1.2.1.2 Implements
Makeshift, unsuitable and faulty tools can cause problems and accidents. Never use the wrong tools, as
these may put you at risk and compromise the work done.
Only use the special tools recommended by the manufacturer to disassemble, service and refit the
components of the tractor.
Using the correct specific tools will make work less tiring and quicker, letting you save costs while being
sure that the job has been done correctly.
Never use:
- A hammer with a loose head or a damaged handle.
- Pliers or pieces of metal instead of a hammer;
- Drill bits or screws instead of pin punches;
- Worn wrenches or wrenches repaired with welds;
- A steel hammer to tap bearings or heat-treated components (use a bronze or brass hammer).
Certain procedures on components of the tractor require the engine to be separated from the gearbox
and the separation of the front and rear transmission casings. These operations are facilitated and made
safer by using the specific separator trolley kit.
When lifting heavy parts, make sure that all chains, brackets, hooks, cables and ropes used for lifting are
compliant with EC standards. Unless specified otherwise, an adjustable hoisting bracket must be used when
lifting all heavy parts.
All chains and cables used must be parallel to each other and maintained as close as possible to vertical
with respect to the object lifted.
1.2.1.3 First Aid
Mechanics are exposed to a number of risks in
the workplace.
Treat injuries with disinfectant products and
sterile materials, which must be kept in a
specific first aid box equipped in accordance
with applicable legislation.
