Instruction Manual
Warning
Information contained in this manual is not contractual.
Instructions concern regular maintenance only.
It is forbidden to carry out any modification whatsoever on equipment.
Only use original parts.
Safety Precautions
The operator should be fully aware of the contents of this manual.
This manual must be available to the operator at all times.
Furthermore, operate this shear in a safe working environment.
Mounting on Carrier
The operator must comply with the “Instructions for use” contained in this manual, as well as
those concerning the carrier, such as carrier weight, pressure, flow and connections.
Before any operation is carried out on the equipment, ensure that the residual pressures are
released and cooling in the hydraulic circuit and mechanical parts has been completed to
avoid loss of any oil.
Ensure that all hydraulic components conform with standards in force.
Use
The operating zone must be made secure and well-lit.
If the carrier is operating in an area where there is a risk of falling objects, the cabin should be
equipped with an approved fall over protection system (FOPS).
Before starting work the operator must inquire about the presence of electric cables, gas or
water pipelines, and any other possible source of danger in the operating zone.
If the carrier has no cabin, it is highly recommended to provide a protective grid at the front of
the carrier and reduce emission of dust (water spray).

Instruction Manual
Handling and Transportation
Please see the above description of the attachment in this manual for an indication of weights
and sizes. Given the attachment’s weight and size, it must be handled and transported only
by specifically skilled personnel. If the operator employed to handle the attachment does not
have a complete view of the attachment to be moved, the assistance of a second operator is
needed on the ground but out of the carrier’s range of action. In the attachment there are holes
for the insertion of lifting hooks. Make sure that these hooks are secured firmly to allow you to
proceed to move the attachment.
Attachment Installation
!
CAUTION
Before proceeding to install the attachment you need to make sure that
the attachment itself is intact as it might have been damaged during
transportation.
It is especially important to check that the plumbing is intact and the
hydraulic connections are firmly attached.
NOTICE
The attachment must be installed in a space large enough to allow the
necessary operations to be carried out in complete safety.
!
CAUTION
The attachment is not recommended to be used at ambient temperatures
below 3°F (-16.5°C) or above 114°F (45.5°C).

Instruction Manual
Assembly and Disassembly
!
CAUTION
While being assembled, place the attachment on the ground and park the
excavator in the service position, according to the instructions in the
carrier operational manual.
If our attachment is supplied without a bracket cap, it is up to the client to
fit it with a suitable cap complying with current safety standards.
Assembly
The bracket cap provided in our attachment is equivalent to that supplied for a standard bucket
of the carrier on which this attachment is mounted. For a detailed explanation on mechanical
connection please refer to the instruction handbook of the carrier in question.
The hydraulic system shall be connected by linking the two hydraulic fittings for each circuit
(rotation, shear), on the equipment to the corresponding fittings on the carrier.
!
CAUTION
Verify that the couplers for each circuit of the attachment are connected
to the proper excavator circuit. Direction of excavator hydraulic circuit
flow does not matter.
!
CAUTION
DO NOT USE THE ATTACHMENT WITHOUT FIRST CHECKING THAT THE
HYDRAULIC PRESSURE AND FLOW OF THE EXCAVATOR IS SET TO
WHAT IS REQUIRED FOR THE ATTACHMENT BEING USED.
19398510
13
Instruction Manual
Disassembly
When disassembling, the attachment must be laid firmly on the ground.
a. Park the excavator in the service position according to the instructions in the
carrier operation manual.
b. Make sure that the hydraulic system connected to the attachment is no longer
under pressure.
c. Remove hydraulic connections between the excavator and attachment.
d. Uncouple the bracket cap pins of the attachment as described in the excavator
instruction handbook.
Start-up and Use
During operation the operator must stay on board the excavator, in the position recommended
by the manufacturer. Bystanders must not stand within a 100 foot range of the excavator when
it is being operated.
Maintenance and Repair
!
CAUTION
Any operation requiring the operator’s direct participation (inspections,
maintenance) shall be carried out when the machine is not working and
the equipment is steady on the ground.
!
CAUTION
Maintenance and repair of the attachment should only be carried out by
qualified personnel.
!
CAUTION
Thin sprays of high pressure hydraulic liquid can penetrate skin. DO NOT
use your finger to search for any leaks. DO NOT place your face close to
suspected leaks. To highlight signs of hydraulic leaks, place a piece of
cardboard close to the suspected leaks and then inspect the cardboard.
If the hydraulic fluid penetrate your skin, immediately call for medical
help.
14
19398510
Instruction Manual
The following inspections and maintenance should be carried out carefully and regularly for
safe working:
EVERY TIME THE MACHINE IS USED:
Ensure that there are no hydraulic leaks and the plumbing is in good condition.
EVERY 8 HOURS OF USE OF THE EQUIPMENT:
Check the tightness of the screws on the blades.
EVERY 40 HOURS OF USE OF THE EQUIPMENT:
Check that all the screws are undamaged and securely tightened according to the enclosed
table at the end of this manual.
!
CAUTION
Should the attachment break down, contact the dealer directly or in any
case use qualified personnel. Neither the attachment nor its functionality
may be modified in any way.
19398510
•
With reference to UNI ISO 4406, THE LEVEL OF FLUID CONTAMINATION MUST
BE IN CLASS 19/15 OR BETTER;
•
THE EXCAVATOR HYDRAULIC FLUID MUST BE FILTERED IN ACCORDANCE
WITH UNI ISO 7744.
•
The temperature of the oil in use SHALL NEVER EXCEED 158°F (70°C).

Instruction Manual
Rotation Gearbox Maintenance
The oil should be changed for the first time after 100 operating hours and afterwards every
2500 hours or at least every 12 months. These periods may be varied to suit individual cases
according to the actual operation conditions. When the oil is changed, we recommend that the
inside of the casing is also flushed with a suitable liquid recommended by the lubricant
manufacturer. To avoid leaving a sludge deposit, the oil should be changed when the
reduction motor is hot. We recommend that the oil level is checked at least monthly. If more
than 10% of the oil needs to be added, thoroughly check that the unit is not losing oil. Avoid
mixing different types of oil. This includes oils both of the same and different makes. Avoid
mixing mineral and synthetic oils.
DRAINING THE OIL:
Position the attachment in an horizontal position.
Place a container under the drain plug.
Unscrew the drain plug and drain all the oil. Be careful the oil could be hot.
To assist drainage, perform the operation with the gear motor still hot.
Screw the drain plug back on.
FILLING:
Position the attachment in an horizontal position.
Unscrew the filler cap.
Fill with approximately 1/2 gallon (when topping up, fill the gear motor to the oil level
plug).
Screw the filler cap back on.
Oil used on delivery of the machine: AGIP SIGMA SAE 30.

Greasing
EVERY 4 HOURS OF OPERATION,
Grease points B, C with 5-6 squeezes of the grease gun. Move away from the equipment and
use the excavator opening and closing controls to close and open the jaws 3-4 times, then
grease again.
EVERY 40 HOURS OF OPERATION,
Grease the rotation movement at point D, squeeze the grease gun 5-6 times. Move away from
the equipment and use the excavator controls to rotate it for 10 seconds, then grease again.
EVERY 80 HOURS OF OPERATION,
Grease the rotation movement at point A, squeeze the grease gun 4-5 times. Move away from
the equipment and use the excavator controls to rotate it for 10 seconds, then grease again.
!
CAUTION
More frequent lubrication is recommended in the tropics, in very humid
areas, in dusty environments, in places with significant levels of
impurities and with wide temperature fluctuations.
