and
their oil can reach, during operation, high
temperatures, thus it is indispensable to protect
body and limbs with appropriate clothing, glasses
and protections, since there is a danger of burns
and personal injuries.
Loosen slowly the threaded plugs for the inspection
of the oil level in the reduction units. This is to allow
a slow bleeding of the pressure created inside the
final drives.
When changing the oil, stand in a out-of-line position
with respect to the side of the reduction units and
always wear protective glasses.
The operation for the alignment of the reduction
units filling and level check plugs, described here
below, must be made with an assistant on the
ground. However, this assistant must always stand
away from the field of action of the machine.
Never perform maintenance or inspection
operations on the cirtuits of the travel motors on
gradients. They are strongly pressurised due to the
effect of the weight of the machine.
• Park the machine on a level surface.
The reduction units should be positioned as to
have the plugs (1), (2) as shown.
- Rest the bucket to the ground.
Observance of this position is essential to proper
