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 in addition to being prohibited by the

current existing 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 wheels appropriately.

• 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, 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 on 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 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.
