Introduction
The GAPCW-EP disk harrow was designed to work in
any kind of soil, with excellent application on the soil
preparation for annual crops, sugar cane etc.
The heavy-duty structure with proper dimensioning is
made of bent steel plates joined by a good penetration
weld and fine finishing, with tough parts in the load
concentration.
The GAPCW-EP transportation is made through an
efficient wheelset system composed by tires and hydraulic
cylinders, which allows long-distance transportations.
This operator's manual contains the necessary
information for the best performance of this harrow. The
operator must carefully read the entire manual before
working with the equipment. Also, read and understand
the safety recommendations.
For any further explanations or in the case of technical
problems that may arise during the service, consult your
dealer and the Technical Support department of the
factory. They can fully ensure the functioning of your
TATU disk harrow.

Working safely
Be careful with the environment
Dear operator!
Respect the ecology. Do not throw trash away. This gesture
of goodwill helps to protect our environment.
Products such as oil, fuel, filters, batteries and others are
spilt over the soil and can penetrate to the underground layers,
compromising nature. Ecological and conscious disposal of them
should be done.
This equipment is simple to operate, requiring however the
basic and essential cautions to its handling.
Always keep in mind that safety requires constant attention,
observation and prudence during work, transportation, maintenance
and storage.
• Security aspects must be carefully observed, to avoid
accidents.
• This symbol is a warning used to prevent accidents.
• The instructions under this symbol refers to the safety of the
operator, mechanician or third parties, therefore they should
be carefully read and observed. If the safety instructions are
not being followed, a serious accident or even death may
occur.
Read and understand the information before making any
adjustment or maintenance.
Have extreme caution when operating with the power take-off
(PTO), which you should not get closer during operation.
When hitching the equipment to the tractor, use a chain to
lock the equipment drawbar to the tractor hitch bar. This procedure
will prevent a possible rupture of any hydraulic hose or breaks on
the hitching system, what would make the equipment tilt up.

Transportation over truck or trailer
To the operator
Marchesan does not advise the equipment traffic on highways, because this
practice involves serious security risks and it is prohibited by the current traffic
law. The transportation for long distances should be done on truck, trailer or
others 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.
• Underpin the equipment properly.
• Use chock blocks and safety chains to secure the equipment to the truck or
trailer during the transport.
• 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,
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 on truck or trailer. If necessary, use banners, lights
and other devices, in order to give adequate warning to the other drivers.

Working safety standards
It is important to have knowledge not only about the functioning, operation of the
equipment and its technology, but also about 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 the
person must comprehend the functioning instructions of the tractor and know about the
safety standards related to 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 mention 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 to
be used to 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 in the working environment.

Assembly
First of all, put the parts in a clean place to identify them easier. Check the parts using
the list that comes inside the packing box.
Using the set of wrenches
NOTE We recommend wearing gloves, especially while assembling the disc gangs.
Use two box end wrenches (A) to tighten the nuts of the disc gang, being one to hold
the axle nut on one side while the other tighten the nut to the other end, thereby preventing
the axle from rotating.
Use a box end wrench (B) to tighten the nuts on the bearing bolts.
Use a box end wrench (C) to tighten the nuts on the traction set.
