PREVENT ACCIDENTS
The majority of accidents and injuries which occur in the workshop, at the worksite or on the road, are caused
by the failure of some individual to follow simple and fundamental safety rules or precautions. For this reason
most accidents can be prevented by recognizing the real cause and taking the necessary precautions, before
the accident occurs.
Regardless of the care used in design and construction of any type of equipment, there may be conditions
that cannot be completely safeguarded against, without interfering with reasonable accessibility and efficient
operation.
A careful operator and / or technician is the best insurance against accidents.
The careful observance of this single safety rule would be sufficient to prevent serious injuries:
Never attempt to clean, lubricate or adjust a machine while it is in motion.

SWARNING S
Before carrying out any maintenance operation, adjustment and or repair on machines equipped with attach-
ments, controlled hydraulically or mechanically, make sure that the attachment is lowered and safely set on
the ground. If it is necessary to have the equipment partially or fully raised to gain access to certain items, be
sure the equipment is suitably supported by means other than the hydraulic lift cylinders, cable and /or
mechanical device used for controlling the equipment.

FOREWORD
Loader backhoes B90B - B90BLR - B100B -
B100BLR - B100BTC - B110B - B110BTC - B115B
have been designed to perform most earth-moving
operations.
If you use this machine for duties involving the use
of attachments, accessories, or special tools, con-
sult your Dealer to make sure that the adaptations or
modifications carried out are in conformity with the
machine’s technical specifications and with current
regulations on safety.
Any modifications or adaptations which are not
approved by the manufacturer may invalidate the
machine’s original conformity with safety require-
ments.
The machine must be used according to its intended
use, respecting the safety and precautionary rules
and strictly following the operating instructions.
Any functional disorders, especially those affecting
the safety of the machine, should therefore be recti-
fied immediately.
The manufacturer/supplier cannot be held responsi-
ble for any damage resulting from unintended use.
The risk involved in such misuse lies entirely with
the user.
The current Operator’s Manual is the user’s guide
for correct run-in, use and maintenance of the
machine.
SDANGER S
A different use of the excavator or of its working
equipment:
- for lifting or transporting persons;
- as working platform;
- for lifting loads without the attachment being
approved for this purpose;
- for pulling loads;
- is considered unintended use.
Unintended use may cause injury or life-threatening
risks for the operator and for other persons.
SDANGER S
It is absolutely forbidden to tamper with and/or
change the setting of any of the hydraulic system
valves to avoid damaging machine components,
with a consequent risk for personal safety.

SECTION 00 - SAFETY RULES 5
Carefully read this Operator’s Manual and store it in
the cab for quick location and reference.
Instructions concerning safety, operation and main-
tenance have been developed to permit safe serv-
ice and repair of this machine without any risk.
In the event of queries or suggestions relevant to
your machine do not hesitate to address to your
Dealer.
Dealers have qualified and trained personnel at dis-
posal as well as Original Spares, means and equip-
ment suitable to carry out all necessary
maintenance.
Any modifications or adaptations which are not ap-
proved by the manufacturer may invalidate the ma-
chine’s original conformity with safety requirements.
IMPORTANTE: the engine and fuel system on your
machine are designed and built to government
emissions standards. Tampering by dealers, cus-
tomers, operators and users is strictly prohibited by
law. Failure to comply with this prohibition could
result in government fines, rework charges, invalid
warranty, legal action and possible confiscation of
the machine until rework to original condition is
completed. Engine service and/or repairs must be
carried out by a certified technician only.
NOTA: each machine is supplied complete with a
copy of this Manual. Descriptions and illustrations
provided herein are not binding. The Manufacturer,
provided that the basic characteristics of machine
types described and shown in this Manual remain
the same, reserves the right to change compo-
nents, parts and accessories supplied without any
commitment to timely update this publication; and
this any time it deems it convenient for improve-
ment purposes or due to commercial or manufac-
turing requirements. For exact information, please
