Repair and maintenance

During repair and maintenance work, all the applicable safety precautions and
maintenance instructions have to be followed. The engine has to be stopped and
the implements lowered before any maintenance work.
Support
If the maintenance work requires supporting the tractor, the supports have to be
suitable and the tractor has to be supported from the correct support points.
When splitting the tractor, the support points and the center of gravity for each
frame part have to be considered.
Heavy components
Tools and lifting devices have to be used in the correct way. Lifting slings should
be in a vertical position and lifting and lowering should be vertical as often as
possible.
Substances
Suitable protection must be worn when handling toxic or harmful chemicals such
as fuel, oil, grease or fluids. During and after such maintenance work, all affected
parts and equipment must be carefully covered or cleaned. Excess substances
must be disposed of in the correct way.
Pressure
Pressurized circuits should not be opened immediately after the engine has
stopped. Opening pressurized circuits can be dangerous if the pressure is not
carefully released first.
Electrical system
The main power has to be turned off before disconnecting or reconnecting the
battery. The battery leads have to be connected and disconnected in the correct
order and with the correct polarity.
IMPORTANT: After maintenance work, all replacements for parts with a safety
sign on them must include also the new safety sign.
