Backhoe attachment
WARNING
Avoid injury!
Read and follow the instructions in this manual.
Failure to comply could result in death or serious injury.
W1212A
The following instructions do not cover all possible condi-
tions of use of the backhoe attachment. They only consti-
tute basic information to enable the machine to be oper-
ated correctly.
NOTICE:
To achieve an optimum balance between ma-
chine performance and fuel economy, operate the ma-
chine at
1600 - 1700 RPM
.
NOTE:
The first time it is operated, maneuver the machine
in a clear area and at low speed.
Make sure that no other person is in the working range of
the machine.
Never dig near or under the stabilizers, since the machine
could fall into the excavation.
When working in an area of reduced visibility, for example
next to a building, place a safety barrier and sign panels
to prevent anyone coming near the machine.
The backhoe attachment will dig more quickly if the work
cycle is short and uninterrupted.
Organize your work site so as to obtain a smooth work
cycle.
If you try to use the backhoe bucket for digging too wide
a trench, you may cause a stall situation (where the dip-
per control lever is tilted towards the rear but nothing hap-
pens).
The hydraulic system main relief valve makes a noise
when a hydraulic stall occurs.
This overload causes the work cycle to be prolonged and
it increases the hydraulic fluid temperature.
