Introduction
The RC² 2600 CL, RC² 2600 LSL and RC² 3100 CL models
perform mowing jobs with higher yield and superior quality.
These rotary cutters are used for citrus orchards cultivation
or similar to eliminate stubbles and also to provide services that
need a great speed to execute.
The RC² 2600 CL and RC² 3100 CL models work in a central
or lateral position related to the tractor center; the RC² 2600 LSL
model works in a lateral or super lateral position. All these models
work under the tree canopies to completely clean the orchards.
The rotary cutters are supplied with four reversible
DUROMARK blades (double cut), which are heat-treated and
offer a greater durability.
This operator's manual contains the necessary information
for the best performance of this rotary cutter. The operator must
carefully read the entire manual before working with the equipment.
Also, read and understand the safety recommendations.
For any further clarification or in the event of technical
problems that may arise during the service, consult your dealer
and the Technical Support department of the factory. They can
ensure the fully functioning of your TATU rotary cutter.

Transportation over truck or trailer
To the operator
Marchesan does not advise the equipment traffic on highways, because this
practice involves serious security risks in addition to being prohibited by the
current existing traffic law. The transportation for long distances should be
done on truck, trailer or other by following these safety guidelines:
• Use adequate ramps to load or unload the equipment. Do not make the loading
on ditch banks, it can cause a serious accident.
• When lifting with a hoist, use the appropriate points to lift.
• Fasten the moving parts that could get loose and cause accidents.
• Underpin the equipment wheels appropriately.
• Use chock blocks and safety chains to secure the equipment to the truck or
trailer during the transport.
• Stay away from the straps, cables or chains that are used on the load.
• Make sure the SMV (Slow Moving Vehicle) sign, and all the lights and reflectors
that are required by the local highway and transport autorithies are in place,
are clean and can be seen clearly by all overtaking and oncoming traffic.
• After 8 to 10 km transporting, please inspect the load condition. Repeat this
procedure every 80 to 100 km. Give more attention when transporting the
equipment on rough roads, slopes and other adverse conditions.
• Always be careful with the load height, especially when passing under electrical
power lines, bridges and others.
• Check all laws and regulations regarding the height limits and load width while
transporting the equipment to the truck or trailer. If necessary use banners,
lights and other devices in order to give adequate warning to the other drivers.

To the operator
Working safety standards
It is important to have knowledge not only about the functioning, operation of the
equipment and its technology, but also the working legal aspects when using the equipment,
such as: safety standards, operator's manual and working safety.
The equipment and tools used on the rural area must be properly handled, otherwise
health and safety of involved personnel may be compromised.
The operator must be capable and authorized to operate the tractor, meaning that
that person must comprehend the functioning instructions of the tractor and know about
the safety standards regarding the job that will be performed.
The Ministry of Labor and Employment created safety standards that aim to decrease
the risk of accidents that may occur to the rural worker. Related to the subject of agicultural
machines and equipments, we specifically cited the NR 06, NR 12 and NR 31 standards.
Regulatory Standard - NR 06:
• For purposes of applying this Regulatory Standard, Personal Protective Equipment
(PPE) is considered any device or product that is worn by an individual worker for protection
against risks that could threaten safety and health at work.
Regulatory Standard - NR 12:
• This Regulatory Standard and its annexes provide technical references, basic
principles and protective measures to ensure the health and physical integrity of workers
and establishes minimum requirements for the prevention of accidents and occupational
diseases in the design stages and use of machinery and equipment of all kinds, and also
to its manufacture, importation, trading, exhibition and cession in any way. It is understood
as using phase the construction, transportation, assembly, installation, adjustment,
operation, cleaning, maintenance, inspection, disabling and dismantling of machinery or
equipment.
Regulatory Standard - NR 31:
• This Regulatory Standard has the purpose to establish the precept to be applied on
the organization and on the working environment, in order to make compatible the planning
and development of agriculture, livestock, forestry, forest exploration and aquaculture with
safety on the working environment.
