• Check for loose, broken, missing or damaged parts. Ensure that everything has been properly repaired.
• Check that the seat belt is in good condition. If it is not, replace it.
• Check that implements are correctly installed.
• Check that the PTO output speed is in keeping with the implement PTO input speed.
• Ensure that all PTO shaft locking devices are engaged.
• Ensure that the tractor PTO guard and the shaft guards are in place and operating correctly.
• Check to ensure that the tractor is correctly balanced.
WARNING:
An unbalanced tractor could overturn and cause serious injury or death.
Ensure that front frame counterweights, wheel weights and wheel ballasts are used as
recommended by the manufacturer. Do not add extra counterweights to compensate
for an overloaded tractor; the load must be reduced instead.
• Check the condition and pressure of tires (absence of cuts and bulges). Replace worn or damaged tires.
• Check the correct operation of the brake pedals and the parking brake. Adjust if necessary.
• Check the hydraulic system for the tractor and the implement as well as the tractor fuel system: Correct
tightening of all the unions; no damage to the lines, pipes and hoses; hydraulic systems do not cross
one another.
WARNING: Leaks of pressurized fluid
may not be visible.
Fuel or hydraulic fluid under pressure
can penetrate the skin or eyes and
cause serious physical injury,
blindness or death.
Use a piece of cardboard or wood to
detect leaks. DO NOT USE YOUR
BARE HANDS. Wear safety goggles
for eye protection. If any fluid
penetrates the skin, seek medical
advice within a few hours from a
doctor familiar with this type of
injury.
WARNING:
Release the pressure of the hydraulic
or fuel systems before disconnecting
them.

• Have any leakages or damaged parts repaired or replaced. Do this before each working day
• Check the engine cooling system and add coolant if required.
WARNING:
The liquid cooling system builds up pressure as the temperature increases.
Stop the engine and let the system cool before removing the radiator filler plug.
• All maintenance procedures must have been complied with.
• Check that the weight of the tractor/implement assembly is less than the tractor total permissible load.
